STM Polaris General 1000 Rage 3P Primary Drive Clutch

To take full advantage of an optimal set up we suggest using the STM driven along with the Rage3P.  

This clutch offers extremely smooth low engagement with improved torque. Big tires or low speed riding is no longer a problem with the STM Rage3P.

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 and smoother transmission shifting.

An affordable replacement for the stock primary clutch. Complete billet design that out performs the existing primary. Using our adjustable SUPERTIP CAM ARMS with the Rage 3P is the perfect recipe for your stock or modified Machine. These STM clutches will fit under the stock cover with no interference. The Rage 3 is capable of using most cam arms that are available on the market.  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. All parts are replaceable and stocked.

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

The Rage 3 comes calibrated with a spring and set of our own adjustable SUPERTIP CAM ARMS.

Each clutch is assembled and set up to run the OEM belt.

This primary will work with the stock secondary.
