Extra Capacity Finned Aluminum Differential Rear Covers
Differential covers come in three finishes, as cast, power coated and polished. We suggest using power coated units because the power coating greatly reduces pitting and corrosion of the aluminum.

Differential Cover Features:

• Increased oil capacity for cooler temperatures
• Sand-cast aluminum with raised fins
• 3/16-inch thick wall construction to add strength to differential housing
• 3/8-inch thick gasket flange will not bend when bolts are tightened
• Machined gasket surface for a secure seal using RTV or factory re-useable gasket
• Oil changes without removing the cover
• All hardware provided, including magnetic drain plug

Don’t forget to order 4 quarts of Royal Purple 85W140 synthetic gear lubricant to complete your installation.

• Fuel Additives
