ACL Chevy V8 305/350/400 Race Series Standard Size Main Bearing Set - CT-1 Coated

When you're rebuilding a Chevy V8 like the 305, 350, or 400, the main bearings are critical for keeping the crankshaft spinning smoothly. These ACL Race Series bearings are built for demanding use, featuring a CT-1 coating that helps reduce friction and wear. This coating is a notable improvement over standard bearings, especially in high-performance or racing applications where oil film breakdown can be a concern.

ACL uses a well-built overlay material combined with a strong steel-backed structure to ensure these bearings can handle the stress of a performance engine. The CT-1 coating is a thin, hard layer that helps protect the bearing surface from micro-welding and abrasion, which can extend the life of both the bearing and the crankshaft journals. They are manufactured to standard size, so they're a direct replacement for your original bearings if your crankshaft journals are still within factory specifications.

If you're working on a performance build or a restoration where reliability is key, these ACL bearings are a solid option. Make sure to check your crankshaft journals for any wear or damage before installation, as this will affect bearing fitment and performance. Always follow the manufacturer's recommended torque specifications and lubrication procedures during installation.
