Description
The ProX Piston Kit for Sea Doo RXP RXT 0.50 mm provides an oversize solution for four stroke supercharged engines that require a light overbore to correct cylinder wear or damage. This half millimeter oversize is commonly used when standard bore clearances can no longer be achieved with honing alone. ProX designs this kit to retain OEM style characteristics while correcting cylinder geometry.
- 0.50 mm oversize piston kit for select Sea Doo RXP and RXT four stroke engines.
- Kit supplies oversize piston, ring set, wrist pin, and circlips for one cylinder.
- Constructed from a low expansion, low friction alloy and precision CNC machined for accurate fit.
- Intended to run at appropriate clearances when used in a correctly bored and honed 0.50 mm oversize cylinder.
- Suitable for supercharged applications where strong sealing and durability are essential.
By stepping up to a 0.50 mm oversize, engine builders can rescue cylinders with moderate wear while restoring clean piston to wall clearances. The ProX piston and ring set is designed to handle the elevated pressures and temperatures associated with boosted operation, supporting reliable power delivery. When combined with proper machine work, tuning, and maintenance, this kit can help keep RXP and RXT models performing at a high level.
Careful measurement of bore size, ring end gaps, and clearances is mandatory, and the condition of the crankshaft, rods, and bearings should be confirmed. Replace gaskets, inspect supercharger components, and confirm cooling and lubrication systems are in good order. With a methodical break in, the ProX 0.50 mm oversize piston kit can serve as a robust cornerstone in a Sea Doo RXP RXT engine rebuild.
