STM Powersports 2010-2019 Can-Am Commander Rage 8 Primary Clutch

New improved two-way bearing design. The main shaft bearing is now smaller with a 47mm outside diameter allowing a lower initial takeoff 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 3 is the perfect recipe for your stock or modified Outlander. To take full advantage of an optimal setup, we suggest using the Tuner driven 302BATVD along with the Rage 3.  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 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. All parts are replaceable and stocked.

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

We offer the Rage 3 calibrated with a spring and set of our own adjustable SUPERTIP CAM ARMS.

Comes with a belt removal tool and bolt for installation.

Each clutch is assembled and setup to run the BRP OEM belt. 

We have tested setups for your particular application. You bolt it on and GO!

DUE TO OFFSET DIFFERENCES THE RAGE PRIMARY HAS TO BE USED WITH THE 302BATVD SHORT POST TUNER DRIVEN AND THE LONG POST WITH THE STOCK PRIMARY.
