Good To Know

Q: Does this piston drop into a stock cylinder? A: No, a .010 overbore piston requires the cylinder to be bored and honed to 72.25mm first. Confirm your cylinder has enough material for the overbore before ordering.

Q: Is a piston kit just the piston? A: A Wiseco piston kit for the Phazer 480 typically bundles the piston with rings, wrist pin, and clips for a complete top end refresh. Verify the contents listed by the seller match what your rebuild needs.

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