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 and quiet operation. 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 the RS-1 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 especially on higher HP machines. The Rage 3WCP clutch works well with stock and aftermarket tunes that utilize the stock turbo and pump gas, for race gas tunes or bigger turbos we recommend the Rage 4WCP primary clutch 3001122.
Included with the clutch is a fastener kit to calibrate the cam arms, and a compression tool to help change the weights or spring in the clutch without removing it from the engine.
The Rage 3WCP utilizes the STM PATV style springs available on our website. 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. This clutch uses the OEM belt specified for your machine. Aftermarket belts can also be used however most of the time an aftermarket belt will require a slightly different calibration for maximum performance/belt life. This primary can be used with the OEM secondary or the billet STM Tuner secondary clutch.
This primary will work with the stock secondary.
