ACL Race Series. Heavy-duty performance bearings, identified by the H in the part number. Designed for high-load and boosted applications.

0.25mm Undersize. For a crankshaft that has been reground 0.25mm below standard. Measure your journals before ordering — fitting an undersize set to a standard crank will leave the clearance far too tight.
