The CryoHeat Polaris RZR 4WD ProMod Transmission is lighter and provides faster acceleration all the way to top speed. Our customers world wide are pulling hole shots with over 5 car lengths from when the green flag drops to 100 yards and dessert racers are seeing 8-10 mph more top speed depending on clutch set up. This is the best way for faster UTV by putting less load and duty on the clutch belt. We remove 10 lbs of rotating mass with back-cut gears, three gun-drilled shafts, precision-drilled holes in the gears including the final drive gear and a beautifully machined parking brake. All CryoHeat ProMod transmissions include CryoHeat/Micropolishing processing.

The CryoHeat Process makes the steel parts in the UTV transmission 28-30% stronger, depending on the type of steel. Aluminum is 18-21% stronger. Service life is increased 250% or better, saving you repair time and money. The UTV parts hold better dimensional stability and greater heat dissipation allowing them to run cooler during operation. We have seen over a 50°F temperature drop in the transmission with long distance racing.

The Micropolishing Process allows the metal to move with almost zero resistance. This dramatically reduces the friction that causes heat and drag that slows down the parts reducing the power from the engine. Faster speeds and power gains are achieved with this process.

Best In The Game

I’ve had this transmission in my desert car for 2 seasons and finally had it serviced and it looked brand new. Thank you Cryoheat for building awesome transmission. I also run cryo heat brakes, diff, axles, motor, etc depending on the class I race. Best in the game 👊🏻👊🏻

Pro mod rocks!

I have a 2021 xp4T. I wanted to upgrade the transmission bearings to get ahead of a catastrophic failure. The owner of cryoheat Josh talked me into doing a pro mod 2 upgrade since all the effort would be invested in splitting the case anyway. SO GLAD I LISTENED!! I run dunes and desert in my car with other xp’s. My car is noticeably faster from low end all the way through to top end. When running paddles my car spools up right away, the power is available like RIGHT NOW! All this with peace of mind knowing I’ve got the strongest transmission available for my RZR.
