ACL Mitsubishi 4G63/4G64 7 Bolt 2nd Gen DSM and EVO I-IV 0.025mm Oversized High Performance Main Bea

The ACL 5M1186H-.025 high-performance main bearings are designed for Mitsubishi 4G63 and 4G64 7-bolt engines used in second-generation DSM applications and Mitsubishi Evolution I through IV models. These main bearings feature a 0.025 mm oversize specification to support crankshaft journals machined to the corresponding undersize, helping restore proper bearing clearance during an engine rebuild.

Manufactured for demanding street and performance applications, ACL high-performance bearings are engineered to provide dependable load support, consistent oil control, and reliable operation under increased engine stress. The bearing construction and precision manufacturing help promote accurate fitment when used with properly measured crankshaft journals, bearing bores, and clearances. Always confirm the required bearing size and inspect all related engine components before installation.

What's Included: One set of ACL 5M1186H-.025 high-performance main bearings for the applicable Mitsubishi 4G63/4G64 7-bolt engine configuration.

Fitment: Intended for select 1995–1998 Mitsubishi Eclipse applications and other compatible second-generation DSM and Mitsubishi Evolution I–IV vehicles equipped with the applicable 7-bolt 4G63 or 4G64 engine. Vehicle fitment may vary by engine configuration, model year, and crankshaft specification. Verify the engine code, main bearing design, and required oversize before ordering.
