Kawasaki Teryx H2 VORTEX Tuner Secondary Clutch Assembly

Complete your Kawasaki Teryx H2 driveline upgrade with the STM VORTEX Tuner Secondary Clutch Assembly. Designed entirely from the ground up specifically for the new H2 platform, this premium all-billet secondary clutch eliminates the sluggish backshifting and power loss of the stock factory setup.

When paired with the STM Rage 3 Primary Clutch, testing has proven this secondary delivers drastically faster acceleration, sharper throttle response, and the durability needed to handle oversized tires and heavy off-road abuse.

Billet Strength & Seamless Fitment

Forget cheap cast components. The VORTEX Tuner Secondary is CNC-machined from high-grade billet aluminum and composites, offering maximum strength and heat dissipation to prevent belt slip under extreme loads. Best of all, it features a true bolt-on design that fits perfectly under your stock clutch housing with zero modifications required.

Key Features & Performance Benefits

• H2 Platform Specific: A completely new architecture engineered exclusively for the 2026+ Kawasaki Teryx H2 platform.
• Lightning-Fast Backshifting: Keeps your RPMs exactly where they need to be when you let off and get back on the throttle, resulting in instant power delivery.
• Proven Acceleration: Dyno and trail-tested to provide significantly faster acceleration compared to the OEM secondary clutch.
• All-Billet Construction: Built from premium aerospace-grade materials for ultimate durability and cooling.
• Direct OEM Replacement: Fits under the stock factory clutch cover without any rubbing or cutting. The clutch housing comes on and off easier with our clutches then with the stock clutches even. 

Dial In Your Setup

No two rigs are built the same. The VORTEX Tuner Secondary lets you customize your shift curve based on your tire size and riding style.

• Required Spring: Comes paired with STM's Pink secondary spring for optimal tension and belt grip.

• Custom Helix Options:

• K1 Helix: Designed for heavy loads, deep mud, rock crawling, and running massive 36"+ tires.
• K2 Helix: Perfect for trail riding, dunes, and stock-to-mild tune-ups running up to 35" tires.

Don't let a weak factory secondary clutch rob your H2 of its true potential. Upgrade to the STM VORTEX Tuner Secondary today for unmatched response, cooler belt temps, and race-winning acceleration.

• Complete Mechanical Redesign: Unlike a basic weight/spring kit, STM builds complete primary and secondary clutches from the ground up to completely delete factory CVT failure points (like flexing towers or sticking weights).
  
• Under-Cover Fitment: A major engineering win for the STM system is that both the Rage 3 Primary and this VORTEX Secondary fit seamlessly under the stock factory clutch cover without needing to cut or modify the plastics.
  
• Infinite Tunability: Their spread-pin architecture allows owners to precisely dial in base weights (ranging from 50g to 72g) and custom helix configurations depending on whether you are running large mud tires, standard trail setups, or racing dunes.
