A strong F-150 suspension choice matches your truck’s year and drivetrain, then supplies the lift, load support, or replacement parts your use calls for. For a complete lift setup, the Rough Country 3-inch M1 kit pairs loaded front struts with rear shocks, blocks, and forged upper control arms. Other picks address narrower jobs: leveling the front, supporting a loaded rear, or refreshing worn front-end components.
Fitment matters as much as the kit’s headline features: several options cover only specific model years or 2WD/4WD configurations, and some control-arm kits require wheel changes or spacers. Compare the intended job and listed compatibility before buying; these products are not interchangeable, and a lift kit is not a substitute for a full worn-parts rebuild.
The Rough Country 3-inch M1 Lift Kit is the strongest all-around choice for a compatible 2014–2020 F-150 4WD when you want a complete lift setup. It includes M1 loaded struts, rear shocks, lift blocks, and forged aluminum upper control arms, and lists maintaining factory ride quality as a feature. Choose it for a front lift and rear components in one kit, but verify your truck’s exact fitment and consider certified installation as Rough Country recommends.

Detailed Reviews: Best Suspension For F150

#1 · Best Overall
1. Rough Country M1 Lift Kit
- Weight: 88.4 lb
- Material: Alloy Steel, Aluminum, Rubber, Zinc
- Material Type: Alloy Steel, Aluminum, Rubber, Zinc
Best for: M1-equipped three-inch lift.
Why it ranks #1: For 2014–2020 F-150 4WD, it combines a 3-inch lift, M1 loaded struts, rear shocks, lift blocks, and forged upper control arms.
Premium M1 loaded coil-spring struts distinguish this Rough Country 3-inch lift, which also includes M1 rear shocks for compatible 2014–2020 F-150 4WD trucks. The package combines ground-clearance gains with forged upper control arms, giving buyers a coordinated front-and-rear system rather than a leveling-only strut pair.
The loaded M1 struts and monotube rear shocks cover both ends of the truck, while the included lift blocks and forged aluminum upper control arms complete the listed lift components. Rough Country says the kit maintains factory ride quality and optimum alignment angles, with Clevite rubber bushings included. Its installation is described as suitable for at-home work with company support, though the safety information recommends a certified technician and requires suspension knowledge and post-install checks.
- 3-inch lift kit for specified 2014–2020 F-150 4WD
- M1 loaded struts and monotube rear shocks
- Forged aluminum upper control arms and lift blocks included
- Clevite rubber bushings and alignment-angle support stated
- Rough Country recommends certified-technician installation and post-install checks.
Skip it if you need fitment through 2025 with a front leveling-only setup; Rough Country 501075 lists 2014–2025 F-150 4WD.
This package fits owners of 2014–2020 F-150 4WD trucks seeking a full three-inch lift with M1 dampers and control arms. Account for the recommendation for certified installation and post-install checks.

#2 · Best N3 Lift
2. Rough Country N3 Lift Kit
- Weight: 88.4 lb
- Material: Alloy Steel, Aluminum, Rubber, Zinc
- Material Type: Alloy Steel, Aluminum, Rubber, Zinc
Best for: Three-inch trail lift.
Why it ranks #2: This 2014–2020 4WD kit supplies 3-inch front lift, rear blocks, N3 struts and shocks, and forged aluminum upper control arms.
A 3-inch front lift paired with rear blocks gives this Rough Country kit its defining stance, while supporting tires up to 34 inches. Pre-loaded N3 struts and matching rear shocks make it a complete suspension upgrade for F-150 4WD owners seeking added ground clearance and components for both on-road and off-road use.
The pre-loaded N3 struts and rear shocks arrive as matched components, giving buyers a coordinated front-and-rear suspension package rather than separate dampers to assemble. Ten-stage variable valving and nitrogen charging support controlled operation across changing conditions, while the forged aluminum upper control arms and included lift blocks complete the lift system. Rough Country describes the kit as bolt-on, which gives experienced installers a more direct upgrade path; its stated fitment is F-150 4WD from 2014 through 2020.
- 3-inch front lift with rear blocks
- Supports tires up to 34 inches
- Pre-loaded N3 struts and matching rear shocks
- Forged aluminum upper control arms included
- The stated 2014–2020 fitment excludes newer F-150 model years.
Skip it if you own a 2021-or-newer F-150; the Rough Country 501075 struts cover model years through 2025.
Choose this kit if you have a 2014–2020 F-150 4WD and want a coordinated lift, shocks, and forged arms for larger tires and added clearance. Its defined model-year and drivetrain fitment sets the boundary.

