Our new cam arms fit all 2016 and newer Proclimb and XF Models. Improved Trail (IT) Cam Arms replicate the factory cam arm profile and shift characteristics. IT Cam Arms are designed to be used in mountain and high elevation applications. IT Cam Arms up-shift and back-shift identical to factory cam arms, except they can be adjusted for weight. IT Cam Arms match the factory weight gram for gram. 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 accessibility of this 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 8 + grams of weight. Each kit comes with an assortment of set screws. Adjustments are made with the included Allen wrench.
