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.
