DESCRIPTION

Speed Shop Inc Polaris Snowmobile Mountain Series Proshift Clutch Kit

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. 

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. 

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.  There are even two angle options machined into the helix.  One is for stock machines, and the other is for machines modded for more power.

These clutch kits come with the 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.

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.
