What does 'Standard (STD) size' mean for these bearings?

Standard size bearings are designed to fit crankshaft journals that are still within their original factory specifications. If your crankshaft has been ground undersize due to wear or previous machining, you would need a different size bearing set.

What is the benefit of a lead-free composite material?

The lead-free composite material is an environmentally safer alternative to traditional bearing materials. It also offers good wear resistance and durability, making it suitable for moderate engine loads.

Does this bearing set include the necessary hardware for installation?

This product is a set of main bearings only. You will need to refer to your vehicle's service manual for specific installation procedures and any additional hardware or sealants that may be required.
