What is the difference between Race Series and standard ACL bearings?

ACL Race Series bearings feature a specialized tri-metal overlay designed to withstand higher loads and temperatures common in performance engines. Standard bearings are typically made for everyday driving conditions.

Do these bearings come with assembly lube?

This set includes the rod bearings only. You will need to purchase a high-quality assembly lubricant separately to ensure proper lubrication during engine assembly.

What if my crankshaft journals are worn or machined?

These are standard size bearings. If your crankshaft journals have been machined undersize due to wear or to prepare for larger bearings, you will need to select the corresponding undersize bearing set from ACL.

About this part

Product Details

When you're building or rebuilding a performance Chevrolet V8, especially one with a 396, 402, 427, or 454 cubic inch engine, the bearings are a critical component. These ACL Race Series conrod bearings are built with a special overlay that's designed to handle the higher loads and temperatures found in performance applications. They feature a tri-metal construction with a steel-backed overlay that offers excellent strength and durability.

ACL uses a unique extrusion process for their bearings, which helps create a more uniform and consistent overlay. This means you get reliable performance and reduced friction, even under demanding conditions. The standard size (STD) ensures a precise fit for your crankshaft journals, assuming they are within factory specifications. If your crankshaft has been machined, you'll need to select the appropriate undersize bearing.

These bearings are a solid choice for anyone looking to get the most out of their big-block Chevy engine. They're designed to work well with a variety of oil types and are a popular option for both street performance and track use. Make sure to check your crankshaft journal dimensions and follow proper installation procedures, including torque specifications and assembly lube, for optimal results.
