Best RV Slide Out Supports for Campers and Travel Trailers

#1 · Best Overall

1. Kohree 4PCS Slide Out Supports

• Dimensions: 21.45 x 9.25 x 5.31 in
• Weight: 18.7 lb
• Load Capacity: 20000 lb
• Material Type: Steel

Best for: Large-RV four-jack support.

Why it ranks #1: Four jacks and a stated 20,000-pound total capacity suit the listing’s intended large fifth wheels and Class A RVs.

Four steel supports and a listed 20,000-pound total capacity distinguish this Kohree set for owners of larger fifth wheels or Class A RVs seeking support beneath a heavy slide-out. The four-piece configuration also spreads support points beyond the two-jack format.

Kohree positions this set for large fifth wheels and Class A RVs, and says the four supports can reduce shake by up to 70% for heavy slide-outs. That makes the total-capacity claim and four-point arrangement relevant to buyers prioritizing movement control on an extended room. Steel construction is specified, and the supports are listed for campers, RVs, and trailers. At 18.7 pounds, the complete set has a defined carry weight for storage planning.

Skip it if you need a stated adjustable height; Camco Eaz-Lift supports adjust from 19 to 49 inches.

This set suits large-RV owners who prioritize four support points and the listed total capacity for a heavy slide-out. Its supplied details do not state a height range, so buyers needing a specified adjustment span should consider that limitation.

#2 · Reversible Top Design

2. Camco Eaz-Lift Supports

• Weight: 1 lb

Best for: Reversible-top rail support.

Why it ranks #2: Its reversible tops work on slide-out rails or flat-bottom rooms, and the supports adjust from 19 to 49 inches with locked positions.

Reversible tops let the Camco Eaz-Lift pair support either slide-out rails or flat-bottom slide-outs, giving owners a choice of contact style. Its 19-to-49-inch adjustment range and incremental lock positions add flexibility for matching the support to the setup.

Camco says these supports help keep an extended slide-out level and prevent rails from sagging or bending, addressing strain during prolonged use. The reversible tops accommodate rails up to 51⁄2 inches wide or flat-bottom slide-outs, so the contact arrangement can suit either listed form. Height adjusts from 19 to 49 inches with incremental lock positions, while the threaded rod's turn handle allows fine adjustment. Each steel support can withstand up to 5,000 pounds, according to the supplied facts.

Skip it if you need a listed 6,000-pound capacity; RVshark RS1231 specifies 6,000 pounds per support.

This Camco pair suits owners supporting a rail or flat-bottom slide-out for an extended stay, especially when adjustable height and fine positioning matter. Its stated 5,000-pound capacity per support is an important application boundary.

#3 · Higher Per-Jack Capacity

3. RVshark RS1231 Supports

• Load Capacity: 6000 lb
• Material Type: Alloy Steel

Best for: Dual-mode 6,000-pound pair.

Why it ranks #3: The pair is rated at 6,000 pounds per jack, above the 5,000-pound capacity listed for several competing two-jack options.

A 6,000-pound capacity per support is the central specification of this RVshark pair, offering a stated 1,000-pound margin over the 5,000-pound limit it references. Drill and manual lifting modes give owners a choice when adjusting the supports at camp.

The alloy-steel jacks use reinforced galvanized tubes, a combination RVshark connects with its 6,000-pound capacity and support against sagging or sway. The two lifting modes let users operate with a 20-to-24-volt cordless drill or manually, adapting setup to available equipment. Two supports are included, so the format suits buyers seeking a pair rather than a four-point kit. The supplied specifications do not give a height range, so support clearance cannot be assessed from a listed span.

Skip it if you need a stated height range; Camco Eaz-Lift adjusts from 19 to 49 inches.

Choose the RVshark pair if its listed 6,000-pound capacity and drill-or-manual operation match your support needs. Since the supplied information gives no adjustment range, buyers should not rely on it for a particular clearance.

#4 · Flat Top Contact

4. Kohree Flat Top Supports

• Dimensions: 21.45 x 9.25 x 5.31 in
• Weight: 18.3 lb
• Load Capacity: 5000 lb
• Material Type: Stainless Steel

Best for: Flat-top drill-adjusted pair.

Why it ranks #4: The flat top block is designed to provide contact without an extra wood block, and the set includes a drill socket and hand crank.