#3 · Best Shock Refresh
3. Detroit Axle 4WD Strut Kit
- Weight: 64.9 lb
- Material: Rubber, Spring Steel
- Material Type: Rubber, Spring Steel
Best for: Complete older-truck damper set.
Why it ranks #3: For 2009–2013 F-150 4WD, it includes two front struts with coil springs and two rear shock absorbers, ready for installation.
Front struts with coil springs arrive assembled alongside rear shocks in this Detroit Axle kit, giving specified 2009–2013 F-150 4WD owners all four listed dampers. The ready-to-install assemblies require no additional work or special tool for installation, a practical advantage for a replacement job centered on worn struts and shocks.
The two front strut assemblies include coil springs, while two rear shock absorbers complete the four-corner damper set. Detroit Axle says the assemblies are ready for installation without additional work or special tools, simplifying the listed replacement workflow compared with a product requiring separate spring assembly. Its fitment details specify 2009–2013 F-150 4WD versions, with engine and trim notes provided for certain years, so this is a replacement set rather than a lift kit or front-end rebuild.
- Two front struts with coil springs
- Two rear shock absorbers included
- Assemblies listed as ready for installation
- No additional work or special tools required for installation
- It is a replacement damper set, not a lift or control-arm kit.
Skip it if you need a front-end rebuild for a 2009–2013 RWD F-150; Detroit Axle's 14CQS2500802 kit lists control arms and steering parts.
Choose this set for a specified 2009–2013 F-150 4WD replacement involving both front struts and rear shocks. It does not provide a lift, control arms, or the broader steering components found in rebuild kits.

#4 · Best Rear Support
4. RETRUE Rear Air Bags
- Material: Reinforced Rubber, Alloy Steel
- Material Type: Reinforced Rubber, Alloy Steel
Best for: Rear air-bag load support.
Why it ranks #4: Its air-bag kit fits many 2015–2025 F-150 2WD and 4WD models, with brackets, tubing, fittings, and hardware included.
A rear air-bag kit gives this RETRUE package a distinct role: supporting the rear suspension on listed 2015–2025 F-150 2WD and 4WD trucks. It includes bags, brackets, tubing, fittings, and hardware, providing the parts for an air-suspension installation rather than a conventional strut or shock replacement.
The reinforced-rubber air bags work with the included alloy-steel brackets, tubing, and air fittings to form a rear support system. This package is aimed at owners seeking air-bag suspension components, not a front lift or full set of dampers. Fitment has important exclusions: it does not fit Raptor models, trucks with CCD, an in-bed hitch, leveling arms outside the rear frame, or self-leveling headlights. The listed installation also requires eight inches of frame-to-tire clearance.
- Stated fitment for 2015–2025 F-150 2WD and 4WD
- Reinforced-rubber air bags with alloy-steel brackets
- Tubing, air fittings, and hardware included
- Eight-inch frame-to-tire clearance requirement is specified
- It excludes Raptor, CCD, in-bed-hitch, and several other configurations.
Skip it if you own a Raptor or need front suspension parts; Rough Country 54531 is a front-and-rear lift kit for specified 4WD F-150s.
Choose this kit for a compatible 2015–2025 F-150 needing rear air-bag support. Verify that the truck clears the listed eight inches and avoids the stated exclusions before planning installation.

View on AmazonWhy it ranks #5: This rear suspension option is listed for F-150 4WD models from 2009–2025 and includes a five-year manufacturer warranty.
RoadActive Suspension lists strength and stability as the central benefit of its 3611-YHD system, for F-150 4WD models spanning 2009–2025. Its included component is identified as a leaf spring, making this a focused suspension option rather than a package of struts, shocks, and control arms.
The broad stated fitment range covers F-150 4WD trucks from 2009 through 2025, while the included component is a leaf spring. That focused format may suit an owner seeking the listed strength and stability benefit without buying a multi-part front-end kit. RoadActive Suspension says most of its kits install in as little as 45 minutes and require no readjustments; those claims are stated for most kits, so they should not be treated as a guaranteed installation time for every vehicle.
- Stated fitment covers F-150 4WD from 2009–2025
- Leaf spring is the listed included component
- RoadActive Suspension cites added strength and stability
- Most kits reportedly install in as little as 45 minutes without readjustment
- The supplied listing identifies a leaf spring, not a complete strut-and-shock package.
Skip it if you need a complete 2009–2013 F-150 4WD damper set; Detroit Axle's 4AQ1201111 includes front struts and rear shocks.
Consider this focused option if your 2009–2025 F-150 4WD needs the strength and stability benefit described for the RAS system. The listed component is a leaf spring, so it is not a full suspension refresh.

