ACL Chevy V8 4.8/5.3/5.7/6.0L Race Series Standard Size Main Bearing Set

When you're building or rebuilding a GM LS Gen III or IV V8 engine, the right main bearings are crucial for keeping things running smoothly. This Race Series set from ACL is built for performance, featuring a 270-degree oil groove that helps ensure consistent lubrication, especially under demanding conditions. This design detail, combined with an extra 0.001 inches of oil clearance over standard, is key for high-performance applications where oil flow is critical to bearing health.

ACL uses advanced materials and manufacturing processes to create bearings that can handle the stress of performance engines. These are standard size bearings, meaning they're designed to fit crankshafts that are still within their original factory specifications. If your crankshaft has been machined undersize, you would need a different bearing size. This set is a solid option for anyone looking to maintain or improve the reliability of their LS engine, whether it's for track use or a powerful street build.

This ACL main bearing set fits a wide range of GM vehicles equipped with the 4.8L, 5.3L, 5.7L, and 6.0L LS V8 engines. This includes popular models like the Chevrolet Silverado, Tahoe, Suburban, Corvette, and Express vans, as well as Cadillac Escalades and CTS sedans, and Buick Rainier and LaCrosse models from the mid-2000s through the early 2010s. Always confirm your engine code and vehicle year to ensure compatibility.
