The PROX Piston Kit (Part Number 01.5600.000) is engineered for high-performance Ski-Doo 593 H.O and 600 ETEC engine applications. Crafted with precision using dedicated tooling and high-quality casting, this piston ensures exceptional durability and consistent performance. Constructed from hypereutectic alloy, it offers increased strength while minimizing thermal expansion, which translates to improved engine stability and longevity.
Each piston features a specialized dual-ring setup, designed to maximize wear resistance and enhance sealing efficiency. The full MOS2 skirt coating provides superior break-in characteristics and reduces scuffing, contributing to the piston’s extended lifespan. An anodized dome surface offers enhanced protection against excessive heat, maintaining optimal compression and preventing thermal damage during demanding rides.
The kit includes everything needed for installation: piston, rings (including high-quality Riken rings for excellent heat transfer and sealing), wrist pin, clips, and a top-end bearing. These components are selected to ensure precise fit and reliable operation, making it an ideal choice for performance enthusiasts and professional mechanics alike. Whether upgrading your existing engine or building a new one, this piston kit delivers consistent performance and durability for demanding snowmobile conditions.
