Introducing the new STM 3-RA Polaris Sportsman / Scrambler 850 - 1000 Primary Clutch. This is an upgrade from the Rage 3P primary. Now equipped with steel slider plates, all new composites, new cam arm design for greater longevity and performance capabilities.
The new design also allows for far greater air flow in/around the clutches as well as forcing more air out from the clutch housing. This keeps your clutches and belt running cooler by an average of 20-30 degrees in track racing tests when designing the new clutch.
MUST BE USED WITH THE STM TUNER DRIVEN FOR BEST RESULTS! A NEW BELT IS ALSO HIGHLY RECOMMENDED IF YOU BELT IS WORN TO YOUR ORIGINAL CLUTCHES!

This clutch offers extremely smooth low engagement with improved torque. The clutch also offers cooler belt operating temperatures, as tested.
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 outperforms the existing primary. Using our adjustable SUPERTIP CAM ARMS with the 3-RA is the perfect recipe for your stock or modified Polaris Scrambler or Sportsman.
The 3-RA comes calibrated with a spring and a set of our own adjustable SUPERTIP CAM ARMS.
