Differential Covers


WFO Concepts Heavy Duty Differential Covers:

  • Diff covers are cast in one piece from A356.2 aluminum
  • Cast in the USA
  • Heat treated for added strength
  • Aluminum dissipates heat/Cast iron holds heat (that’s why you have an aluminum differential cover but cook with cast iron)
  • Keeping your differential cool reduces damage to your bearings
  • The diff covers are 3/8” thick
  • Top flange is ½” thick
  • Bottom flange is 1” thick
  • We have countersunk the bottom bolts to reduce having the bolts catch or shear off
  • We provide all stainless steel hardware including fill plug and magnetized drain plug
  • We drill an overfill guide hole
