This ACL Race Series main bearing set (MPN 5M1144H-.25) fits select 1971-2006 Mitsubishi, Dodge, Plymouth, Eagle, and Hyundai models equipped with the 4G63 or 4G64 6-bolt engine.

This set is 0.25mm oversized (approximately .010" thicker), specifically designed for engines where the crankshaft main journals have been reground. ACL Race Series bearings utilize a tri-metal construction—combining a steel backing with a lead-tin-copper overlay—to offer superior fatigue strength and embeddability compared to standard replacement bearings.
