ACL Race Series Rod Bearing Set for Select 1971-2006 Mitsubishi/Dodge, 4G63/4G64 6-Bolt, STD HX Extra Oil Clearance

This ACL Race Series connecting rod bearing set is engineered for high-performance applications on select 1971-2006 Mitsubishi, Dodge, Eagle, Hyundai, and Plymouth models (1.2L, 1.3L, 1.4L, 1.5L, 1.6L, 1.7L, 1.8L, and 2.0L 4G63/4G64 6-bolt engines). Part of the ACL Race Series line, these bearings are designed to withstand the high RPMs and increased loads found in turbocharged or high-compression builds.

The "HX" designation indicates this set provides an extra 0.025mm (0.001") of oil clearance compared to standard "H" bearings. This thinner bearing design allows for increased oil flow to help manage heat and maintain a consistent hydrodynamic film in demanding racing environments. Constructed with a tri-metal design, these bearings feature a hardened steel back, a copper-lead intermediate layer, and a lead-tin-copper overlay for superior fatigue strength and embeddability.
