Description

When you're pushing your Ski-Doo MXZ800R to its limits, your original pistons won't cut it. This Wiseco kit gives you forged-aluminum reliability and thermal stability that stock components simply can't match—critical when you're running extended high-RPM sessions or aggressive trail conditions. Everything you need for a complete top-end rebuild comes in one box, eliminating the guesswork and compatibility issues that come with mixing brands.

The high-silicone forged material resists thermal expansion and fatigue better than cast alternatives, translating to tighter tolerances and longer ring life. Wiseco engineered these pistons and rings as a matched set—their rings won't perform optimally with competitors' pistons, so you're getting a cohesive system designed to work together from day one.

  • Fitment: Ski-Doo MXZ800R (2008–2011)
  • Material: High-silicone forged
  • Includes: Pistons, rings, wrist pins, circlips, gasket kit
  • Installation: Professional rebuild recommended
  • Ring compatibility: Wiseco-specific only
  • Application: High-performance, extended duty

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
