What is the difference between standard and undersize bearings?

Standard bearings are designed to fit crankshaft journals that are still within their original factory specifications. Undersize bearings, often indicated by numbers like -010 or -020 in their part number, are used when the crankshaft has been machined down to correct for wear or damage.

Do these bearings come with assembly lube?

This set includes the main bearings themselves. It is highly recommended to use a quality engine assembly lubricant when installing new bearings to ensure proper initial lubrication and prevent damage during engine startup.

What V8 engines do these bearings fit?

These ACL main bearings are specifically designed for Gen 3 V8 engines, including the 4.8L, 5.3L, 5.7L, and 6.0L displacements commonly found in Chevrolet vehicles.