A flat top support block lets this two-jack Kohree set contact a slide-out without a separate wood block, while its included drill socket enables powered height adjustment. The combination favors RV owners looking for a compact pair with a more direct setup workflow.

The flat top design is specified to provide a sturdy support surface without an extra block, reducing one item to bring to the setup. Kohree includes a drill socket and hand-crank handle, so users can choose powered raising and lowering or manual operation. The two supports are listed for campers, motorhomes, RVs, and trailers. Stainless-steel material is specified, while the stated load capacity is 5,000 pounds; check that capacity against the intended support application.

Skip it if you need four supports for a heavy slide-out; Kohree's 4PCS set lists 20,000 pounds total capacity.

Pick this pair if a flat contact surface and a choice of drill or hand-crank adjustment matter for your RV setup. The listed 5,000-pound capacity and two-jack quantity are important limits to weigh for the intended use.

#5

5. Garvee Slide Out Jacks

• Dimensions: 24.61 x 10.04 x 12.6 in
• Weight: 41.2 lb
• Load Capacity: 10000 lb
• Material Type: Alloy Steel

Best for: Wide-height four-jack setups.

Why it ranks #5: Four supports offer quick-lift adjustment from 21 to 49 inches, but the title and specifications give conflicting capacity figures.

The four-jack set combines a 21-to-49-inch quick-lift range with flat top support blocks, letting RV owners adjust support across a broad range of slide-out heights without adding separate blocks. Drill and hand-crank compatibility also gives campers a choice of setup method at the campsite.

Garvee lists a 20,000-pound support claim and alloy-steel construction, pairing substantial stated capacity with material suited to a support-jack role. The telescoping 21-to-49-inch adjustment covers varied clearances, while the flat top blocks provide a contact surface without an added wood block. Each jack is drill- and hand-crank compatible, so setup can use powered adjustment or manual operation. The four-piece quantity suits buyers who want support points beyond a two-jack set.

Skip it if you need a lighter two-jack kit; Kohree's flat-top two-support set weighs 18.3 pounds.

Choose this Garvee kit if you want four supports, broad height adjustment, and drill-or-crank operation for an RV slide-out. Its 41.2-pound listed weight is a relevant handling consideration when moving the set between storage and setup.

#6

6. RVshark RS1232 Supports

• Load Capacity: 6000lbs lb
• Material Type: Alloy Steel

Best for: Black dual-mode support pair.

Why it ranks #6: These two supports are listed at 6,000 pounds and use alloy steel; the listing describes both drill and manual lifting modes.

This black RVshark pair combines a listed 6,000-pound capacity with power and manual lifting modes, giving slide-out owners a choice of adjustment method alongside the higher stated capacity. Alloy steel and reinforced galvanized tubes are specified for the two supports.

RVshark states that each jack provides an extra 1,000 pounds of support margin over a 5,000-pound market limit, and identifies alloy steel with reinforced galvanized tubes as its construction. That combination is presented to help prevent an extending room from sagging or swaying. A 20-to-24-volt cordless drill can operate the jacks, with manual lifting also available for a different setup workflow. The two-piece quantity makes this a pair; no height range is stated in the supplied specifications.

Skip it if you need a listed adjustment span; BOYISEN BORVJ01 offers a stated 19-to-47-inch range.

This pair suits buyers who value the stated 6,000-pound capacity and a choice between drill-powered and manual operation. The supplied details omit an adjustment range, a meaningful boundary if your installation depends on a specific height.

#7

7. VEVOR Slide Out Supports

• Dimensions: 20.08 x 5.31 x 5.31 in
• Weight: 16.3 lb
• Load Capacity: 5000 lb
• Material Type: Alloy Steel

Best for: Thick-steel two-jack support.

Why it ranks #7: The two-pack is rated at 5,000 pounds per stabilizer and adjusts from 20 to 48 inches for RVs, campers, and travel trailers.

Steel pipes with a specified 2-millimeter thickness form the VEVOR pair, with each jack rated to support up to 5,000 pounds. The 20-to-48-inch adjustment range gives RV, camper, and travel-trailer owners a defined span for supporting an extended slide-out.

VEVOR lists a 5,000-pound maximum capacity for each stabilizer and says the supports help prevent sliding or sagging while the RV is occupied. The 2-millimeter-thick steel pipes provide a concrete construction specification, while adjustment from 20 to 48 inches offers a broad stated height span. Two jacks are included for RV use, and the product information also identifies campers and travel trailers as intended vehicle types. These figures help buyers compare support capacity and clearance needs.

