SLP Billet Aluminum Power Dome™ Heads for the Polaris 900 substantially improve combustion efficiency without radically increasing compression. This increased efficiency provides maximum horsepower with less chance of detonation. Delivering an additional 3 horsepower peak with better throttle response makes these heads a great compliment to any engine combination. Features individual interchangeable combustion chambers (domes) for different compression ratios for use in low or high altitudes and easier service. *Does not require any modification to the ECU
