What is the CT-1 coating and why is it important?

The CT-1 coating is a dry-film lubricant applied to the bearing surface. It helps to reduce friction and wear, especially during the engine's break-in period, contributing to a longer bearing life.

Are these bearings for a stock or performance engine build?

These are high-performance main bearings designed for demanding engine builds. They feature a tri-metal overlay and a special coating to handle increased stress and heat.

What does 'Standard Size' mean for these bearings?

Standard size bearings are meant to be used with a crankshaft that is still at its original factory diameter. If your crankshaft has been machined undersize due to wear or repair, you will need to select an appropriate undersize bearing set.

Product Details

When you're rebuilding a Ford 351 Cleveland engine, the right bearings make all the difference. These ACL main bearings are built to handle the demands of high-performance applications, offering a solid option for your build. They feature a special CT-1 coating, which is a dry-film lubricant that helps reduce friction and wear, especially during the critical break-in period. This coating is a notable step up from standard bearings, giving you more confidence in the longevity of your engine.

ACL uses a tri-metal overlay on these bearings, which is a well-built combination of materials designed to conform to the crankshaft journal while still offering excellent load-carrying capacity. They are manufactured to standard size, meaning they're intended to be used with an undamaged, factory-spec crankshaft. If your crankshaft has been machined, you'll need to select the appropriate undersize bearing set.

This set fits a wide range of Ford and Mercury V8 engines from the late 60s through the mid-70s, including popular models like the Ford Mustang, Torino, and Mercury Cougar. Make sure to check the full fitment list to confirm compatibility with your specific vehicle. When installing, always follow the manufacturer's recommended torque specifications and lubrication procedures to ensure optimal performance and durability.
