STM Rage 3WCP Primary Clutch
The STM Rage 3WCP is a completely redesigned primary clutch built for durability and performance. It features a new, wider, and more durable spider with composite roller bushings for an extended lifespan.
Key Features:
- Durable Design: The new captured pin and set screw design provides maximum durability, while composite cam arm bushings withstand harsh conditions.
- Cooler Operation: A new finned fixed sheave increases airflow to keep the clutch running cooler.
-
Versatile Cam Arms: The Rage 3WCP offers two styles of adjustable cam arms to dial in performance:
- AFP Series: Ideal for naturally aspirated and lower-power turbo applications.
- HB Series: The "humpback" design provides excellent belt grip at low speeds and strong mid-to-top end performance.
-
Wide Compatibility:
- Works with stock or aftermarket tunes on stock turbo setups.
- Compatible with the OEM secondary or a billet STM Tuner secondary clutch.
- Fits under the stock clutch housing without modification.
- Works best with OEM belts, but can be calibrated for aftermarket replacement belts.
The clutch comes with a new retaining bolt, bolt insert, lock washer, and a fastener kit for adjusting the cam arms. It is shipped fully assembled with a baseline weight setup based on your machine's specifications.
Please Note: It is the customer's responsibility to properly calibrate the clutch for their machine using the provided instructions. For higher-power setups (350+ HP) or larger turbos, we recommend the Rage 4WCP primary clutch.