#6 · Best Front Leveling
6. Rough Country N3 Leveling Struts
- Weight: 47.4 lb
- Material: Alloy Steel, Rubber, Zinc
- Material Type: Alloy Steel, Rubber, Zinc
Best for: Front-end leveling struts.
Why it ranks #6: For 2014–2025 F-150 4WD, the pair of pre-loaded N3 struts provides a 2-inch front lift without a full-kit component list.
Pre-loaded N3 struts provide this Rough Country kit’s key convenience: a pair of front strut assemblies for leveling compatible F-150 4WD trucks. The 2-inch lift addresses factory rake and adds front ground clearance, while the bolt-on format keeps the upgrade focused on the front rather than a complete suspension system.
The two loaded struts combine the coil and strut assembly, avoiding a separate coil-spring transfer as part of the listed product format. Rough Country pairs a 1-3/8-inch bore with nitrogen charging and precision valving, features it associates with control and handling on highway and trail. The 2-inch front lift is intended to level the truck and increase clearance; buyers wanting rear shocks or control arms will need a broader package, since only two loaded struts are included.
- Two pre-loaded N3 leveling struts included
- 2-inch lift addresses factory rake
- 1-3/8-inch bore with nitrogen charging
- Bolt-on format and stated 2014–2025 F-150 4WD fitment
- This set includes only two front struts, not rear shocks or control arms.
Skip it if you need a complete 3-inch lift with rear shocks and arms; Rough Country 54531 bundles those components for 2014–2020 4WD trucks.
This is a fit for F-150 4WD owners from 2014–2025 seeking a front-only 2-inch leveling change. Choose a larger kit instead if your job also calls for rear dampers or control arms.

7. Detroit Axle RWD 14-Piece Kit
- Weight: 115.7 lb
- Material: Metal
- Material Type: Metal
Best for: RWD front-end rebuild package.
Why it ranks #7: This 2009–2013 RWD front-end kit includes control arms, sway bars, tie rods, boots, and front struts, but excludes 4WD trucks.
Four front control arms with ball joints headline this Detroit Axle 14-piece kit for specified 2009–2013 F-150 RWD models. It also groups front sway bars, tie rods, boots, and struts, making it a broad front-end refresh option for buyers replacing multiple listed suspension and steering components at once.
The four upper and lower control arms arrive with ball joints, alongside two sway bars, four tie rods, two boots, and two front struts. Grouping these parts can simplify sourcing for a multi-component front-end rebuild, rather than purchasing each listed category separately. Fitment specifies RWD F-150 models from 2009–2013, with engine notes and an exclusion for Raptor models. This is a front-end kit, not a rear suspension package or a lift system.
- Four upper and lower control arms with ball joints
- Two front sway bars and four tie rods included
- Two front struts and two boots included
- Broad set of listed front-end replacement components
- The stated F-150 fitment is RWD and excludes Raptor models.
Skip it if you have a 2009–2013 F-150 4WD needing front struts and rear shocks; Detroit Axle's 4AQ1201111 lists that setup.
This kit suits owners rebuilding the front end of a specified 2009–2013 F-150 RWD, with multiple steering and suspension parts grouped together. Its stated coverage excludes 4WD and Raptor configurations.

View on AmazonWhy it ranks #8: It bundles front control arms, shocks, and tie-rod components for listed 1997–2003 F-150 4WD fitments, making it a targeted rebuild.
Four front control arms with ball joints anchor this Detroit Axle kit, giving owners of specified older F-150 4WD models a broad front-end replacement package. It also includes front shocks and inner and outer tie rods, so the listed components address several front suspension and steering connections together.
The kit combines upper and lower control arms with ball joints, two front shock absorbers, and four inner and outer tie rods. For a buyer refreshing multiple front-end components at once, that grouping reduces the need to source those listed parts individually. Its stated F-150 coverage names 1997–2003 4WD models; the title also mentions F-250 and Expedition, but the supplied fitment details here identify the F-150 years and drivetrain specifically.
- Four upper and lower control arms with ball joints
- Two front shock absorbers included
- Four inner and outer tie rods included
- Grouped components support a multi-part front-end refresh
- Its stated F-150 coverage centers on 1997–2003 4WD models, limiting use on newer trucks.
Skip it if you have a 2009–2013 F-150 4WD needing front and rear dampers; Detroit Axle's 4AQ1201111 kit includes both.
This package suits owners refreshing several front-end components on a listed 1997–2003 F-150 4WD. Its coverage is not a general match for later trucks, and the supplied kit contents focus on the front end.

