Frontline Fabrication Rear Diff Bearing Caps

These bearing caps are machined from 4140 pre-hard alloy steel and are a direct replacement for the bearing caps in the Evo and DSM rear ends. Our girdled diff covers have proven that there is an issue with bearing cap deflection in these rear ends, and these will add a second line of defense alongside the diff covers. These are not a replacement for the girdled diff covers but are a supplement to further increase strength. ARP 8740 fasteners are also provided to replace the low-grade factory fasteners.

*This product does not qualify for discounts at the time. If you have a discount code that will work, we will send an invoice asking for the discounted amount before your order is processed.

All Frontline Fabrication parts have an average lead time if at least 8+ weeks.

The only exception to this is the Frontline Fabrication Ball Bearing Gerotor Oil Pump, as these take 6-10+ MONTHS to make and ship!
