*NEW 2025* - Kit includes a custom Thermostat bypass housing that sits behind the OEM thermostat providing faster and more consistent heat.
A heater for the Yamaha Wolverine RMAX4 1000 Compact, 2020–2025
This Ice Crusher dual-fan heater kit is built specifically for the Yamaha Wolverine RMAX4 1000 Compact — not a universal heater adapted to fit. The dual-fan heater core moves twice the air of our single-fan kits: 18,000 BTU and 320 CFM through 6 adjustable vents — two defrost vents, two hand vents and two rear vents for the back-seat passengers. The heater unit mounts under the driver seat. Because it runs on engine coolant, it makes real heat without draining your battery; the dual fans draw just 2–3 amps.
Everything is in the box: heater, vents, hose, fittings, hardware and the specialty tools the install needs, with picture-rich, step-by-step instructions written for the average do-it-yourselfer. Plan on four to eight hours depending on experience.
Order during business hours and it ships the same day from Minnesota. If you get stuck mid-install, call 888-964-0135 — tech support is unlimited and free for as long as you own the heater, and the warranty is simple: tell us the problem and we fix it.
FITMENT NOTE: DOES NOT WORK WITH RMAX4-1000 (only 1000-Compact)
