ACL 5M1144H-0.25 High-Performance Main Bearing Set for Mitsubishi 4G63/4G64 6-Bolt Engines

ACL Mitsubishi 4G63/4G64 6 Bolt 1st Gen DSM 0.25mm Oversized High Performance Main Bearing Set

The ACL 5M1144H-0.25 high-performance main bearing set is designed for Mitsubishi 4G63 and 4G64 6-bolt engines used in first-generation DSM applications. These main bearings feature a 0.25 mm oversized specification, making them suitable for crankshafts machined to the corresponding undersize main journal measurement. Verify crankshaft dimensions and bearing clearances before installation to ensure proper fit and engine performance.

Built for demanding automotive applications, this ACL main bearing set supports reliable crankshaft operation in performance-oriented and rebuilt engines. The bearings are manufactured to provide consistent support for the crankshaft while helping maintain accurate oil clearance across the main journals. Proper installation, machining, lubrication, and clearance verification are essential for achieving the intended results.

The ACL 5M1144H-0.25 bearing set is a practical choice for engine builders servicing compatible Mitsubishi powertrains. It is associated with select 1995 through 1998 Mitsubishi Eclipse applications, but exact fitment may vary by engine configuration, model year, and production details. Confirm that the vehicle uses the correct 6-bolt 4G63 or 4G64 engine before ordering.
