Good To Know

Q: Do I need to replace the cylinder as well? A: Only if the cylinder bore is damaged or out of spec; this kit is designed for a standard bore cylinder that is within service limits.

Q: What is the difference between Size B and other sizes? A: Size B indicates a piston that is slightly larger than nominal to match a worn bore, but still within standard classification; always verify your cylinder's measurement.

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