ARBs Air Locker engineers have expanded the range of differential covers and are pleased to release new versions of their competition differential cover to suit the Jeep Wrangler JL Sport, Sahara and Rubicon models. These new differential covers are a great addition to the already extensive range which exists for the Jeep Dana differentials. ARBs Differential Cover will protect your differential against the hazards of competition or extreme off-road use. When off-road, it is inevitable that obstacles encountered could potentially inflict expensive damage on your differential. To prevent this, ARBs Differential Cover has been specifically engineered to protect the differential and ring and pinion set and your ARB Air Locker from any off-road hazards.