Skip it if you want four support points; Kohree's 4PCS set provides four jacks and lists 20,000 pounds total capacity.

This VEVOR pair suits RV, camper, or travel-trailer owners whose support height falls within 20 to 48 inches and who need two jacks. Its listed 5,000-pound capacity per stabilizer is the relevant load boundary.

#8 · Longest Height Range

8. BOYISEN BORVJE01 Jacks

• Dimensions: 21.5 x 9.3 x 5.3 in
• Weight: 18.8 lb
• Load Capacity: 5000 lb
• Material Type: Alloy Steel

Best for: Tall-adjustment drill-ready pair.

Why it ranks #8: Its 20-to-49-inch adjustment range suits buyers needing substantial reach, and it can be operated with a drill or included hand crank.

A 20-to-49-inch adjustment range gives the BOYISEN pair broad vertical reach, with both an electric drill and supplied hand crank available for raising or lowering. That combination can suit RV owners who want flexible height adjustment and alternatives for the setup task.

The jacks adjust from 20 to 49 inches through thread and hole-position adjustment, giving users two ways to set the support height within the stated span. A power drill or included hand crank can raise and lower them, so setup need not depend on a single method. Each support is listed at 5,000 pounds, and alloy steel is specified. The manufacturer notes holding the U-shaped top while adjusting the thread for better adjustment, a practical detail during installation.

Skip it if you need a stated 6,000-pound rating; RVshark RS1232 lists 6,000 pounds per support.

Consider this pair if its 20-to-49-inch span fits your measured clearance and you want drill or hand-crank operation. The stated 5,000-pound capacity per support is the key boundary when matching it to the application.

#9

9. BOYISEN BORVJ01 Jacks

• Dimensions: 6 x 3 x 17 in
• Weight: 12 lb
• Load Capacity: 5000 lb
• Material Type: Alloy Steel

Best for: Stabilization-only adjustable pair.

Why it ranks #9: This two-pack has a 5,000-pound listed capacity and adjusts from 19 to 47 inches; its listing explicitly says it is for stabilization, not lifting or leveling.

A clearly stated stabilization-only role sets this BOYISEN pair apart: its 19-to-47-inch jacks help reduce bounce beneath an extended slide room, but are not for lifting or leveling the RV. That distinction helps buyers plan its use appropriately.

BOYISEN describes the pair as reducing movement, wobbling, and bounce during extended stays, with a 5,000-pound capacity and alloy-steel construction specified. Its 19-to-47-inch adjustment range covers a range of support heights for campers, RVs, and trailers. The product is explicitly for stabilization only, not lifting or leveling the vehicle, so it belongs after the RV is positioned and leveled rather than serving as a leveling tool. Two jacks are included.

Skip it if you need broader adjustment; Camco Eaz-Lift extends to 49 inches and supports rails or flat bottoms.

Choose this BOYISEN pair for reducing slide-room movement during a stay when your measured height falls within 19 to 47 inches. It is for stabilization only, not vehicle lifting or leveling.

#10

10. LUSHIH RVJ26 Stabilizers

• Dimensions: 16.53 x 7.67 x 6.5 in
• Weight: 8.8 lb
• Load Capacity: 5000 lb
• Material Type: Alloy Steel

Best for: Compact-range trailer stabilizers.

Why it ranks #10: The pair is rated at 5,000 pounds each, but its 15-to-26-inch travel range is shorter than the taller alternatives in this roundup.

A 15-to-26-inch travel range gives this LUSHIH pair a defined fit window for trailer slide-out support, while each jack is rated at 5,000 pounds. Its zinc powder-coated steel construction also addresses rust and corrosion resistance for repeated outdoor use.

Each jack has a maximum lift capacity of 5,000 pounds and an 11-inch working range, giving buyers concrete limits for matching support height and load. The triangular threaded screw and M18 nut are specified as the support mechanism, while the U-shaped tops measure 5.94 by 2.95 by 0.9 inches. Zinc powder coating on heavy-duty steel is intended to resist rust and corrosion. Installation instructions call for a level surface and chocked wheels before placing the jacks.

Skip it if you need support above 26 inches; BOYISEN BORVJE01 adjusts from 20 to 49 inches.

This pair fits trailer owners whose measured support height falls within its 15-to-26-inch travel range and who want coated steel. It is not the choice for a slide-out needing support above that listed range.
