ARB’s Differential Cover has been specifically engineered to protect the differential, ring and pinion set, and your ARB Air Locker® from any off-road hazards. The iconic differential covers come in red and black and are a great addition to the already extensive range which exists for the Dana, Chrysler, Ford, and Chevrolet differential housings.


  • High-tensile nodular iron structure protects differential and ring and pinion set from obstacles
  • Computer-optimized, cross-brace design within the differential cover increases the structural rigidity of the axle acting as a truss
  • Approach/departure angle optimized by angled exterior surface
  • Prolonged carrier bearing life due to extra support to the bearing alignment
  • Additional housing strength helps keep the ring and pinion gears meshing on the flat faces of the teeth, extending ring and pinion life and overall maximum load strength
  • Magnet in the end of the dipstick allows the oil to be checked for tell-tale signs of internal damage without removing the cover or draining the oil
  • Low profile drain plug design resists damage from obstacles
  • Combination of the high-filler point and dipstick allows the oil to be checked for water contamination without having to drain the oil
  • Unique dipstick/filler cap design allows differential oil level to be adjusted for customized high driveline angles
  • Cover is powder coated, CNC machined, and clear-coated for a durable, professional, long-lasting finish; all hardware is hardened and plated
  • Tensile-cap screws (supplied) are recessed for protection against obstacles which might damage or loosen the screws
