Good To Know

Q: Do I need to bore my cylinder for these pistons? A: Yes, .040" oversize pistons require the cylinder to be bored and honed to match before assembly. Confirm your machinist has the pistons on hand to set clearance.

Q: Is this set enough for a full top end rebuild? A: It covers pistons, wrist pin bearings and top end gaskets. Check for any additional seals or fasteners your particular rebuild calls for.

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