A heater for the Massimo T-Boss 550 / 560, 2018–2025
This is the Ice Crusher cab heater kit for the Massimo T-Boss 550 and T-Boss 560. It taps into the machine’s coolant, mounts on the firewall, and puts 16,000 BTU through four vents (two in the cab, two for defrost).
We design and build this kit in Minnesota. It is not a universal box with a T-Boss label. Hardware, hoses, fittings, and picture instructions are in the box.
Fits
2018-2025 Massimo T-Boss 550 and T-Boss 560, including:
- T-Boss 550, 550F, 550X, 550X Golf
- T-Boss 560, 560X Golf
- T-Boss 550L and 560L (these already have factory heat; most L owners do not need this kit)
If you are not sure of the year or trim, call 888-964-0135.
Defrost Note: The OEM Tip-up windshield has a sizeable bend in the lower portion that will impede defrost flow. The Defrost version of this kit is best suited for aftermarket windshields that do not have this lip.
Premium Components:
- Heavy Duty single-piece Brass 'Y' Fittings, no chance of leaking from poor welding or threaded joints.
- 316 Stainless Steel Hose Clamps will never corode
- Metal ribbed Duct Hoses (vs plastic ribs) are virtually impossible to crush if kicked or stepped on.
- Plug and Play T-Harness for fast install
You'll never be stranded during installation because our Minnesota-based technical support team is ready to help! Put the fun back in your outdoor activities with an Ice Crusher UTV Heater.

- Vents: 4 (2 Center, 2 Defrost)

Hose Clamp Off Pliers Option:
A pair of 10-inch clamp-off pliers that seal hoses up to 2 inches, so coolant stays in and less air gets into the system when you tie in. Bleeding the air out afterward is much easier, and they work on radiator hoses too.

MaxStat - Inline Coolant Bypass Thermostat Option:
Adds about 10–15° of cab heat. The MaxStat is an inline bypass thermostat (180°F, or 192°F if you ask before it ships) that keeps hot coolant flowing to the heater core when the engine thermostat would otherwise close, so the heat stays steady instead of cycling.
