Good To Know
Q: What does Size C indicate? A: Size C is a factory tolerance grade meaning the piston is slightly larger than nominal to ensure proper clearance in a standard bore cylinder.
Q: Can this kit be installed without machining? A: Yes, because it is a standard bore piston kit, it fits directly into a stock cylinder that is within wear limits.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