9. KSP Forged Aluminum Control Arms
- Material: Aluminum
- Material Type: Aluminum
Best for: Forged-aluminum lifted-truck arms.
Why it ranks #9: These upper arms fit listed 2004–2020 F-150 applications with 2–4-inch leveling lifts, but they do not provide a complete suspension.
One-piece forged T6 aluminum construction defines these KSP upper control arms, offering F-150 owners a lighter, rust-resistant alternative for 2–4-inch leveling lifts. The listing covers F-150 models from 2004–2020 and also names Expedition and Navigator applications, while CNC machining is specified to maintain the arms’ dimensions.
The forged, one-piece aluminum design avoids welded joints, and KSP says T6 aluminum resists rust, a useful distinction for owners dealing with melting snow. CNC machining supports dimensional accuracy, while magnetic-particle inspection is performed during production. The serviceable greasable socket lets owners add fresh grease to reduce corrosion and wear, linking a maintenance task to component longevity. These are upper control arms only, so they do not supply struts, shocks, or the rest of a leveling kit.
- One-piece forged T6 aluminum construction
- Listed for 2–4-inch leveling lifts
- CNC machining and production magnetic-particle inspection
- Greasable socket supports maintenance to reduce corrosion and wear
- Only upper control arms are included; struts, shocks, and lift hardware are not.
Skip it if you want steel arms rather than forged aluminum; KSP's 3C293058 is a steel tubular option for listed F-150 lifts.
These arms suit owners of listed 2004–2020 F-150s seeking forged aluminum upper control arms for a 2–4-inch leveling lift. They are a component upgrade, not a complete suspension kit.

10. KSP Steel Control Arms
- Weight: 6.6 kg
- Material: Steel
- Material Type: Steel
Best for: Lifted-truck control-arm replacement.
Why it ranks #10: The replacement upper arms are listed for 2004–2020 F-150 and 2–4-inch lifts, but stock ET44 wheels may rub without added clearance.
KSP’s tubular steel upper control arms are listed for 2–4-inch lifted F-150s, serving owners replacing factory-style arms while changing suspension height. The listing covers 2004–2020 F-150 models and calls out a wheel-clearance constraint: conservative stock wheels with ET44 can rub, making wheel setup an important part of the decision.
These replacement upper arms are intended for a 2–4-inch lift, so they address the control-arm portion of a suspension change rather than supplying a full lift kit. KSP specifies steel construction and says the ball joints require no extra grease; its note to tighten the zerk after refilling gives owners a maintenance detail to follow. Stock ET44 wheels can cause tire rub against the arm, while the listing calls for at least a 1.5-inch spacer or a zero-offset aftermarket wheel in that situation.
- Listed for 2004–2020 F-150 models
- Intended for 2–4-inch lifts
- Steel tubular replacement upper control arms
- Ball joints do not require extra grease
- Stock ET44 wheels can rub; the listing calls for a spacer or zero-offset wheel.
Skip it if you want forged aluminum arms and corrosion resistance; KSP's 3C298058 uses one-piece T6 aluminum construction.
These arms suit owners of listed 2004–2020 F-150s replacing upper control arms on a 2–4-inch lift. Check the wheel-clearance constraint in your setup: stock ET44 wheels can rub the arm.

