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
