Description
The stock cylinder head on your 2009-2010 Polaris 800 Dragon imposes real limits on combustion efficiency and detonation resistance—especially if you’re running any engine modifications. The Starting Line Products Power Dome Billet Head eliminates those constraints by replacing the factory casting with a precision-engineered billet aluminum design that optimizes combustion chamber geometry, giving you measurable horsepower gains without the knock-on issues that plague aggressive tuning. Whether you’re building a stock platform or pushing a modified engine, this head delivers the durability and thermal efficiency required for sustained performance at low altitude.
