STM Rage 3WCP Wide Captured Pin Primary Clutch

Upgrade your Can-Am CVT with the STM Rage 3WCP Primary Clutch, a fully adjustable billet primary clutch designed for improved durability, performance, and tuning flexibility across a wide range of Can-Am UTV applications.

The Rage 3WCP features STM's Wide Captured Pin design, combining a wider, thicker spider with captured cam-arm pins secured by set screws. Composite spider roller bushings and composite cam-arm bushings are designed for long service life in demanding off-road environments, while the finned fixed sheave increases airflow through the clutch to help improve cooling.

Whether you're running a naturally aspirated machine, stock-turbo Maverick X3, tuned trail machine, or modified Can-Am, the Rage 3WCP gives you the adjustability needed to dial in clutch performance around your horsepower, tire size, elevation, vehicle setup, and riding style.

Built for Performance & Adjustability

Unlike a fixed factory clutch setup, the STM Rage 3WCP uses adjustable cam arms and interchangeable primary springs, allowing the clutch calibration to be tailored around the way your machine is actually being used.

Benefits include:

  • Fully adjustable clutch calibration
  • Excellent belt grip and acceleration
  • Multiple cam-arm styles and base weights
  • Wide range of primary spring options
  • Strong tuning flexibility for modified machines
  • Finned fixed sheave for increased airflow
  • Durable Wide Captured Pin design
  • Composite spider roller and cam-arm bushings
  • Works with OEM or STM secondary clutches
  • Fits under the factory Can-Am clutch housing without modification
  • Fully assembled with a baseline calibration

Baseline Calibration Included + Treal Performance Setup Support

One of the biggest advantages of ordering your STM Rage 3WCP through Treal Performance is that you do not have to figure out the spring and cam-arm combination completely on your own.

STM offers a wide range of primary springs, cam-arm styles, and weight combinations because every machine is different. Horsepower, turbo setup, tire size, vehicle weight, elevation, terrain, and riding style can all change what the clutch needs.

That's where we come in.

After placing your order, send us your machine information and we'll help point you in the right direction for an appropriate baseline setup. Your clutch will arrive fully assembled with a starting calibration based on the information provided, giving you a much better place to start than simply guessing at springs and weights.

After Placing Your Order

Please email Sales@TrealPerformance.com with your order number and the following information:

  • Year
  • Make and exact model
  • Engine modifications
  • Stock or aftermarket turbo
  • Turbo model, if applicable
  • Tune and/or estimated horsepower
  • Tire size
  • Exact tire being used
  • Elevation where you normally ride
  • Riding style
  • Typical terrain and riding conditions
  • Any desired clutch engagement characteristics

If you already know the exact STM spring, cam-arm style, or weight setup you want, include that information in your email.

If you don't, that's completely fine. Send us your build information and we'll help guide you toward the right starting setup.

Why We Ask for This Information

There isn't one clutch calibration that's perfect for every Can-Am.

A stock Defender on 30-inch tires needs something very different from a tuned Maverick X3 on 35s, and a dune setup may require something different from a trail, mud, or utility machine.

By looking at your complete combination, we can help narrow down the spring and cam-arm setup before the clutch ever gets to you.

The goal is to get you as close as possible from the start while still giving you the adjustability to fine-tune the clutch for your exact machine.

Adjustable Cam Arms & Weight Options

The STM Rage 3WCP uses adjustable cam arms that allow the clutch to be calibrated around your machine's horsepower, turbo setup, tire size, elevation, vehicle weight, and riding style.

AFP Series

STM's AFP adjustable weights are intended primarily for:

  • Naturally aspirated applications
  • Lower-power turbo applications

HB Series

The HB "Humpback" Series is designed to provide strong belt grip on the bottom end while maintaining excellent mid-range and top-end performance.

STM also offers X-Style and high-engagement HBRN cam-arm options for specific combinations.

Available Base Weight / Cam Arm Options

  • 50 Gram Base .570" Wide HB Series - Part #1001585
  • 60 Gram Base .570" Wide HB Series - Part #1001584
  • 50 Gram Base AFP Series - Part #2001151

These are the base cam-arm weights. Additional weight can be added during final clutch calibration using the supplied cam-arm fastener kit.

