Good To Know

Q: Can this .020 piston go into a stock cylinder? A: No, the cylinder must first be bored and honed to the matching 84.50 mm oversize dimension before installation.

Q: How many pistons are in this listing? A: This is a single oversize piston, so a triple-cylinder SUV 1200 rebuild requires three.
