Product details
SLP's Power Dome billet cylinder head set designed specifically for the Polaris Patriot Boost engine. Sold as a complete set, all elevations.
On snow our testing puts the Boost head at 5–6 hp; SLP's figure is +5 hp peak with broader performance at all throttle positions and a very responsive bottom end. It raises the detonation threshold and adds cylinder-head and engine cooling, so we recommend it as a supporting mod or on its own at any power level, stock to heavily modified. It is a versatile, consistent power gain with no downsides on the Patriot Boost. Pair it with the A2D Patriot Boost clutch kit ($569) and the A2D Matryx Boost 3-stage tune ($475).
Fitment. 2022–2027 Polaris Patriot Boost Matryx, all models (RMK, Khaos, Slash, VR1, Switchback Assault). Not for the naturally aspirated 850 (SLP 12-850) or the 9R (SLP 12-900).
