Best Floor Shifter For Th350: Compare 10 Compatible Shifters

#1 · Best Overall

1. B&M 80675 StarShifter

• Weight: 4.04 kg
• Handle Material: Metal
• Material: Plastic

Best for: Classic adjustable StarShifter control.

Why it ranks #1: The listing names TH350 compatibility and includes detent and ratchet modes, a 5-foot cable, backup-light and neutral-safety switches, and reverse lockout.

The B&M StarShifter combines straight-line detent operation with trigger-activated ratchet action in Low, letting drivers choose between normal automatic use and manual gear control. Its listed five-foot cable, backup-light and neutral-safety switches, and reverse lockout make it a feature-rich option for a TH350 installation.

In straight-line detent mode, the StarShifter supports ordinary automatic operation; lifting the trigger in Low changes it to ratchet action for manual selection. That two-mode mechanism gives a TH350 driver different control styles without changing shifters. The included five-foot cable helps define the installation reach, while the backup-light switch, neutral-safety switch, and NHRA/IHRA reverse lockout add specified electrical and safety functions. The listing identifies it for most popular three-speed automatics.

Skip it if you need a cable run longer than five feet; the Queencar 80775 Unimatic lists a five-foot cable but provides no longer length specification.

This B&M suits a TH350 owner who wants both normal detent operation and ratchet control, with listed switches and a five-foot cable. Check the cable route and length against the vehicle before installation.

#2 · Short Stick Option

2. Lokar FMS6350FL

• Weight: 6.4 lb
• Handle Material: Alloy Steel
• Material: Alloy Steel

Best for: Compact six-inch Lokar setup.

Why it ranks #2: This dedicated 350 floor-mount shifter has a 6-inch stick, solid adjustable linkage, positive safety lockout, and 360-degree lever rotation.

A six-inch floor-mount lever distinguishes the Lokar FMS6350FL, offering a shorter shifter profile for a 350 transmission application. Its solid adjustable linkage and positive safety lock-out add functional details beyond the compact measurement, while 360-degree lever rotation and adjustments away from the seat give the installer positioning options.

The six-inch floor-mount configuration suits buyers seeking a shorter lever than the 23-inch Lokar alternative, while the supplied listing identifies it for a 350 transmission. Solid adjustable linkage supports adjustment during setup, and the positive safety lock-out adds a stated safeguard. The lever rotates through 360 degrees for extra leg room; adjustments can be made out from under the dash and away from the seat, which can help tailor the control position to the cabin.

Skip it if you need a long lever reach; the Lokar FMS6350AL provides a listed 23-inch floor-mount shifter for a 350 transmission.

Pick this Lokar for a 350-transmission floor-mount installation where its six-inch lever, adjustable linkage, and rotating position suit the cabin. Consider the 23-inch version instead if a longer lever is central to your layout.

#3 · Gated Shift Option

3. B&M Z-Gate 80681

• Weight: 7.9 lb
• Handle Material: Alloy Steel
• Material: Alloy Steel, Plastic

Best for: Multi-make gated three-speed use.

Why it ranks #3: Its listing explicitly fits TH350 and other three-speed automatics; the internal Z-shaped gate is described as preventing overshifting and missed gears.

B&M’s patented internal Z-shaped gate is the key feature of this Z-Gate shifter, intended to prevent over-shifting and missed gears. Its universal three-speed configuration covers the TH350 alongside several other listed GM, Ford, and Chrysler automatic transmissions, making it relevant to builders working across more than one transmission family.

The Z-shaped gate gives gear selection a guided path, which addresses the stated risk of over-shifting and missing gears during operation. B&M also specifies fewer moving parts than any other automatic shifter in its line; the product description links that simpler mechanism with less possibility of failure. The chrome shifter and black base form the listed assembly, while its broad three-speed compatibility can suit a project using a TH350, TH400, 250, or 200 transmission.

Skip it if you need four-speed transmission coverage; the Lokar FMS6350FL is a floor-mount option specifically listed for a 350 transmission.

This B&M suits a TH350 owner who wants gated three-speed selection and may value compatibility across listed GM, Ford, and Chrysler applications. Check the stated transmission range against your build; four-speed use is not specified.

#4 · Long Stick Option

4. Lokar FMS6350AL

• Weight: 7.2 lb
• Handle Material: Alloy Steel
• Material: Alloy Steel

Best for: Long-reach Lokar floor mount.

