What does '.001 Oversized' mean for these rod bearings?

This means the bearings are manufactured to be 0.001 inches larger in diameter than a standard-size bearing. They are intended for use when the engine's crankshaft journals have been ground down by 0.001 inches to clean them up or correct wear.

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 improve wear resistance, which is particularly beneficial during the critical engine break-in period.

Do these bearings come with installation hardware?

This product is for the rod bearings only. You will need to reuse your existing connecting rod bolts or purchase new ones separately, and ensure the crankshaft is clean and properly prepped before installation.

Product Details

If you're rebuilding a classic Ford or Mercury V8 engine, getting the bearing clearances just right is crucial for longevity. This set of ACL .001 inch oversized rod bearings is designed for the Ford 221, 255, 260, 289, and Windsor 5.0L engines. Getting the right bearing size is key to ensuring proper oil pressure and reducing friction, especially after an engine has been machined or if you're dealing with a worn crankshaft.

These bearings feature ACL's CT-1 coating, which is a dry film lubricant designed to reduce friction and improve wear resistance. This is particularly helpful during the critical break-in period. The .001 inch oversize means they are intended for use when the crankshaft journals have been ground down by .001 inches to clean them up or correct wear. ACL is a well-known name in performance and racing bearings, and this set is a solid option for anyone looking to build a reliable engine.

This set fits a wide range of classic Ford and Mercury vehicles from the early 60s through the late 60s. Make sure to check the full fitment list to confirm compatibility with your specific application. Proper installation, including checking clearances with Plastigage and ensuring the crankshaft is clean and free of burrs, is essential for these bearings to perform as intended.
