Description
If you’re running Polaris sleds hard, your stock pistons are likely your weakest link—heat and friction rob horsepower and shorten engine life. The WSM Piston Kit replaces worn or damaged pistons with OEM-equivalent or better construction, while the MOS2-coated skirts actively reduce friction and draw heat away from critical components. This kit delivers measurable gains in reliability and performance without requiring custom fabrication.
Each kit includes everything needed for one cylinder and is engineered for direct fitment to your Polaris engine. The improved E-clip design increases durability under high RPM loads, while specially hardened ring grooves resist deformation from aggressive tuning. Order one kit per cylinder you’re rebuilding.