Why it ranks #4: This floor-mount shifter is listed for a 350 transmission and has a 23-inch stick, solid adjustable linkage, and positive safety lockout.

The Lokar FMS6350AL pairs a 23-inch floor-mount shifter with a 350-transmission application, giving it a much longer lever than the company’s listed six-inch version. Solid adjustable linkage, a positive safety lock-out, and 360-degree lever rotation add setup and cabin-positioning choices beyond that reach.

The 23-inch lever can suit a floor-mount layout that calls for the longer reach, while the stated 350-transmission application keeps the fit focus clear. Solid adjustable linkage gives the installer an adjustment point, and the positive lock-out adds a specified safety feature. Its lever can rotate 360 degrees for extra leg room, with adjustments available out from under the dash and away from the seat, offering more flexibility when positioning the control in the cabin.

Skip it if you need a short, compact lever; the Lokar FMS6350FL provides a six-inch floor-mount shifter for a 350 transmission.

This Lokar suits a TH350-oriented floor-mount setup where a 23-inch lever and adjustable positioning match the cabin. Its long reach is the key boundary, so choose the six-inch Lokar if space calls for a shorter stick.

#5 · Direct-Mount Design

5. WnSEu TH350 Shifter

• Weight: 7.5 lb

Best for: Direct-mount TH350 installation.

Why it ranks #5: It is specified for GM Turbo 350 and includes a 12-inch chrome arm and gated lockout, but mounting directly to the transmission requires floorboard cutting.

A transmission-mounted layout is the defining feature of the WnSEu TH350 shifter, putting its mechanism directly on the GM Turbo 350 transmission. Its complete 12-inch chrome stick gives the installer a floor-shifter setup with a gated lock-out safety feature, while the mounting approach calls for floorboard modification.

The direct transmission mount keeps this shifter anchored at the TH350 rather than describing a separate floor-mount base, a layout that may suit a conversion planned around transmission access. Its 12-inch chrome arm provides the stated control length, and the gated lock-out adds a defined safety feature. Installation has a significant implication: the floorboard must be cut, and professional installation is strongly recommended. No installation instructions are listed, so plan the work accordingly.

Skip it if you need a floor-mounted base or supplied installation instructions; this model mounts directly to the transmission and calls for floorboard cutting.

Choose this WnSEu for a GM Turbo 350 project where direct transmission mounting and a 12-inch chrome stick suit the layout. It is a poor match for an installation that cannot accommodate floorboard cutting or professional fitting.

#6

6. Queencar 80775 Unimatic

• Handle Material: Plastic
• Material: Plastic

Best for: Broad-compatibility Unimatic option.

Why it ranks #6: The listing includes GM 350 compatibility and a 5-foot cable, with support for several other transmissions; check the PRNDL-switch installation-kit note where applicable.

The Queencar 80775 Unimatic pairs a five-foot cable with a broad transmission-compatibility list that includes the GM TH350. Its stated coverage extends to several other GM automatic transmissions, giving buyers a route to consider the same shifter for more than one listed transmission application.

A five-foot cable is explicitly included in the product description, giving the installer a defined cable length to work into a TH350 layout. The compatibility list also names TH400, TH250, TH200, 700R4, 200-4R, 4L60E, and 4L65E, with the 4L65E entry noting a PRNDL switch requiring a B&M installation kit. That breadth is useful when comparing applications, though the supplied information does not detail shift modes or safety switches.

Skip it if you need documented ratchet operation and safety switches; the B&M 80675 StarShifter lists both detent and ratchet modes plus switches.

Consider the Unimatic for a TH350 project where its five-foot cable and broad listed GM coverage match the plan. If ratchet operation or safety-switch specifications are essential, the supplied details do not establish them.

#7

7. Xxamz 80675 Shifter

• Weight: 10.1 lb

Best for: Broad-fit ratchet shifter applications.

Why it ranks #7: This three-speed ratchet shifter lists TH350 compatibility and also fits several other transmission families, but the supplied details name no cable or switches.

Ratchet-style gear selection sets this 80675 shifter apart, pairing positive detent control with a compact floor-mounted format for three-speed automatic applications. Its listed range includes the GM TH350 and several other transmission families, so the compatibility detail can help builders assess whether one shifter suits a multi-make project.

The ratchet mechanism and positive detent control provide defined gear selection for the stated three-speed applications, a useful distinction for drivers seeking more than an unspecified free-moving lever. The floor-mounted format places the control in the cabin, while compatibility covers GM TH350, TH400, TH250, and TH200, plus Ford C4/C6 and Chrysler A727/A904. That broad list is practical for comparing fit across project platforms, but the supplied details do not specify cable length or installation hardware.

