For the ultimate in performance and looks, our line of Billet machined heads for the Polaris AXYS 850 (Patriot) are the answer to the highest performance as well as pump-gas operation! The Idaho™, purpose built for pump gas, and The Colorado™ which has been optimized for high-octane, high boost.


Both heads offer a ruggedized, through-bolt construction from aerospace-grade aluminum, maximized cooling potential, and the top-tier driveability and consistency that BoonDocker customers have come to expect. We’ve ridden the pump-gas setup, including The Idaho™, and can attest that this is pump-gas perfection.



THE IDAHO™: For BoonDocker turbocharged Polaris Patriot owners, The Idaho head from BoonDocker is the solution to pump gas performance among all aftermarket turbo kits because we’ve strategically engineered a combustion chamber that fully leverages the potential power of the turbocharger kit, at all RPM’s and riding conditions, provides more predictability and control of tuning, while incorporating a ruggedized design and bill-of-materials, specific to the higher demands of a turbocharged engine.


THE COLORADOFor BoonDocker turbocharged Polaris Patriot owners looking for the ultimate in high-octane power delivery, The Colorado™ head from BoonDocker provides both increased performance and strength over the stock head because The Colorado’s™ combustion chamber has been optimized for the demands of high-boost, high-octane, while providing additional horsepower and control and predicitbility of tuning, over the stock head.


NOTE: The Colorado head also has an application for pump-gas above 8,500 feet. Read more in the FAQ's
