Description
The ProX Piston Kit for Sea Doo RXP RXT Standard is a stock bore replacement piston set for popular supercharged four stroke Sea Doo models. This standard size kit is designed for cylinders that still fall within OEM tolerances and can be renewed with a simple hone. It provides an effective way to restore compression, refine engine smoothness, and maintain factory like behavior in performance oriented watercraft.
- Standard bore piston kit built for select Sea Doo RXP and RXT models using the applicable four stroke engine platform.
- Kit includes standard size piston, ring pack, wrist pin, and circlips for one cylinder.
- Manufactured from a low expansion, low friction alloy and CNC machined for precise geometry and weight balance.
- Developed to run at clearances similar to the OEM piston when combined with a properly inspected and honed cylinder.
- Part of the ProX range of OEM style replacement pistons for personal watercraft and other powersports engines.
Supercharged engines rely heavily on accurate piston fit and reliable ring sealing to handle elevated cylinder pressures. This ProX standard bore kit is intended to deliver those characteristics so that RXP and RXT models can continue to perform as designed. When used alongside correct fueling, cooling, and lubrication, the engine can regain clean idle, strong mid range, and consistent top end performance.
Engine builders should measure cylinder bores carefully, check ring end gaps, and inspect the rotating assembly for wear. Replace all necessary gaskets and seals, verify supercharger and intercooler condition, and follow manufacturer torque and assembly guidelines. With a sensible break in period, the ProX Standard piston kit becomes a solid foundation for a long lasting Sea Doo RXP RXT engine refresh.
