About this part

Product Details

If you're rebuilding a Chevrolet V8 engine, especially one with a 4.8L, 5.3L, 5.7L, or 6.0L displacement, these ACL Race Series main bearings are a solid choice. They're designed to handle the demands of performance builds and offer a .10 inch oversize fit, which is crucial when the crankshaft journals have been machined down during a rebuild.

ACL has been around for a while, and their Race Series bearings are well-built with a focus on durability. They use a tri-metal material that's known for its strength and ability to handle higher loads and temperatures compared to standard bearings. This means they can stand up to more aggressive driving and the increased stress that comes with a performance engine build. The .10 inch oversize is important because it ensures a proper, snug fit on a crankshaft that's been ground undersize, restoring the correct oil clearance and bearing surface.

This set includes the main bearings needed for your engine rebuild. Make sure to check your crankshaft's specifications to confirm the correct undersize needed before ordering. Proper installation, including cleaning and correct oil clearances, is key to getting the most out of these bearings.
