What does '0.010 inch oversize' mean for these bearings?

This means the bearings are slightly larger in diameter than standard size. They are designed to be used when the engine's crankshaft has been machined down by 0.010 inches to account for wear or to achieve specific clearances.

What is the material construction of these ACL Race Series bearings?

These bearings feature a tri-metal construction. This design provides a good balance of durability and the ability to conform to the crankshaft, helping to ensure proper oil film and reduce wear.

Are these bearings suitable for a stock rebuild or a performance build?

The Race Series designation and tri-metal construction suggest these bearings are well-suited for performance applications or more demanding rebuilds where durability and consistent oil clearance are important.

Product Details

ACL has been in the bearing game for a long time, and their Race Series bearings are made with a specific tri-metal construction. This means they're designed to provide a good balance of strength and conformability, helping to protect your crankshaft journals. Since these are a 0.010 inch oversize set, they're intended for use when your crankshaft has been machined down to match this size, ensuring a proper fit and oil clearance. This is a common step when rebuilding an engine to correct wear or to achieve specific performance clearances.

This set includes the main bearings needed for your Chevrolet V8. Remember to always consult your engine's specific service manual for the correct installation procedures and torque specifications when installing new bearings.
