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

ACL's Race Series bearings utilize a unique tri-metal construction with a high-performance overlay and a hardened steel backer. This design offers improved strength and wear resistance compared to standard bearings, making them suitable for higher-stress engine applications.

Do these bearings come with installation instructions?

While this set includes the necessary bearings for your engine, it's always recommended to refer to the manufacturer's installation guidelines or a professional service manual for proper installation procedures and torque specifications.

What does 'STD' size mean for these connecting rod bearings?

STD stands for standard size. This means the bearings are intended for use with a crankshaft that has not been machined or ground undersize. It ensures the correct oil clearance when paired with a factory-specification crankshaft.
