Our Billet Head for the Arctic Cat 858 is an easy way to bolt on some easy power. We have changed the combustion chamber design to produce a quicker revving motor, make more horsepower and torque and also provide better characteristics to prevent detonation on an otherwise stock machine. You can expect a 6-8 horsepower gain with huge torque gains with these heads at higher elevations and 2-4 at lower elevations. We have two options to chose from - high elevations should be used at 6500'+ and low elevation if you are running 0-6500'

Small design for additional weight loss and more room for install

Direct Bolt on, easy install

These heads work amazingly well and one of the best features is it takes almost a full pound of weight from the factory head!

No Fuel Controller needed on a stock motor!!

Premium fuel, 91 required

The Pro-Cool Billet Head Kits come with one beautiful looking head cover and 2 domes. Extra domes are available for different elevations and applications.

MAKE SURE TO PICK THE CORRECT ELEVATION IN THE DROP DOWN MENU WHEN ORDERING
