Prox Cast Piston Kit for 2-Stroke Engines

Elevate your 2-stroke engine's performance and reliability with the Prox Cast Piston Kit. Engineered for exceptional durability and precise fitment, this high-quality piston kit ensures your motorcycle runs at its peak.

Description

The Prox cast piston kit is meticulously engineered to meet or exceed OEM specifications, often incorporating design enhancements for superior performance. Crafted through a gravity casting process using an advanced aluminum alloy with approximately 18% silicon content, these pistons offer remarkable stability and reduced thermal expansion. This critical silicon inclusion significantly contributes to the piston's longevity and consistent operation under demanding conditions. Designed for both cast iron and Nikasil cylinder bores, this 2-stroke piston replacement is versatile. For Nikasil cylinders, Prox provides a comprehensive range of oversizes (A/B/C/D), with each grade increasing the 53.95 mm piston diameter by 0.01mm, ensuring a perfect match for your specific engine rebuild needs. Each piston features a durable moly-coated skirt for reduced friction and extended lifespan, while the robust steel ring material guarantees optimal compression and sealing.
