ACL Chevy V8 4.8/5.3/5.7/6.0L Race Series Standard Size Main Bearing Set - CT-1 Coated

You get a full set of main bearings in this kit, which means one box handles the critical bottom-end component for your engine rebuild. These ACL Race Series bearings are built for Chevy V8 LS Gen III and IV engines, covering displacements from 4.8L up to 6.0L. They're a solid option if you're putting together a performance engine or rebuilding a daily driver and want a well-built replacement.

What sets these apart is the CT-1 coating, a dry-film lubricant that helps reduce friction and wear, especially during initial startup and break-in periods. They also feature a 270-degree oil groove, which helps maintain oil flow to the crankshaft even with tighter clearances. Speaking of clearance, these bearings offer an extra 0.001 inches of oil clearance over standard specifications, which is beneficial for engines that see higher RPMs or operate under demanding conditions, helping to ensure adequate lubrication.

This set is for standard size crankshafts. If you've had your crankshaft ground undersize during a rebuild, you'll need a different bearing size. Always double-check your crankshaft dimensions before ordering to ensure you get the correct fitment for your engine build.
