Good To Know

Q: Does this kit include rings and pin? A: Wiseco piston kits typically include the piston, rings, wrist pin, and clips, but confirm the exact contents before ordering. Q: How do I know if I need a .060 oversize? A: An oversize piston is used after the cylinder has been bored or re-plated to match, so measure your bore before purchase.

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