What is the CT-1 coating on these bearings?

The CT-1 coating is a dry-film lubricant applied by ACL. It's designed to reduce friction and wear, offering protection during engine break-in and under high-stress operating conditions.

Are these bearings suitable for a stock engine rebuild?

While these are race bearings, they are standard size and can be used in a stock rebuild if the crankshaft is in factory-spec condition. The CT-1 coating can offer improved protection over standard bearings, especially during the initial run-in period.

What if my crankshaft has been machined?

These bearings are standard size. If your crankshaft has been ground undersize (e.g., for reconditioning), you will need to order the corresponding undersize bearings from ACL to ensure proper clearance.

Product Details

If you're building a performance Ford V8, especially one with the 370, 429, or 460 big block, these ACL race main bearings are a solid choice for the bottom end. They're designed to handle the extra stress that comes with a performance build, whether you're looking for more power or just a more durable engine for heavy-duty use.

ACL has put a CT-1 coating on these bearings. This is a dry-film lubricant that helps reduce friction and wear, especially during the critical break-in period and under high-load conditions. They are standard size, meaning they're meant to be used with a factory-spec crankshaft. If your crankshaft has been machined, you'll need to check the undersize specifications to order the correct bearings.

This set fits a wide range of Ford, Mercury, and Lincoln vehicles from the late 60s and early 70s, including popular models like the F-Series trucks, LTD, Thunderbird, and Continental. Make sure to check the fitment list to confirm compatibility with your specific application.
