What is the CT-1 coating on these bearings?

The CT-1 coating is a special surface treatment applied by ACL. It's designed to help reduce friction between the bearing and the crankshaft journal, which can improve wear resistance and potentially help maintain oil pressure under demanding conditions.

Are these bearings suitable for a daily driver or only for racing?

While these are part of ACL's Race Series and well-built for performance, the CT-1 coating and standard size make them a solid choice for many applications. They offer improved durability over stock bearings, which can benefit even a street-driven performance engine.

Do I need any special tools or procedures for installing these bearings?

Installing main bearings requires careful attention to cleanliness and proper torque specifications. Always refer to the specific service manual for your engine to ensure correct installation procedures, including checking bearing clearances and crankshaft end play.

About this part

Product Details

When you're building or rebuilding a Chevy V8, especially one destined for the track or serious performance, the main bearings are critical. These ACL Race Series bearings are built to handle the extra stress. They're standard size, meaning they're designed to fit a factory-spec crankshaft, and feature ACL's CT-1 coating. This coating helps reduce friction and wear, which is super important when you're pushing an engine harder than stock.

This set covers a wide range of popular Chevy V8 displacements, from the 262 cubic inch all the way up to the mighty 350. If you're working on a performance build and need reliable main bearing support, this is a solid option. Make sure to follow the manufacturer's installation instructions carefully, as proper bearing clearance and lubrication are key to engine longevity.
