Prox Cast Piston Kit - 39.47mm

Upgrade your two-stroke engine with the Prox Cast Piston Kit, designed for optimal performance and durability. Crafted from high-quality aluminum alloy, this piston kit ensures reliable operation and improved engine efficiency. Experience the difference a precision-engineered piston can make in your machine's power and longevity.

Description

The Prox Cast Piston Kit is engineered with designs often mirroring OEM configurations, enhanced where possible by Prox engineers for superior performance. Manufactured using gravity casting with an aluminum alloy containing approximately 18% silicon, these pistons offer exceptional stability and reduced thermal expansion. This silicon content is crucial, providing dimensional stability under high operating temperatures. Specifically designed for two-stroke engines, Prox pistons are suitable for both cast iron and Nikasil cylinder bores. For Nikasil cylinders, the kit is available in multiple oversizes (A/B/C/D), each incrementing by 0.01mm in diameter, ensuring a precise fit for your specific engine requirements. The moly coated skirt provides improved wear resistance and reduced friction.
