The best reverse lockout shift knob or adapter depends on your shifter’s thread size, vehicle, and whether you need a complete lever or a knob adapter. The DEWHEL and Mishimoto adapters suit M12x1.25 threaded shifters with reverse lockout collars, while the BARTOO levers are listed for 2013–2021 Subaru BRZ, Toyota 86/GT86, and Scion FR-S applications. A generic alloy option may suit buyers prioritizing simple installation, but its fitment details are limited.

DEWHEL Black Aluminum Adapter
This aluminum adapter has an M12x1.25 thread pitch and is described as a way to clean up the transition between a DEWHEL shift knob and an original equipment lift-up reverse lockout. It is an adapter rather than a full replacement shift lever.
Best for: Drivers with a matching threaded shifter and lift-up reverse mechanism who want to pair it with a DEWHEL knob. It was selected for its clearly stated thread size and specific purpose.
Limitation: The listed details do not specify a broad range of vehicle fitments. Confirm the thread and lockout arrangement before ordering.
BARTOO Black Reverse Lockout Lever
BARTOO lists this billet aluminum lever for 2013–2021 Subaru BRZ and Toyota FT86/GT86 and Scion FR-S models. The part combines the OEM reverse lockout ring and plastic boot holder into one piece, creating a simpler-looking shifter assembly. Its listed dimensions are approximately 4.1 by 6.5 centimeters.
Best for: Owners of the listed vehicles who want an integrated lockout lever and boot holder. The stated applications and combined components make it easier to compare with a separate knob adapter.
Limitation: The application list is specific to the named models and years. Check your vehicle year and shifter configuration rather than assuming universal fitment.
Alloy Gear Shift Lockout Adapter
This alloy shift knob or adapter is described as quick to install and remove: take off the old knob and screw on the replacement. The listing emphasizes a refreshed shifter appearance but does not provide a vehicle application or thread pitch in the supplied details.
Best for: Buyers who want a straightforward screw-on style and can independently verify that the part matches their shifter. It is included as a general option, not as a confirmed fit for a particular vehicle.
Limitation: Fitment information is sparse. Do not rely on the installation description alone; verify thread size and how the part interacts with the reverse lockout.
BARTOO Silver Reverse Lockout Lever
This silver aluminum lever has the same listed applications and approximate dimensions as the BARTOO black version: 2013–2021 Subaru BRZ and Toyota FT86/GT86 and Scion FR-S, at about 4.1 by 6.5 centimeters. It combines the OEM reverse lockout ring with a plastic boot holder.
Best for: Drivers seeking the same integrated design as the black BARTOO option in a silver finish. It was selected for its named vehicle applications and consolidated lever-and-boot-holder design.
Limitation: The listed vehicle years should be treated as the fitment scope. Confirm the exact model and configuration before purchase.
Mishimoto Black Reverse Lockout Adapter
Mishimoto describes this adapter for Subaru or other M12x1.25 threaded shifters with reverse lockout collars. It adapts the shifter for use with a Mishimoto or non-reverse-lockout-compatible shift knob. The listing also mentions Ford applications, but the thread and collar requirements still matter.
Best for: Buyers who have confirmed an M12x1.25 thread and need an adapter to use a knob that does not accommodate a reverse lockout collar. Its stated compatibility is broader than a single named model, but remains conditional on the shifter specifications.
Limitation: The available details do not identify every compatible vehicle or shifter. Verify the thread and collar setup first.
Buying Guide: How To Choose A Reverse Lockout Part
Do you need a lever or an adapter?
A reverse lockout lever is part of the mechanism that lets the driver lift or move the lockout to select reverse. The BARTOO products combine the lockout ring and boot holder. An adapter, such as the DEWHEL or Mishimoto option, is intended to bridge a shifter’s lockout arrangement and a shift knob. Identify which component you are replacing or adapting before comparing products.
How do you check fitment?
Start with the vehicle’s make, model, and year, then confirm the shifter’s thread pitch and lockout design. M12x1.25 is specified for the DEWHEL and Mishimoto adapters, but that measurement should not be assumed for another product. Compare the product’s stated application with your vehicle and inspect your current hardware when possible.
Should appearance influence the choice?
Finish and design matter after mechanical fitment is established. The BARTOO levers are offered in black and silver in the supplied listings, while the adapter options are listed in black. Choose based on the appearance you want, but do not treat color or material as proof of compatibility.
What should you confirm before installation?
- Whether the listing describes a lever, knob, or adapter.
- The shifter thread pitch, if the part screws onto a threaded shifter.
- Whether your setup uses a lift-up reverse lockout collar.
- Whether the product’s listed vehicle years match your vehicle.
- Whether the boot holder or other existing components need to be retained.
Frequently Asked Questions
What does a reverse lockout adapter do?
It adapts a shifter with a reverse lockout collar so it can work with a shift knob that is not designed for that lockout arrangement. Check the specific product’s stated thread and application requirements.
Are the BARTOO levers universal?
No universal fitment is stated. The supplied listings name 2013–2021 Subaru BRZ, Toyota FT86/GT86, and Scion FR-S applications.
Do the DEWHEL and Mishimoto adapters use the same thread size?
Both list an M12x1.25 thread requirement. That shared specification does not establish compatibility with every vehicle or lockout setup.
Can I choose an adapter by appearance alone?
No. Confirm the thread, vehicle application, and lockout configuration first. Appearance is a secondary choice once fitment is established.
What if a product does not list my vehicle?
Do not assume it fits. Check the shifter’s measurements and lockout design, and seek fitment confirmation before selecting a product with limited application details.
