WSM Performance - Yamaha Waverunner Individual Piston Kits

WSM Yamaha Individual piston kits include one piston, rings, clips & wrist pin.

Original Series Pistons are made to exact OEM specifications and can be used along with original factory piston meaning you can just replace one piston if you wish.

Platinum Series Pistons are made of high strength hardened aluminum designed to prevent skirt and ring groove breakage. Platinum piston walls are treated with a nonabrasive coating which reduces heat and friction for extended life.
