What does 'standard size' mean for these main bearings?

Standard size bearings are meant to be used when your crankshaft journals are at their original, factory-specified diameter. If your crankshaft has been previously machined undersize, you would need a different size bearing set.

What is the benefit of the CT-1 coating?

The CT-1 coating on these ACL bearings helps to reduce friction between the bearing and the crankshaft journal. It also aids in oil retention, which is important for proper lubrication and wear resistance, especially during engine break-in.

Are these bearings suitable for high-performance or racing engines?

Yes, the ACL Race Series is designed with performance in mind. The CT-1 coating and overall construction are intended to handle the increased demands of performance and racing applications, in addition to standard rebuilds.

About this part

Product Details

When you're rebuilding or refreshing a Chevy small-block V8, the main bearings are critical for keeping everything spinning smoothly. This set from ACL Race Series is built for engines displacing between 262 and 350 cubic inches, covering a wide range of popular Chevy V8s. They're standard size, meaning they're meant to be used with an un-machined or freshly machined crankshaft that's back to its original diameter. The CT-1 coating is a notable feature that helps reduce friction and wear, especially during the crucial break-in period and under demanding conditions. This coating also aids in oil retention, which is key for keeping those main journals lubricated.

This set is a solid option for anyone looking to put a reliable engine back on the road or track. Make sure to check your crankshaft dimensions and consult your engine rebuild manual for proper installation procedures and torque specifications.
