POLARIS RAGE SINGLE-STAGE BILLET PRIMARY

 

MUST BE USED WITH THE TUNER 299PATVD DRIVEN FOR BEST RESULTS! 

 

The new improved design is offered in a one-way or two-way bearing. 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. The oneway option improves engine braking when descending downhills and braking.  

 A complete billet design that uses a screw-on style spider. Rigid reinforced design for higher horsepower applications. We have designed the Rage III to create more overdrive than the stock clutch system. To obtain the proper overdrive the Tuner Driven clutch # 299PATVD must be used. These STM clutches will fit under the stock cover with no interference. The Rage III 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. Each clutch assembly comes with assembly - disassembly tools.

We offer the Rage calibrated with a spring and set of our own adjustable SUPER TIP CAM ARMS for an additional $165.00. Each clutch is assembled and set up to run the Polaris OEM belt 32111130. Uses the stock primary bolt.
 

***WE HAVE A TESTED SET UP FOR YOUR TURBOCHARGED RAZOR THAT FLAT OUT PULLS!***
 

Item number 92-10 primary clutch holding tool is required when removing or installing the spider. Works on all STM primary clutches. Sold separately.
