We are proud to offer our new Pro-Shift Torsion Overdrive Clutch Kits for the Ski Doo G4 Summit and Backcountry models for low elevation! These kits really work amazing!!
We have clutch kits like no other!! Utilizing our overdrive helix and torsion spring design, and our Pro-Mag weights.
This kit has killer throttle response, awesome acceleration, and great top speed gains!
Our custom helix design utilizing our Torsion spring allows the clutches to shift out further and more efficiently. This helps keep the clutches running cooler for longer belt life and the best part is you gain more top speed. Allowing the secondary clutch to open further for more overdrive.
Our Pro-Mag weights really help grab the belt much better creating less belt heat and better efficiency. The stock weights simply have too light of tip weight compared to our Pro-Mag weights. And though the Pro-Mag weights are adjustable up to 21 grams each using magnets, we have a preset setting for you. Our Pro-Mag weights are formed with a oil impregnated metal to lubricate the surface of the weights and roller for better durability. The kits work great on stock motors, or even with aftermarket single pipes and reed valves. We even have a setup for big bore kits.
These kits come complete with a new torsion style custom helix, torsion driven spring, Pro-Mag weights and a new drive clutch spring as well.
