ARB Air Locker RD197 for AAM 9.25 & 9.5 Differential, 33 Spline, Select Chevy, GMC, Dodge, Ram 1982-2019

Fits select 1982-2019 Chevrolet, GMC, Dodge, Ram, and Hummer H2 vehicles (AAM 9.25 / AAM 9.5 differentials).

The ARB RD197 Air Locker provides 100% traction on demand, allowing you to transition from a conventional open differential to a fully locked axle at the flick of a switch. This pneumatically operated system uses compressed air to lock the internal differential gears, preventing the axle shafts from turning independently and ensuring both wheels maintain constant rotation with the ring gear. When disengaged, it maintains factory on-road drivability and prevents unnecessary driveline wear.

Engineered for extreme reliability, the RD197 features a two-piece design for maximum strength and a steel-reinforced, elastomer-bonded annular seal capable of withstanding extreme temperature ranges. The patented timed locking mechanism ensures rapid engagement and fast unlocking when you need to return to highway speeds.