View on AmazonFitment traps to check before ordering
The most consequential fitment trap is assuming that “F-150” alone confirms compatibility. The lift kits and leveling struts here specify 4WD and defined model-year ranges, while the Detroit Axle 14-piece kit is for 2009–2013 RWD and excludes Raptor models. RETRUE lists exclusions including Raptor, CCD, in-bed hitch, and certain other configurations; it also requires eight inches of frame-to-tire clearance.
KSP’s steel-arm listing warns that conservative ET44 stock wheels can rub the arm and calls for at least a 1.5-inch spacer or a zero-offset aftermarket wheel. Check the exact year, drivetrain, trim, suspension equipment, and wheel setup against the manufacturer’s fitment details before purchasing.
The listed date ranges are not a guarantee that every configuration within them fits.
Lift height can create a parts-matching problem
A lift or leveling change can make a control arm’s stated lift range relevant, but the supplied listings do not establish that every combination preserves ideal alignment or avoids rubbing. The Rough Country kits pair their lift components with forged upper control arms, while the separate KSP arms are described for 2–4-inch lifts. Buying an arm separately therefore calls for checking its fit with the exact lift and wheel setup, rather than treating the stated height range as universal compatibility.
There is also a scope trade-off: a complete lift kit includes several matched suspension components, whereas a pair of leveling struts or standalone arms changes only part of the system. Rough Country recommends certified installation for lift systems, and its listing notes that installation knowledge and post-install checks matter.
Plan for fitment verification and installation checks rather than assuming bolt-on means no follow-up.
How to Choose F-150 Suspension Parts
Match the suspension job
Start by deciding whether you need a lift, a level front stance, rear load support, or replacement parts. The Rough Country M1 and N3 kits combine a 3-inch front lift with rear blocks and shocks; the Rough Country N3 leveling struts list a 2-inch front lift. RETRUE supplies rear air bags, while RAS is a separate rear suspension option.
Detroit Axle’s kits focus on replacing front-end components or shocks rather than providing a lift. Buyers seeking a coordinated lift package should consider either Rough Country kit; those addressing a rear-support need should compare the air bags and RAS; and owners refreshing worn parts should look to the Detroit Axle kits that match their drivetrain and years.
Verify year and drivetrain
Choose a product only after matching its listed model years and drivetrain to your truck. Coverage ranges from Detroit Axle’s older 1997–2003 4WD front-end kit to the RAS listing for 2009–2025 F-150 4WD. The Rough Country lift kits specify 2014–2020 4WD, while its leveling struts list 2014–2025 4WD.
Detroit Axle’s strut kit covers 2009–2013 4WD; its 14-piece front kit covers 2009–2013 RWD and excludes Raptor. Buyers with older trucks should focus on the matching Detroit Axle fitment, while owners of newer 4WD trucks can compare the Rough Country and rear-support options.
Confirm trim and configuration details before ordering.
Compare what the kit includes
Look at the included components to see whether a listing covers your repair or upgrade without leaving out a needed part. The M1 and N3 lift kits include front struts, rear shocks, lift blocks, and forged upper control arms. Detroit Axle’s 2009–2013 4WD kit includes front struts with coil springs and rear shocks, while its RWD 14-piece kit adds control arms, sway bars, tie rods, boots, and front struts.
RETRUE’s kit includes air bags, brackets, tubing, fittings, and hardware; the separate KSP listings are control arms only. Buyers planning a broad refresh may prefer a multi-component kit; those replacing one worn or missing component should avoid assuming a smaller listing includes the rest.
Which F-150 suspension setup fits your needs?
For a complete 3-inch lift on a compatible 2014–2020 4WD truck, choose the Rough Country M1 Lift Kit; it leads with front struts, rear shocks, blocks, and forged upper control arms. The Rough Country N3 Lift Kit offers a similar package with N3 components. If your priority is leveling the front rather than installing a full lift, consider Rough Country N3 Leveling Struts for listed 2014–2025 4WD models.
For rear air support, compare RETRUE Rear Air Bags with RAS RoadActive Suspension after checking exclusions and fitment. Owners refreshing an older 4WD should examine Detroit Axle 4WD Strut Kit or its older front-end kit; RWD owners may consider Detroit Axle RWD 14-Piece Kit.
KSP’s arms suit a narrower, lift-related replacement need.

Frequently Asked Questions
Will a suspension lift change my F-150’s alignment or require other adjustments?
Yes. A lift or leveling change can affect suspension geometry and alignment, so plan to have alignment checked after installation and follow the kit maker’s instructions for related adjustments. Exact needs depend on the kit and truck configuration; confirm requirements with the installer before choosing parts.
How do I confirm whether a suspension kit fits my F-150’s year, drivetrain, and trim?
Check the product’s stated year range and drivetrain against your truck’s details, then verify trim and any listed exclusions with the manufacturer or seller. Do not rely on model name alone: the listed kits vary by year and 4WD or RWD fitment. Confirm compatibility before ordering or scheduling installation.
Should I choose rear air bags or a suspension lift for towing and hauling?
Choose based on the job: rear air bags are a rear-support option, while a lift changes suspension height and setup. Compare the products’ stated fitment and exclusions, and confirm they suit your truck and intended use. A lift kit should not be treated as a substitute for checking load limits.
When are leveling struts a better fit than a complete lift kit?
Leveling struts are worth considering when your priority is raising the front rather than installing a complete lift setup. The listed Rough Country struts fit certain 4WD models, while the M1 kit includes front and rear components. Verify exact compatibility and installation requirements for your truck.
What should I check before choosing a replacement suspension kit?
Start with drivetrain and fitment, then identify which parts the kit actually includes. The listed options range from front-end refresh kits to rear support and complete lift setups. If you are unsure which components your truck needs, have an installer inspect it before selecting a kit.
Final Words
For a compatible 2014–2020 F-150 4WD needing a complete lift, the Rough Country M1 kit is the strongest all-around choice, with front struts, rear shocks, blocks, and forged upper control arms. Choose leveling struts for a front-focused change, or compare the rear air support options for towing and hauling needs. For any pick, confirm exact fitment and follow the manufacturer’s installation guidance.
