Description Part Numbers
 

Detroit Lockers are well known for being one of the most durable and dependable differential lockers available thanks to their heavy duty construction and simple, yet very effective design. They provide 100% traction to both wheels at all times while still allowing for wheel speed differentiation on the street or other high-grip terrain. The Detroit Locker has been around since 1941 and has stood the test of time to reach legendary status with off-road enthusiasts, hot rodders, and drag racers.



The Detroit Locker comes in No Spin, Soft Locker, N Locker, and C Locker designs to work with numerous axle and gear combinations. While they may look different, each one functions in the same way - as depicted in this video.


Selecting the right locker model is easy using the detailed locker application table below. All of the currently available Detroit Locker models are listed according to the vehicle(s) for which they are compatible. Simply find your vehicle in the list and locate the Detroit Locker part number in the far right column and select it from the pull-down menu above. In some instances you will need to know what type of axle your vehicle has and if you need help finding this information you can call or email us to find out.
