Good To Know

Q: Does this kit include bearings? A: Confirm the contents with the listing details before ordering, as kit packaging can vary between production runs. Q: Can I install one rod on its own? A: Rebuilders often replace rods as a set for even balance, so check your service manual for the recommended approach.

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