ARB Air Locker Differential for Dodge RAM 1500 (Rear, 31-Spl 9.25in ZF C-Clip Axle) — a pneumatically operated selectable locker that gives you instant, full lock on demand for model years '11–'21. Designed for serious off-road use while preserving normal on-road drivability when unlocked.

This ARB Air Locker replaces the carrier in your 9.25in ZF C-Clip rear axle and uses compressed air to lock the differential gears together, tying both axle shafts to the ring gear for maximum traction when needed. Activation can be made at any speed and the unit returns to open-differential behavior when not engaged, maintaining predictable on-road handling. The kit is supplied with the internal locker, activation switch, solenoid valve, airline and bulkhead fitting. An on-board air compressor is required but sold separately.
