Clutching is the key factor to optimize the performance of your machine. Whether you have a stock or modified machine there is a lot of performance to be gained with our ProShift Clutch Kits.
BACK COUNTRY PRO SHIFT KITS are designed for longer track models to be run at low altitudes in deep snow. They are tuned for very quick throttle response in deep snow for off trail riding, so that you have instant power all of the time.
We gained low end, mid range and top end pull with these awesome kits. There are even two angle options machined into the helix. On is better for harder snow, and one is better for deeper snow.
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 16 grams of adjustment per arm using magnets that weight just 1.3 grams each.
