What does '.010 Oversized' mean for these main bearings?

This means the bearings are manufactured to be 0.010 inches larger in diameter than standard size. This is necessary when your engine's crankshaft journals have been machined down (ground undersize) to remove imperfections or to prepare for performance bearings. Always verify your crankshaft journal size matches the bearing specification.

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

The CT-1 coating is an advanced surface treatment applied to the bearings. It helps to reduce friction, especially during the critical initial engine startup and break-in periods. This coating also aids in improved oil flow and offers an extra layer of wear protection.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit on compatible engines, it is always recommended to consult your specific vehicle's service manual for detailed installation procedures. This includes proper cleaning, lubrication, and torque specifications for the main bearing caps.

Product Details

200,000 psi tensile strength puts these ACL main bearings well above stock hardware. If you're rebuilding a Ford 370, 429, or 460 V8 and need a solid set of race main bearings, these are a popular choice. They're designed to handle the increased stresses of performance applications, ensuring your crankshaft stays properly supported under load. This set is specifically .010 inch oversized, so make sure your crankshaft journals have been machined to match this size.

ACL uses a tri-metal overlay on these bearings, which is a well-known standard for performance engine builds. The CT-1 coating is an advanced surface treatment that helps reduce friction and improve oil flow, especially during initial startup and break-in. This coating also offers a bit of extra protection against wear. These bearings are built to fit a wide range of Ford and Lincoln V8 engines from the late 60s through the mid-70s, covering popular models like the Galaxie, LTD, Thunderbird, and Continental.

When installing these bearings, it's critical to ensure your crankshaft journals are clean and within the specified .010 inch undersize. Always refer to your engine's service manual for the correct installation procedures and torque specifications. Having a clean work environment and proper tools will make the job go much smoother.
