Soft Lockers represent the latest generation of quieter traditional locking differentials, although some of the characteristic sound remains. Detroit Locker offers a complete selection of time proven lockers for Jeep vehicles. The patented locking gear mechanism has been the standard in lockers for decades. The 100% axle lock-up & positive gear action is clutchless with nothing to wear out. The trouble-free automatic operation requires no complicated wiring or switches. Detroit Lockers come with a heavy-duty differential carrier to replace the stock unit.

The legendary Detroit Locker began the revolution in performance differentials and still leads the industry today. The Detroit Locker is the most durable and dependable locking differential available.
The Detroit Locker maximizes traction by delivering 100% of the torque to both drive wheels. It is engineered to keep both wheels in a constant drive mode, and has the ability to automatically allow wheel speed differentiation when required.
The Detroit C-Locker is built for C-Clip style axles. The Detroit C-Locker functions with the same technology as the Detroit Locker. The manufacturer's standard C-Clips are used when a Detroit C-Locker is installed.
The Detroit SL Locker or SofLocker is a Detroit Locker with a twist. Accelerator adjustments (drive to coast) are made frequently during normal driving. The Detroit SofLocker makes noise when the drive member reengages the driven members during these adjustments. The Detroit SofLocker employs a pre-load spring pack to keep the drive and driven members engaged and dampens this noise. The pre-load does not affect the speed differentiation function when required while turning corners. The Detroit SofLocker provides the same performance of the Detropit Locker with reduced noise.
No other performance differential has the reputation for delivering traction in mud, snow, rocks and on the track. The choice of professional racers and off-road enthusiasts around the world! The durability of the Detroit Locker is unmatched!
