STM Rage 3P/3RS Sportsman & Scrambler 850 / 1000

POLARIS RAGE BILLET PRIMARY

MUST BE USED WITH THE STM TUNER DRIVEN FOR 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.

A complete billet design that uses a screw-on style spider. Rigid reinforced design for higher horsepower applications. We have designed the Rage 3P to create more overdrive than the stock clutch system. To obtain the proper overdrive the STM Tuner Driven clutch must be used. These STM clutches will fit under the stock cover with no interference. The Rage clutches are capable of using most cam arms that are available on the market. We have incorporated a pin size option for every clutch we make by providing a pin conversion design in the movable sheave. Pin conversions are available in 1/4"and 5/16" diameter. We incorporate a fixed pin design that pivots the cam arm between two bushings and attaches the cam arm to the pin providing more durability to the cam arm pivot points.

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

The Rage is calibrated with a spring and set of our own adjustable SUPERTIP 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.

Once you add your unit info we will setup the clutch for your riding needs
