ACL Bearings Race Series Main Chevy Small Block

ACL Bearings Race Series main bearings for Chevy small block engines are tri-metal crankshaft main bearings built for high-performance and racing engines. Also called SBC main bearings or crankshaft main bearing sets, they support the crankshaft under higher RPM and load than standard replacement bearings.

Key Features:

• Tri-metal construction with a high-strength overlay plate. The reduced overlay thickness improves fatigue properties.
• Increased crush for better bearing retention in the housing.
• No flash plating on the back of the bearing. This improves heat transfer through the bearing.
• Race-focused oil grooving to help supply oil to the bearing surface. Groove style varies by part number.
• Engineered for higher RPM operation in performance builds, from street/strip to racing.

ACL is a respected engine bearing manufacturer, known for its metallurgy, design and precision manufacturing. Race Series bearings suit engine builders who want more bearing capacity than a standard replacement bearing offers. Each part number in this line differs in options such as clearance, size and coating. Choose the one that matches your crankshaft and your build specifications.
