Winter rides can be some of the best of the year, until frosted glass, numb fingers and cold feet send everyone home early. This in-dash cab heater for the 2026+ Polaris RZR XP S and XP S 4 fits into the dash, so it doesn't steal leg room, and uses heat from the engine's cooling system to warm the cab and clear the windshield.

- Adjustable fan speeds and 360° adjustable vents
- Two dedicated defrost vents with hoses
- Built-in shutoff valve

Defrost That Keeps the View Clear
The two defrost vents aim warm air at the windshield to fight fog and frost, and the hoses and heater parts tuck under the dash so the install looks factory.
Heat That Builds as You Ride
Because the heater runs on engine coolant, the air gets warmer as the machine reaches operating temperature, and the hoses are rated for harsh winter cold and high engine heat.
Optional: Quick-Start Flow Valve
The flow valve sends coolant to the heater core while the engine is still cold, then opens automatically at operating temperature so coolant flows through the radiator as normal. It gets you heated air about twice as fast.
Optional: Idle Flow Pump
At idle or low speed the stock water pump moves little coolant, so the heater cools off. The idle flow pump keeps coolant moving and can warm the heater in under 30 seconds. Choose both for the quickest heat when you are slow or stopped.
Which Options Should You Choose?
- Heater only: fine for riders who keep moving at trail speed most of the day
- Add the flow valve: best if you want warm air soon after a cold start
- Add the idle pump: best for slow technical riding, hunting or plowing, where the engine spends a lot of time at idle
- Both: the fastest heat in every situation
Getting the Most Heat
A heater can only warm the air it can hold on to. With an open cab, most of the heat blows straight out the sides, so even a partial enclosure, like a windshield and roof, makes a noticeable difference. Aim the 360° vents at hands and feet first, then switch air to the defrost vents when the windshield starts to fog.

Who It's For and What Pairs Well
For RZR XP S owners who ride in cold weather. A heater works best in a closed cab, so pair it with upper doors from 2026+ RZR XP S doors, a roof from 2026+ RZR XP S roofs and a full windshield from RZR XP S windshields.
