Product Description

The ARB RD187 Air Locker Differential is engineered to provide superior traction for off-road enthusiasts. Designed specifically for the AMC Model 20 rear axle with 29-spline shafts and a 2.73:1 gear ratio, this differential allows for seamless transition between locked and unlocked states. When locked, it delivers 100% traction, ensuring optimal performance in challenging terrains. When unlocked, it functions like an open differential, allowing for normal street driving.

Constructed from high-strength steel, the RD187 is built to withstand the rigors of off-road adventures. Its pneumatic activation system requires an ARB Air Compressor, sold separately, to operate. This differential is compatible with various Jeep models from 1976 to 1986, including the CJ5, CJ7, Wagoneer, Cherokee, and J-10/J-20 pickups. Installation is straightforward with the included hardware and detailed instructions.
