What does 'standard size' mean for these main bearings?

Standard size bearings are meant to be used with a crankshaft that is at its original factory dimensions. If your crankshaft has been machined undersize due to wear or damage, you will need to order a set of undersize bearings instead.

What material are these ACL main bearings made from?

These ACL main bearings are constructed from a tri-metal material. This type of material is chosen for its combination of strength, durability, and ability to handle the high loads and friction present in the engine's main bearing journals.

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 on the bearings and crankshaft journals during installation to ensure proper initial lubrication and prevent damage.
