• Tri-metal construction: The Race Series bearings use a tri-metal build designed to handle the loads of performance and racing engines.
• Race-focused design: ACL has built Race Series bearings on more than half a century of bearing manufacturing experience.
• Big Block Chevrolet application: Made for Big Block Chevrolet crankshaft main journals.
• Multiple options in the line: The line includes standard and extra-clearance options, CT-1 coated versions, and narrowed-intermediate designs for crankshafts with large fillets. Undersize options are also available.
