ACL Mitsubishi 4G63/4G64 6 Bolt 1st Gen DSM 0.025mm Oversized High Performance Main Bearing Set

This is a set of ACL high-performance main bearings, specifically sized at 0.025mm oversized. These bearings are crucial for the rotating assembly of your engine, supporting the crankshaft and ensuring it spins smoothly within the block. If you're rebuilding or refreshing a Mitsubishi 4G63 or 4G64 engine with a 6-bolt crankshaft, especially from a 1st Gen DSM, these bearings are designed to fit right in.

ACL has a solid reputation for making well-built engine components, and these main bearings are no exception. They're built to handle the demands of performance applications, helping to maintain proper oil clearance and reduce friction. The 0.025mm oversize means they're intended for crankshafts that have been machined down slightly to true them up, ensuring a precise fit and optimal performance after machining. This is a common step when rebuilding an engine to ensure longevity and reliability.

When installing these bearings, remember to always follow the manufacturer's recommended torque specifications and use a quality assembly lubricant. Proper installation is key to getting the most out of these high-performance parts and ensuring your engine runs smoothly for miles to come.
