ARB Differential Covers

ARB’s nodular iron Differential Covers have been engineered to protect the differential and ring & pinion from off-road hazards.

Features:

  • Computer optimized cross brace design increases the structural rigidity of the whole axle
  • Additional housing strength helps keep the ring & pinion gears meshing on the flat faces of the teeth, greatly increasing ring & pinion life and overall maximum load strength
  • Top quality, high power neodymium magnets are used in both the drain plug and the dipstick to collect metallic wear particles
  • Magnet location in the end of the dipstick allows the oil to be checked for tell-tale signs of internal damage
  • Prolonged carrier bearing life due to extra support to the bearing alignment
  • Approach/departure angle optimized by angled exterior surfaces
  • Unique dipstick/filler cap design allows differential oil level to be adjusted for customized high driveline angles

Available for:

  • Dana 35
  • Dana 44 (except Aluminum)
  • Dana 50/60
  • Chrysler 8.25″
  • Ford 8.8″

TA Performance Girdles

Made from 356-T6 cast aluminum, these covers are actually a girdle incorporating a reinforced crossbar. The crossbar houses the load bolts that apply pressure to the bearing caps. This feature, along with the thick casting, prevents bearing cap deflection under severe loads. Which in turn greatly reduces or eliminates (in most cases) bearing cap fatigue and failure. Specifically designed to add support to the bearing caps under severe loads and acceleration, these girdles substantially strengthen the rear end. They also add fluid capacity, which helps to lower the fluid temperature. Comes with drain and fill plugs for easy maintenance.

  • All TA Girdles are made of 356 aircraft grade aluminum, heat treated to T6 specifications. Each cover is then stress relieved.
  • All Girdles incorporate a Fill Port and a Drain Port for ease of servicing.
  • All Girdles incorporate 2 load bolts with swivel “feet” for supporting the bearing caps.
  • All Girdles increase fluid capacity approximately 1/2 pint.
  • All Girdles show an average decrease in operating temperature of 15 degrees.
  • Weighs about 9.5 lbs.
  • Improves Undercarriage Appearance.
  • Comes complete with girdle, bolts, gasket, and instructions
