About this product
About this product
Upgrade your two-stroke engine with the Prox Cast Piston Kit. Designed for optimal performance and reliability, this piston kit delivers improved stability and reduced thermal expansion, ensuring a longer lifespan for your engine. Prox pistons are engineered to meet or exceed OEM specifications, providing a seamless fit and enhanced power.
Description
The Prox Cast Piston Kit is crafted using a gravity casting method with a high-silicon aluminum alloy, containing approximately 18% silicon. This significantly decreases thermal expansion, improving the piston's durability under high-stress conditions. Specifically designed for two-stroke engines with both cast iron and Nikasil cylinder bores, Prox offers a range of oversizes graded in A/B/C/D sizing, each increasing by 0.01mm in diameter, allowing for precise fitment during engine rebuilds. The piston features a moly-coated skirt for reduced friction and increased wear resistance. Whether you're rebuilding your engine or looking to enhance its performance, the Prox Cast Piston Kit is an excellent choice for enthusiasts and professionals alike. Installation is straightforward, ensuring your engine is back to peak performance in no time.
