Specs At A Glance

Good To Know

Q: Do these pistons fit a standard cylinder? A: No, they are .040 inch oversize and require a cylinder bored and honed to match that dimension.

Q: Is anything else needed for the rebuild? A: Rings, wrist pins, clips, and gaskets are typically replaced at the same time, so check your engine kit needs before ordering.

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