SLP STAGE KIT FOR POLARIS 850 MATRYX BOOST

Turn your Boost into a BEAST that snarls and spits fire! Including our Ultra-Lite™ Silencer and Power Shift Clutch Kit™, this kit sheds 6 lbs. of unneeded weight and provides startlingly better performance. The secret that makes this kit such a potent performer is the way our Magnum Force Ultra™ Clutch Weights improve the sled’s shifting efficiency.

Boost the fun factor with this Stage 2 Kit for the Polaris Boost. This kit utilizes a lightweight silencer which reduces weight by 6 pounds and delivers an increase of 2 horsepower. It also includes an SLP Power Dome™ Billet Head for a total gain of 7 horsepower peak with better bottom end and midrange performance. Rounding out this great kit is our Magnum Force Ultra™ Clutch Weights which significantly improve the sled’s shifting efficiency.


This patented weight set (US Patent #11739836 and Patents Pending) transfers the Boost’s impressive horsepower to the ground with precision using our industry exclusive mass profile. Its design delays initial shift, allowing the turbo to spool faster and then shifts aggressively, loading the engine and creating more exhaust heat. This improves boost function and generates more usable power quicker. Make sure you are set when you pull the boost’s trigger with this kit because she’s gonna launch! No fueling changes required.

For a Rowdy combination, choose the SLP Stage 3 kit. Boasting an incredible 21.3 peak horsepower increase combined with wicked throttle response, this package is a performance monster that will claw its way through any terrain you put it up against. Many hours have been spent on the dyno and in the field to optimize this combination and insure maximum reliability and running consistency on pump fuel. This kit utilizes boost and performance changes from the Stage 3 Flash Tun’R’s custom map combined with the combustion efficiency of the Power Dome™ heads and the Dynamic Flow™ of the Lightweight Silencer that also provides 6 pounds of weight savings. All of this coupled with a Power Shift™ Clutch Kit that utilizes patented SLP Magnum Force Ultra™ Clutch Weights to apply horsepower to the snow effectively and efficiently through all throttle, boost and speed ranges. This combination is not just a dyno dream, but is intended to ride day in and day out consistently with maximum reliability. CAUTION! From your first wick of the throttle you are going to be addicted.