Available Primary Spring Options

The Rage 3WCP is available with a large selection of STM primary springs, allowing engagement and operating characteristics to be matched to different machines and power levels.

You do not need to know which spring to choose before ordering. If you're unsure, send us your machine information and we'll help guide you toward an appropriate baseline setup.

Wide Captured Pin Design

The Rage 3WCP uses STM's Wide Captured Pin design, featuring captured cam-arm pins secured with set screws.

The clutch also uses a wider and thicker spider along with composite spider roller bushings and composite cam-arm bushings for durability in demanding UTV applications.

This design provides a strong, serviceable platform while maintaining the adjustability needed for performance clutch tuning.

Finned Fixed Sheave

The Rage 3WCP features a finned fixed sheave designed to increase airflow through the clutch.

Managing heat is especially important in UTV CVT systems, particularly on modified machines, heavy vehicles, larger tires, dunes, mud applications, and other conditions that place increased load on the belt and clutch system.

Great Choice for Stock-Turbo & Tuned X3 Builds

The Rage 3WCP is an excellent choice for naturally aspirated applications, stock-turbo Maverick X3s, and many stock-turbo machines running aftermarket tuning.

For larger turbochargers or higher-power combinations around 350+ HP, STM recommends stepping up to the Rage 4WCP Primary Clutch.

This makes the Rage 3WCP an excellent option for customers who want a high-quality, highly adjustable primary clutch without moving into a clutch designed around significantly higher horsepower combinations.

Works With OEM or STM Secondary Clutch

The Rage 3WCP can be used with your factory Can-Am secondary clutch or paired with an STM Tuner Secondary for an even more adjustable CVT package.

This allows you to upgrade the primary clutch without requiring an aftermarket secondary at the same time.

Fits Under the Factory Clutch Cover

The STM Rage 3WCP is designed to fit beneath the factory Can-Am clutch housing without modification.

Installation uses the factory Can-Am clutch bolt along with the supplied STM clutch insert and lock washer.

For clutch removal, you can use either the OEM Can-Am clutch puller or STM clutch puller Part #1001190.

Belt Compatibility

STM reports the best results in its testing with OEM Can-Am drive belts.

Aftermarket replacement belts can also be used, but differences in belt dimensions, construction, and compound may require additional clutch calibration to achieve the best performance and belt life.

Optional STM Primary Compression Tool

For customers who plan to fine-tune their clutch setup, the optional STM Primary Compression Tool, Part #1001043, allows the primary spring or cam-arm weights to be changed while the clutch remains installed on the machine.

This is an excellent tool for racers, tuners, or customers who regularly change vehicle setups, riding locations, tire sizes, or power levels.

Fitment

Designed for compatible:

  • Can-Am Maverick X3
  • Can-Am Defender
  • Can-Am Maverick Trail
  • Can-Am Maverick Sport
  • Can-Am Commander

Please provide your exact year and model when ordering so the correct clutch configuration can be supplied.

Rage 3WCP vs. Rage 4WCP

Not sure which STM primary clutch is right for your build?

The Rage 3WCP is an excellent choice for naturally aspirated machines, lower-power turbo applications, stock-turbo Maverick X3s, and many stock-turbo vehicles running aftermarket tuning.

For larger turbochargers or higher-power combinations around 350+ HP, STM recommends moving to the Rage 4WCP.

If you're unsure which clutch is best for your combination, contact Treal Performance with your vehicle and build information and we'll help point you in the right direction.

Important Calibration Information

The supplied spring and cam-arm setup is intended to provide a baseline starting calibration.

Final clutch calibration remains the customer's responsibility. Horsepower, vehicle weight, tire size and construction, belt choice, elevation, terrain, modifications, and riding style can all affect clutch operation and may require additional spring or cam-arm weight adjustments.

The advantage of the STM Rage 3WCP is that you have the adjustability to make those changes as your machine, riding conditions, or performance goals evolve.
