Specs At A Glance

Good To Know

Q: Does this piston need a bored cylinder to install? A: Yes, a .040 overbore piston requires the cylinder to be bored and honed to the matching diameter. Have the machine work completed before assembly.

Q: Will this fit a factory stock bore? A: No, it is sized for an overbored cylinder and will not fit a stock bore. Confirm the cylinder has been machined to the correct clearance.

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