About this product
Upgrade your two-stroke engine with the Prox Cast Piston Kit. Designed for performance and reliability, this piston kit offers enhanced stability and improved thermal characteristics, ensuring your engine runs at its best. Prox pistons are engineered to meet or exceed OEM specifications, providing a direct fit and reliable performance.
Description
The Prox Cast Piston Kit is manufactured using gravity casting with a high-silicon aluminum alloy. The 18% silicon content reduces thermal expansion, contributing to the piston's stability and longevity. Specifically designed for two-stroke engines, these pistons are suitable for both cast iron and Nikasil cylinder bores. For Nikasil cylinders, Prox offers a range of oversizes in A/B/C/D gradings, with each size increasing by 0.01mm in diameter. This meticulous sizing ensures a precise fit, optimizing engine performance and minimizing wear. With a piston diameter of 42.95mm, this standard size A piston kit will help restore or enhance your engine's power and efficiency. Rely on Prox for quality and performance.
