POLARIS RAGE DUAL STAGE BILLET PRIMARY
With the XP900 we experienced 10MPH GAIN OVER THE STOCK CLUTCHES.
New improved two-way bearing design. The main shaft bearing is now smaller with a 45mm 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 3 to create more over drive than the stock clutch system. To obtain the proper over drive the tuner driven clutch # 299PATVD must be used. 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 moveable 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.
WE HAVE A TESTED SET UP FOR YOUR TURBO CHARGED RAZOR THAT FLAT OUT PULLS!
The NEW TRIPLE roller option with a 1.25 diameter roller creates a very consistent smooth up shift and back shift with improved roller wear. This latest design creates a huge improvement in engine braking compared to our dual roller Tuner. All billet construction capable of using compression springs with different spring rate options.
