ACL Mitsubishi 4G63/4G64 7 Bolt 2nd Gen DSM and EVO I-IV Standard Size High Performance w/ Extra Oil

The ACL 5M1186HX-STD is a high-performance main bearing set designed for Mitsubishi 4G63 and 4G64 7-bolt engines used in second-generation DSM applications and Mitsubishi Evolution I through IV models. Manufactured to standard size specifications, these bearings are intended for engines with standard-dimension main bearing journals and provide a dependable foundation for street, performance, and competition-oriented engine builds.

ACL HX-Series bearings feature an enhanced bearing design with additional oil capacity to support improved lubrication under demanding operating conditions. The construction is engineered to promote consistent crankshaft support, efficient oil distribution, and reliable performance through elevated engine speeds and increased loads. The standard-size configuration makes this set suitable for rebuilds where the crankshaft and block remain within original factory specifications.

This automotive replacement and performance component is supplied as a complete main bearing set for the applicable engine configuration. Confirm crankshaft journal measurements, block condition, bearing clearance requirements, and engine application before installation. Proper cleaning, inspection, lubrication, and professional installation procedures are essential for achieving the intended service life and performance. The set is listed for fitment with select 1995–1998 Mitsubishi Eclipse applications and should be matched to the exact vehicle, engine, and model configuration.
