Clutch Spring Features & Benefits:

Built for Extreme Durability- Our clutch springs are treated with double shot peening, a proven process that relieves internal stress and enhances fatigue strength. This significantly extends the lifespan of each spring—even in the most demanding riding conditions.

Precision Pre-Stressed & Tested- Every spring is pre-stressed and thoroughly tested to ensure top-tier performance and consistency. This reduces the risk of early failure and ensures that your machine responds with precision every time.

Enhanced Protection with Powder Coating- Unlike traditional paint, our powder-coated finish delivers superior durability. It resists chipping, corrosion, and wear, keeping your components looking and performing like new longer.

Backed by a Lifetime Warranty – We believe in the quality of our craftsmanship. That’s why every clutch spring comes with a lifetime warranty—giving you confidence in every throttle pull.

Clutch Weight Features and Benefits?

Fully Treated & Precision Balanced- Every weight is fully treated and precisely balanced, ensuring consistent performance, optimal clutch engagement, and smoother acceleration. This meticulous treatment delivers superior reliability at any RPM.

Heat Treated & Post Baked for Strength- Our weights undergo a rigorous heat treatment and post-baking process, enhancing their durability and reducing wear. This ensures they maintain performance even under extreme stress and high temperatures.

Yellow Zinc Plated – Corrosion Resistant- A yellow zinc plating shields each weight from the harshest environments, resisting rust and corrosion for long-lasting performance.

Fully Adjustable for Customized Setup- Tunable to your machine and riding style, the completely adjustable design gives you the flexibility to dial in the exact shift curve and performance characteristics you need—whether racing, trail, or mountain riding.

Take full control of your Polaris 900R’s performance — with a clutch kit designed for riders who demand precision and power.
