How many pistons do I need to order?

This listing is for a single piston. You will need to order one piston for each cylinder in your Sea-Doo RXP's engine. Consult your service manual for the exact number of cylinders.

What does the 100.5MM bore size mean?

The 100.5MM bore size indicates the diameter of the piston. This is often an oversized dimension, meaning the engine's cylinders would need to be bored out to this specific size to achieve a proper fit and optimal compression.

Is this piston compatible with all Sea-Doo RXP models?

This piston is designed for Sea-Doo RXP models, but it is important to verify the specific bore size and engine requirements for your model year. The 100.5MM size suggests it's for a specific build or modification.

Product Details

This listing gets you one JE Pistons forged piston, designed for your Sea-Doo RXP. It features a 100.5MM bore size, which is a common upgrade size for those looking to rebuild or enhance their Sea-Doo's engine. JE Pistons are well-known for their strength and reliability, making this a solid choice for anyone needing a replacement or performance piston.

Forged pistons like these are built to handle higher stresses than cast pistons, making them ideal for performance applications or when rebuilding an engine that demands durability. The 100.5MM size means it's intended to be used in an engine that has been bored out to this specific dimension, often as part of a performance build or to correct wear in the cylinder wall. JE Pistons uses advanced manufacturing techniques to ensure each piston is well-made and ready to perform.

Remember that this piston is sold individually, so be sure to order the correct quantity for your engine. Also, please note that this part is not CARB approved and cannot be shipped to California.
