These wheels help cool your hyfax to protect from excessive wear. Because they’re molded from UHMW material and don't have any rubber components, ice and snow will not stick to the wheels, thus eliminating vibrations caused from out of balance wheels.
Intake fan blade design on front bogies blows cold air into your snowmobile's skid or track to cool and lubricate hyfax and track components.
Exhaust fan blade design on rear bogies blows hot air and unwanted snow out of the snowmobile's skid, helping to prevent snow pack that can slow down moving parts.
Bogies are molded as a single piece of solid UHMW, one of the strongest poly materials on the market. And with no rubber components, they'll outlast any OEM idler wheel.
