Detroit Locker 187SL47A by Eaton Performance for 29 Spline AMC Model 20 Axle with 3.08 and Numerically Higher Gear Ratio

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 Sof Locker is a Detroit Locker with a twist. Accelerator adjustments (drive to coast) are made frequently during normal driving. The Detroit Sof Locker makes noise when the drive member reengages the driven members during these adjustments.

The Detroit Sof Locker 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 Sof Locker 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! Legendary Durability Ultimate Performance Fully Automatic Locking Action 100% Locking No Individual Wheel Spin-Out Maintenance Free Proven Design.
