MOUNTAIN SERIES PRO SHIFT KITS are designed for long track models in deep snow. They are tuned for very quick throttle response in deep snow when boondocking and climbing, so that you have instant power all of the time.
We gained low end, mid range and top end pull with these awesome kits.
Our clutch kit come with our PRO Mag weights, new primary spring, secondary driven clutch spring, and our custom machined helix that actually has two angle options machined into it. The weights have 21 grams of adjustment per arm using magnets that weight just 1.3 grams each. Though every kit comes with a specific recommended setup.
Our kits work on stock machines or even if you have a pipe, head or muffler installed. Simply add a little more weight for the extra power.
