Rage 3 Wide Captured Pin Primary Clutch
Completely redesigned STM Rage 3WCP Primary clutch features a wider, thicker, more durable spider with our new composite spider roller bushings for long life. The new design utilizes a captured pin with set screws for maximum durability and ease of use. Along with the new captured pin design we have all new composite cam arm bushings for long life in harsh environments. We have also added a finned fixed sheave for added air flow and cooler operation.
The Rage 3WCP primary has two different styles of adjustable cam arms available. The AFP series of weights are used for naturally aspirated and lower power turbo applications. The HB series weights feature a "humpback" design and offer good belt grip on the bottom end and awesome mid-to-top end performance.
The Rage 3WCP clutch works well with stock and aftermarket tunes that utilize the stock turbo, for bigger turbos or Higher power setups (350+ HP) we recommend the Rage 4WCP
Includes a new retaining bolt, bolt insert, and lock washer.
This primary can be used with the OEM secondary or the billet STM Tuner secondary clutch
Fits under stock clutch housing without modification
Included with the clutch is a fastener kit to adjust the cam arms
The clutch will be shipped fully assembled with a BASELINE weight setup installed based on the specs of the machine the customer provides. It is the customers responsibility to ensure that the clutch is calibrated properly for their machine per the instructions provided.
The optional primary compression tool (PN 1001022) is available to change the weights or spring while the clutch is still installed in the machine.
OEM belts work the best in our testing, however any aftermarket replacement belt will work it just may require a different clutch calibration/ setup.
The stock clutch puller will be required to remove the OEM clutch. Either the PCP-8 or PCP-24 will remove the STM primary.
KEEP IN MIND WE CAN ONLY GET YOU CLOSE WITH WEIGHT SET UP. Everyone's riding style is different so it’s up to the customer to do the fine tuning! Please call or text us with your machine details.
