Yamaha Wolverine Heaters
The Wolverine is the machine you take to work on Friday and into the woods on Saturday, and cold weather is where that double life gets tested. Load four people into an RMAX4 on a 25-degree morning and an open cab bleeds heat fast, while a coolant cab heater pulls 13,000 to 18,000 BTU off the engine to keep the whole crew warm and the windshield clear. There are passionate hunters on this team, and cold-season gear like this gets used in actual hunting season, not just described in catalog copy. Everything Yamaha Offroad carries a heater cut for every Wolverine, from a $47.49 seat pad to an 18,000 BTU dual-fan cab system.
Fit on a Wolverine heater starts with which one you own, because the cab heaters are built per variant. The X2 and X4 (2018-current), the RMAX2 and RMAX4 1000 (2021-current), and the original Wolverine (2016-2018) each take a model-specific coolant kit from Inferno, Ice Crusher or Moose. Seat heaters and 12V portable heaters skip all of that and fit any Wolverine. A coolant cab heater only earns its price in a cab you have closed in, so if your Wolverine still rides open, seal it up with a cab enclosure, or a windshield and doors at minimum, before you add heat.

BUYER'S GUIDE: How to Choose Yamaha Wolverine Heaters
Two questions decide a Wolverine heater: does it fit your exact model, and does it match how you use the machine. Coolant cab heaters give the most heat and the only real windshield defrost, but they are variant-specific and need a closed cab. Seat heaters warm the operator for under $100 and fit anything. Portable 12V heaters plug to the battery for quick spot heat. Start with the fitment map below, then work through build quality and price.
Which Cab Heater Fits Your Wolverine
| Your Wolverine | Model-specific cab heaters that fit | Cab-heater price |
|---|---|---|
| Wolverine X2 (2-seat, 2018-current) | Inferno X2, Ice Crusher Wolverine, UPI X2 | $427–$636 |
| Wolverine X4 (4-seat, 2018-current) | Inferno X4, Moose X4, UPI X4 | $427–$535 |
| Wolverine RMAX2 1000 (2021-current) | Inferno RMAX, Ice Crusher RMAX, MotoAlliance Firestorm | $399–$525 |
| Wolverine RMAX4 1000 (4-seat, 2021-current) | Inferno RMAX, Ice Crusher RMAX-4 Dual Fan, Moose | $427–$595 |
| Wolverine (original, 2016-2018) | Inferno 2016-2018 Wolverine, Ice Crusher Wolverine | $427–$636 |
Wolverine Heater Build Quality: Hoses, Blowers, and Wiring
Start with fitment, because a kit built for an X2 will not seat right in an RMAX4. From there the build shows up in the blower, the plumbing and the vents. A four-seat X4 or RMAX4 cab holds more air than a two-seat X2, which is why Ice Crusher runs a dual-fan core rated 320 CFM on its four-seat kit instead of asking one fan to do the job. Look for a real multi-speed blower, and Inferno uses SPAL, the same fans automotive heat relies on. Look for high-grade radiator hose too. MotoAlliance rates its hose to -40°C, and it ships with aluminum fittings and a built-in shutoff valve so you can stop coolant flow in summer. Count the vents while you are at it: the Ice Crusher Wolverine kit runs six adjustable vents, two of them aimed at rear passengers who otherwise freeze in a four-seat cab. On seat heaters, the tells are waterproof connectors and neoprene pads that survive mud and snow, not bare wire and open crimps.
What You'll Spend on a Wolverine Heater
The floor is operator warmth. A Tusk cold-weather seat heater is $47.49 on sale, the Moose seat heater kit is $94.95, and the RoadPro 12V ceramic heater is $99.99. Cheap, fast, and they work in an open cab.
Most owners running an enclosed Wolverine land in the $400 to $450 band, and the grid backs that up with seven listings sitting there. The MotoAlliance Firestorm underdash heater is $399.99 and carries a 3-year warranty, the Inferno RMAX, X2 and X4 cab heaters run $427 to $478, and UPI's Inferno-built kits are $449. That is real coolant heat with defrost for about the price of a good windshield.
The premium tier is where the four-seat and dual-fan kits live. The Moose Wolverine and X4 cab heaters are $534.95, the Ice Crusher Wolverine kits run $499.99 to $660.96, and the Ice Crusher RMAX-4 dual-fan tops the page at $569.99 to $594.98 with the most airflow of any kit here.
Warranty on most Wolverine heaters runs 3 to 6 months, but Everything Yamaha Offroad does offer extended 1- and 2-year warranties on all products if that is something you are interested in, added right at checkout. Brand terms are stronger on some: MotoAlliance backs the Firestorm for 3 years and Inferno covers its SPAL blower for 1 year. Every order is backed by a risk-free 90-day return, and many listings carry a downloadable install guide if you plan to do it yourself.

Yamaha Wolverine Heater FAQ
Which Wolverine cab heater fits my model?
Coolant cab heaters are variant-specific. Inferno, Ice Crusher and Moose each make kits cut for the X2, X4, RMAX2 and RMAX4, and Inferno still makes one for the 2016-2018 original. The Ice Crusher RMAX-4 dual-fan is the exception to watch: it fits only the four-seat 1000-Compact with tall sidewalls, not every RMAX4. Seat heaters and 12V portables fit any Wolverine. Text us your year and model and we will confirm the kit.
My RMAX has a factory cab. Do I still need a heater?
Yes. A factory or accessory cab seals the Wolverine in, but the enclosure itself adds no heat. A closed cab is exactly what makes a coolant heater worth installing, since it traps the warm air the heater makes. If your cab is buttoned up, add the coolant kit. If it is still open, a seat heater or a 12V portable is the better move.
What is the best heater for a Yamaha Wolverine?
It depends on your cab and seat count. The best-selling all-arounder is the Inferno cab heater with defrost at $427, cut per model. The value pick is the MotoAlliance Firestorm at $399.99 with a 3-year warranty. For a full four-seat cab, the Ice Crusher RMAX-4 dual-fan moves the most air at $569.99. The cheapest warmth is the Moose seat heater kit at $94.95.
Why does a four-seat Wolverine take longer to warm up?
A four-seat X4 or RMAX4 cab holds more air and has rear passengers to reach, so a single-fan kit can fall behind. A dual-fan core like the Ice Crusher RMAX-4 at 320 CFM, or an extender-vent kit that pushes air to the back seats, solves it. Coolant heaters also need the engine warm to make heat, so a bypass thermostat or MaxStat that keeps hot coolant moving at idle helps in deep cold.
Are Wolverine heaters hard to install?
Plan on an hour or two for a coolant cab heater. It taps the cooling system and mounts under the dash, under the hood or under the seat depending on the kit. Ice Crusher and Inferno include the CNC brackets, hose splicers, clamps, hole saws and wiring you need. Seat heaters and portables are close to plug-and-play. Many listings carry a downloadable install guide, and you can add an extended 1- or 2-year warranty at checkout.
