$188.13

Fits select 1971-2006 Dodge, Eagle, Hyundai, Mitsubishi, and Plymouth models equipped with 4G63 or 4G64 6-bolt engines. These high-performance main bearings are designed for demanding race environments where standard tolerances aren't sufficient.

These are a direct replacement for 6-bolt 1st Gen DSM and early Evolution engines, providing the thermal stability required for forced induction and competition use.
