Description
Stock pistons wear out—especially in high-RPM trail and racing conditions—leading to loss of compression, power, and reliability. The Wiseco 2435M07050 replaces worn internals with precision-engineered components that restore your Ski-Doo Mach Z’s performance while withstanding the demands of both aggressive trail riding and competitive racing. This complete kit arrives with rings and circlips, eliminating the need for separate purchases and simplifying your rebuild process.
Built from high-silicon alloy, this piston delivers superior strength and thermal stability, meaning better heat dissipation during extended riding sessions and consistent power delivery across your RPM range. Whether you’re pushing your sled hard on the track or cruising technical terrain, you’ll feel the difference in throttle response and overall durability.