Skip it if you require a stated cable length or included installation hardware; the B&M 80675 StarShifter lists a five-foot cable and switches.

Consider this Xxamz shifter for a three-speed TH350 project where ratchet selection and its listed cross-make compatibility are useful. Verify that the unspecified cable and hardware details work with your installation plan.

#8

8. Achilioson 80675 Shifter

• Handle Material: Metal
• Material: Metal

Best for: StarShifter-style dual-mode control.

Why it ranks #8: The listing confirms TH350 fit and identifies a dual-mode ratchet floor shifter, while explicitly excluding TH700R4, TH200-4R, and AOD transmissions.

Dual-mode ratchet operation is the distinguishing claim for this Achilioson 80675 shifter, which is described as compatible with B&M StarShifter applications. It lists the GM TH350 among supported transmissions, but its exclusions are just as important: TH700R4, TH2004R, AOD, and reverse-mode manual valve bodies are not supported.

The StarShifter compatibility and dual-mode ratchet positioning make this a possible fit for a TH350 build seeking that style of control. The stated transmission range also includes GM TH400, TH250, and TH200, alongside Ford C4/C6 and Chrysler A727/A904 applications. Its exclusions narrow the choice: it does not work with TH700R4, TH2004R, or AOD transmissions, and cannot be used with a reverse-mode manual valve body, so check those details before installation.

Skip it if you run a TH700R4, TH2004R, AOD, or reverse-mode manual valve body; the B&M 80775 Unimatic lists several of those GM transmissions.

Choose this Achilioson for a TH350 or another listed transmission when StarShifter-style dual-mode ratchet control suits the build. Its explicit exclusions make it unsuitable for several common alternatives, including AOD and TH700R4.

#9

9. YOMIRACING 80675 Shifter

• Handle Material: Aluminum
• Material: Aluminum

Best for: Flexible linear and ratchet shifting.

Why it ranks #9: Its listing includes TH350 compatibility and both linear and ratchet-style operation, but supplied details provide limited information on included installation components.

Switchable linear and ratchet shift modes define the YOMIRACING 80675, adding two operating styles to a floor shifter compatible with GM TH350 transmissions. Its stated transmission range also includes TH400, TH250, and 200 automatics, making it a candidate for builds that need mode flexibility across these applications.

The ability to function as both a linear shifter and a ratchet shifter gives the driver a choice of operating mode, according to the product description. Compatibility includes GM TH350, TH400, TH250, and 200 transmissions, plus Ford, Lincoln, and Mercury C4 and C6 automatics. That range helps with transmission selection across listed applications, but the supplied facts do not give cable length, safety-switch details, or installation hardware, so those requirements need separate planning.

Skip it if you require a listed cable length and safety switches; the B&M 80675 StarShifter specifies a five-foot cable and safety features.

Consider this YOMIRACING shifter for a TH350 build where switching between linear and ratchet operation is useful. Its broad stated compatibility is helpful, but buyers needing documented cable or switch details should account for those gaps.

#10

10. Replacement 81052 Shifter

• Weight: 3.2 kg
• Handle Material: Stainless Steel
• Material: Stainless Steel

Best for: Modular multi-speed gate setup.

Why it ranks #10: The listing includes TH350 among supported transmissions and describes modular gates, but this is a replacement for B&M 81052 applications, not a clearly complete shifter kit.

A modular gate-plate design is the central feature of this automatic gated shifter, allowing support for compatible two-, three-, and four-speed transmissions. It is listed for B&M 81052 Stealth Magnum Grip Pro Stick applications and includes the TH350 among a broad group of GM transmission fits.

The modular gate system can accommodate different gate plates for compatible two-, three-, and four-speed automatics, letting one shifter configuration address more than a single speed count. For a TH350 build, the listed GM compatibility includes TH400, TH350, TH250, and TH200, along with later GM automatic models. The defined gated positions provide positive shift control, while the stated B&M 81052 application makes model verification important before planning an installation.

Skip it if you want an independently specified complete floor-shifter assembly; the B&M 80675 StarShifter lists its cable and safety switches.

This option fits buyers adapting a compatible B&M 81052 application who want gate plates for different automatic speed counts. Confirm the exact shifter model and transmission before choosing it for a TH350 installation.
