Other differential covers are large and bulky resulting in lubricating oil being flung off the ring gear. BD's design deflects the oil back onto the ring gear and into the pinion gear for cooler longer life.

  • BD's Cast to Cool Differential Cover
  • Engineered cover design keeps oil on the gears
  • Extra capacity sump located at bottom for gears to pick up oil
  • Internal and external cooling fins
  • Stainless steel allen head cap bolts, fill plug
  • Magnetic drain plug

    You will get an increase in fluid capacity so it will take longer for the rear diff to come to temp.
