What is the difference between standard and undersize bearings?

Standard (STD) bearings are meant for crankshaft journals that are still within the manufacturer's specified tolerance. Undersize bearings (like -010, -020) are used when the crankshaft journal has been machined down to correct for wear or damage.

Do these bearings come with a warranty?

ACL typically offers a limited warranty on their engine components. For specific details regarding the warranty coverage and duration for this bearing set, please refer to the documentation provided by ACL or contact their customer support.

What else might I need when installing these main bearings?

When installing main bearings, it's crucial to have a service manual for your specific vehicle. You'll also need proper torque wrenches, assembly lube, and potentially Plastigage to verify bearing clearances. Ensure all mating surfaces are clean before installation.
