Specs At A Glance

Good To Know

Q: Are these pistons compatible with the stock cylinder? A: Yes, they are standard bore size B, so they fit directly into the original cylinder without boring.

Q: Do I need to replace the cylinder when installing these pistons? A: Not necessarily; if the cylinder is within service limits, you can reuse it with these new pistons for a cost-effective rebuild.

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