Piston Kits

What Is The Difference Between Pistons?
 
WSM Performance Pistons
Cast Piston. Individual kits include one piston, rings, clips and wrist pin.
Complete kits include all pistons, rings, clips, wrist pins, gasket kit & top end bearings.

Available in Original Series and Platinum Series kits. Original Series pistons are made to exact OEM specifications. 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. Piston walls are treated with a nonabrasive coating which reduces heat and friction for extended life.

Pro X Performance Pistons
Cast Piston. Individual Piston Kits include one piston, rings, clips and wrist pin.
Complete kits include all pistons, rings, clips, wrist pins and top end gasket kit.

ProX pistons are precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese engine manufacturers. ProX Piston Kits are a first class solution to replace the original piston in your Personal Watercraft. Designed to be a direct OEM replacement piston. Replacement rings fit both factory & ProX pistons. Can be used along with original factory piston meaning you can just replace one piston if you wish.

Wiseco Performance Pistons
Forged Piston. Individual Piston Kits include one piston, rings, clips and wrist pin.
Complete kits include all pistons, rings, clips, wrist pins and top end gasket kit.

Quality begins with a forging. Castings are porous and weak, Hypereutectic pistons are merely a cast piston with an increased silicon content. Although slightly better, they are not nearly as strong as forgings-which are pressed into shape with a 2000 ton press. Wiseco starts with certified extruded bar stock and forges our pistons in-house with the world's most advanced forging presses. Most aftermarket piston companies do not make their own forgings and therefore cannot achieve the level of quality control that Wiseco demands.
