Wiseco 40108M10100 Forged Piston Kit 101.00mm Bore 10:1 Compression Sea-Doo

The Wiseco 40108M10100 is a high-performance forged piston kit designed for Sea-Doo RXP, RXP-X, RXT, and RXT-X personal watercraft. Featuring a 101.00mm bore, this kit is engineered specifically for Sea-Doo supercharged engines and delivers a 10:1 compression ratio for enhanced power output.

Wiseco is the only aftermarket piston manufacturer in the United States that produces pistons strictly using the forging process. Starting with aerospace-grade aluminum, the forging process compresses the material's molecules, increasing the density of the aluminum and aligning the grain flow of the alloy — resulting in superior resistance to impact, fatigue, and thermal stress in demanding marine environments.

Key Features:

• Designed for each specific engine application and built to the tightest tolerances for the ultimate combination of performance and strength
• Forged from high-silicon, low-expansion aluminum for superior strength, reduced weight, improved heat transfer, and longer life — with a diamond-turned finish from CNC computer-controlled turning centers for a perfect finish with no size variation
• Engineers utilize the latest 3D design techniques and finite element modeling software to ensure the highest strength and lightest weight for each application
• 0.50mm oversized bore for use during engine rebuilds requiring cylinder boring
• Forged pistons are tougher and more durable than cast pistons, able to stand up to the abuse that high-performance motorsport applications require
• Kit sold individually and includes precision-matched piston, rings, and circlip

Wiseco's state-of-the-art computerized manufacturing facility is dedicated to supplying both the high-performance racer and recreational enthusiast with the finest forged piston available in today's marketplace. Whether you're rebuilding after a hard season or pushing your watercraft to its limits, the 40108M10100 delivers the reliability and performance Sea-Doo owners demand.
