The Main Bearing Set Coated SBC 265/283/302/327 from ACL Bearings is essential for any serious small-block Chevrolet engine build. Whether restoring a classic 265 or enhancing the performance of a 327, these precision-engineered main bearings provide the necessary support for the crankshaft under load. They are designed for enthusiasts who prioritize durability and reliability in their engine builds.
These main bearings feature advanced coating technology that protects against micro-welding, scuffing, and premature wear, especially in high-performance applications. The coating reduces friction during cold starts and break-in, which helps extend bearing life and maintain consistent oil pressure across all five main journals. They are built to strict OEM tolerances while offering superior surface hardness compared to standard uncoated bearings.
Engine builders and mechanics trust ACL main bearings for their compatibility with 265, 283, 302, and 327 SBC blocks. This bearing set is ideal for street performance, vintage racing, and long-term reliability. Proper bearing selection is crucial for achieving optimal performance in both stock rebuilds and high-performance applications.
