Use our STM tuner driven for the best results!

New improved two-way bearing design. The main shaft bearing is now smaller with a 47mm outside diameter allowing a lower initial take-off ratio than our past design. Allows tighter belt deflection, transmission shifting, and belt chirp.

The primary is designed to use Polaris ATV springs providing a wide variety of spring rates to choose from.

The Rage 3 is calibrated with a spring and set of our own adjustable SUPER TIP CAM ARMS. Each clutch is assembled and set up to run the Polaris OEM belt (stock belt for each machine). Uses the stock primary bolt.
