Good To Know

Q: Does this kit include the bearing and pin? A: Yes, the kit ships as a full assembly with the rod, bearing, and pin so a complete lower-end replacement can be performed. Q: Should rods be replaced in pairs or as a set? A: Replacing all rods together is recommended whenever the crankcase is opened so balanced wear is maintained across the assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
