Evolution Powersports Maverick X3 Shift-Tek Helix Packages consist of technology originally developed for racing where adjustability and versatility play a key role to winning success. Our billet helix packages are for customers who are looking for the adjustability of the Shift-Tek system, but have their own primary clutch setup.
Our helix angles are all custom and the numbering system somewhat correlates to the stock values. Since clutching is a balance between the primary and secondary, there is no one 'magic' helix angle. EVP cannot make specific recommendations if your primary clutch setup has components from another company. However, generally if your rpm are too low, a shallower range helix and/or stiffer secondary spring will raise rpm. This will also provide more squeeze on the belt which is useful if you are experiencing belt slip. Conversely, if your rpm are too high, a steeper range helix and/or softer secondary spring will lower rpm. This will allow the secondary clutch open faster which can be beneficial under certain circumstances.
For those who already have our Billet Bearing Housing, other helixes are available separately in the drop down menu.
