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

'.001 Oversize' refers to the bearing's dimensions relative to a standard size. These bearings are precisely 0.001 inches larger in diameter than a standard bearing. This is crucial when your engine's crankshaft has been ground down by 0.001 inches during a rebuild, ensuring the correct, tight clearance between the bearing and the crankshaft journal.

What is the benefit of ACL Race Series bearings?

The ACL Race Series bearings utilize a specialized overlay material that is formulated to withstand the higher pressures and temperatures typically found in performance-oriented V8 engines. This construction aims to provide improved durability and consistent performance under demanding conditions.

Do these bearings come with installation hardware?

This product is a set of rod bearings only. Installation hardware, such as new connecting rod bolts or nuts, is not included and should be sourced separately if needed for your engine rebuild.

Product Details

When you're rebuilding a classic Chevrolet V8, getting the internal engine components right is key to a long-lasting, powerful build. These ACL Race Series rod bearings are specifically made for the 396, 402, 427, and 454 cubic inch V8 engines. They come in a .001 inch undersize, which is perfect for use with a crankshaft that's been ground to match this specific size during an engine rebuild. This ensures a tight, consistent oil clearance for optimal lubrication and performance.

ACL has been making engine bearings for a long time, and their Race Series is built for demanding applications. They use a special overlay material that's designed to handle the pressures and heat found in performance V8s. The goal here is to provide a solid, well-built bearing that can stand up to the rigors of regular driving and occasional spirited use. Getting the bearing clearance just right is critical for engine longevity, and these .001 undersize bearings help you achieve that precision when you're working with a machined crankshaft.

This set includes rod bearings for your Chevrolet V8. If you're in the middle of a full engine overhaul, remember to check all your other bearing clearances, including main bearings and camshaft bearings, to ensure everything is within spec. Proper installation, including thorough cleaning of all parts and correct oiling procedures, is essential for these bearings to perform as intended.
