 Product Description

 A simple bolt-on that utilizes the old style OEM Arctic Cat helixes and springs providing a much wider variety of tuning options. The tuner is made from T6061 aluminum and heat treated steel hub and towers. The movable sheave has reinforced towers for the higher HP applications when needed. It also has a belt deflection adjuster (no shims needed) and non wearing rollers.

 
The TUNER wakes up machine creating a better up shift and back shift.  This bolt-on will help with eliminating belt heat that plagues the stock driven. 
 
The Tuner comes with no spring or helix . We offer spring and helix combos for an additional fee. This STM tuner runs with the OEM stock belt.

All parts and bushings can be replaced and serviced.
