Description

The Ratech 313K is a complete differential installation kit designed for Chevy Corvette models from 1963-1979. This kit includes bearings, crush sleeve, gaskets, hardware, seals, shims, and marking compound.

Ratech emphasizes the superior quality of their shims, which are manufactured in-house using American-made hardened shim stock, not sheet metal. This ensures no gaps in thickness and prevents splitting during performance applications, addressing common issues with non-OEM gear sets and wider tolerances.
