Polaris RZR Trail S 900 Cab Heater

Winter doesn't have to mean parking your RZR. A cab heater lets you ride comfortably year-round, even when it's freezing outside. This heater pulls warmth directly from your engine coolant—the same way your truck or car does—and pipes it into the cab where you need it. You get adjustable heat and fan speed, so you can dial in exactly how warm you want it. Your windshield stays clear too, with dedicated defrost vents that fight snow, ice, and fog buildup.

The kit comes completely assembled and ready to bolt in. You'll get radiator hoses rated to handle temperatures from -40°F all the way to 285°F, so cold weather and hot engine temps won't stress the system. All the tubing, vents, and mounting hardware are included. A hole saw kit and hose pliers come in the box to make installation straightforward. Everything stays tucked under your dash and out of sight.

You have options depending on how fast you want warmth. A quick-start flow valve cuts warm-up time by about half—it pushes all the engine coolant straight to your heater core when the engine is cold, then automatically switches to feed the radiator once things heat up. Or go with the idle flow pump if you want heat blowing hot in just 30 seconds, even when you're barely moving or sitting still.

You'll need to drill through the plastic dash and firewall to mount this heater. Don't worry—SuperATV includes the drill bits you need, plus pliers and all fasteners. Most people have it running in an afternoon.
