Polaris RZR 4 Heaters

Loading four hunters into a Polaris RZR 4 for a pre-dawn drive to the stand means someone's fingers are going numb before the truck lot even clears. A SuperATV coolant heater fixes that fast, pulling heat straight off the engine and pushing 14,600 BTU through the cab at 135 CFM, enough to keep all four seats warm on a January ride instead of just the driver's knees. That kind of output is why Polaris RZR 4 heaters top the list every November for owners who actually use the extra seats instead of leaving them empty in the garage.

The RZR 4 lineup splits into two heater platforms. Machines built on the XP 1000 chassis (2014-2023) use a coolant-tap heater like SuperATV's, and it will not clear a cab with the optional glovebox subwoofer without the version built for that setup. The newer Pro XP, Pro R, Turbo R and Turbo S crew cabs share a chassis, and Inferno Cab Heaters builds a direct-fit kit for the 2019-current Pro XP crew cab with an 18,000 BTU core and an SPAL blower. We're based in Wisconsin, so we winter our own machines here, and this is personal experience, not catalog copy. Get the wrong platform and the mounting bracket, hose length and dash cutout will not line up. We're the fitment experts.

What Separates a Real RZR 4 Cab Heater From a Dash-Mounted Plug-In

A coolant-tap heater and a 12V plug-in heater are not competing for the same job, and the build quality shows it fast. SuperATV's cab heater uses radiator-grade hoses rated -40°F to 285°F and routes its defrost vents through the dash so they look factory-installed. Inferno's Pro XP kit steps up with an SPAL multi-speed blower, the same fan brand used in OEM automotive HVAC, and the kit carries a 1-year warranty. SuperATV's kit and Inferno's kit each include the mounting brackets and drill templates cut for the RZR 4's specific dash, not a generic UTV shape. The most common install mistake we see is skipping that template and eyeballing the vent hole, which usually ends with a defrost vent aimed at the ceiling instead of the windshield. A cheap 12V unit skips all of that: no coolant tie-in, no defrost routing, only a fan pushing whatever heat a 300-watt element can generate. It installs in minutes, but it is not solving the same problem a crew of four in an open cab actually has. Pair either cab heater with RZR 4 doors or a cab enclosure and the heat stays where you put it instead of blowing out an open door frame.

Polaris RZR 4 Heater Pricing: What You'll Actually Pay

Cab heater pricing runs a real range depending on how much of the cab you want warmed. At the low end, the Greene Mountain 12V swivel-base heater runs $89.95 and gets one seating position warm within minutes of plugging in, no installation beyond mounting the base. The sweet spot for most RZR 4 owners is Inferno's Pro XP Cab Heater with Defrost at $427 to $476, delivering 18,000 BTU, real defrost and a direct-fit 15-minute install with no drilling into unknown territory. At the premium end, SuperATV's coolant heater runs $445.95 to $753.85 once you add the optional quick-start flow valve and idle flow pump, cutting warm-up time roughly in half. If you would rather each of the four seats get its own control instead of one shared cab temperature, the Moose Seat Heater Kit at $94.95 wires directly to the battery with a Hi/Low switch per seat.

The most common warranty is between 3 to 6 months, but Everything Polaris RZR does offer extended 1- and 2-year warranties on all products if that is something you are interested in — you can add the extended warranty right at checkout. Most orders ship within 24 hours from one of our warehouses, and returns are risk-free for 90 days if a kit is not the right fit for your machine. See what RZR owners say about us.

Polaris RZR 4 Heater FAQs

Will a cab heater fit both the 2014-2023 XP 1000 and the newer Pro XP crew cab the same way?
No. These are two different chassis platforms with different mounting brackets, hose runs and dash cutouts. The XP 1000 crew cab (2014-2023) uses SuperATV's coolant-tap kit built for that dash. The Pro XP, Pro R, Turbo R and Turbo S crew cabs (2019-current) share a newer chassis and use Inferno's direct-fit kit instead.

Does installing a cab heater mean drilling into my dash?
Direct-fit kits like Inferno's Pro XP heater include a glovebox plate and drill template cut for that exact dash, so the holes land where the factory intended. A 12V plug-in heater needs no drilling since it runs off the existing power socket.

My RZR 4 has the glovebox subwoofer option. Does that change which heater I need?
Yes. SuperATV's standard cab heater is not compatible with machines that have a speaker mounted under the glovebox, and Inferno's kit ships with a glovebox plate designed to clear a sub-woofer. Check your glovebox setup before ordering.

Can each of the four seats get its own heat level?
A shared cab heater like the SuperATV or Inferno kit puts out one temperature for the whole cab. A seat heater kit like Moose's neoprene kit wires in separately with its own Hi/Low switch per seat, so the two systems work well stacked together.

Will a cab heater fog up my RZR 4 windshield?
The opposite. Inferno's and SuperATV's kits each route dedicated defrost vents to the windshield, so running the heater clears fog and frost rather than causing it. A 12V plug-in heater without a defrost vent will not do this.
