Our new cam arms fits all 2016 and newer Proclimb and XF models using Team drive clutches. Turbo Mag (TM) Cam Arms are more aggressive than the factory cam arm profile and shift characteristics.TM Cam Arms are designed to be used in aggressive trail riding and turbo charged applications. TM Cam Arms are ideal for drag racing and have a very aggressive up-shift. TM Cam Arms act 5 grams heavier than the factory weight and must be ordered 5 grams lighter (i.e. 70 gram TM weight acts like a factory 75 gram weight and runs at the same RPM as a 75 gram factory cam arm weight). You can now adjust the weight of these cam arms in seconds by simply adding or subtracting set screws. It is that easy! This new generation of cam arm is manufactured specifically for the new Arctic Cat/Team drive clutch and has a double drilled and taped cavity for more adjustment. The adjustment can be made without the removal of the cam arms or drive belt. You can now purchase one set of cam arms and have the ability to add up to 10+ grams of weight. Each kit comes with an assortment of set screws. Adjustments are made with the included Allen wrench.
