Differential Cover

ARBs Air Locker(TM) (R) 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(TM) (R) from any off-road hazards.

Reference Information

Differential Cover, 12-bolt, Nodular Iron, Black Powdercoated, Dana M220, Each

When off-road, encountering obstacles and hazards that could inflict expensive damage to your differential is inevitable. ARB differential covers are made from high-tensile strength nodular iron (tougher and harder than carbon steel); they are engineered to protect the differential and ring and pinion from off-road hazards. Available for a select line of differentials, they are offered in red or black powdercoated finishes.

Features of ARB differential covers include:
• Computer-optimized, cross brace design increases the structural rigidity of the entire axle
• Helps keep the ring and pinion gears meshing on the flat faces of the teeth--greatly increasing ring and pinion life and overall strength
• Top-quality, rare earth magnets on both the drain plug and dipstick collect metallic particles
• Dipstick magnet allows the oil to be checked for tell-tale signs of internal damage
• Prolonged carrier bearing life (especially on high-output vehicles) from improved support of bearing alignment
• Approach/departure angles optimized by angled exterior surfaces that minimize hang-ups
• Unique dipstick/filler cap design allows differential oil level to be adjusted for rotated differential housings
• Low-profile drain plug resists damage from obstacles
• High-strength cap screws (included) are recessed into the cover for impact protection
