DSM/EVO 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.

  • Machined 4140 pre-hard alloy steel
  • Direct bolt-in
  • ARP 8740 fasteners included

Please note... If product is not listed as in stock, there may be a lead time of up to 8 weeks. Please contact via email with any questions regarding lead times on specific products. As we are a small operation, it is tough to keep everything in stock, and we typically only run a batch of something if there are a few backorders placed. With that being, said, we do try our best to run extras, and intend to stock everything as soon as capacity allows. Thanks for everyone's understanding and patience!
