Take your performance to the next level with our Ultra-Light Billet Clutch Mod Kit—a proven upgrade that delivers quicker acceleration, smoother launches, and dramatically longer clutch life.
From the very first launch, you’ll notice increased MPH, improved drivability, and reduced wear thanks to our precision-engineered design.
This kit replaces the OEM two-piece back-torque limiter with a CNC-machined, one-piece billet aluminum unit, hard-anodized for maximum durability. The result? Nearly a 70% reduction in rotating mass in this critical area alone.
Also included is an ultra-light, hard-coated clutch plate that works seamlessly with our clutch springs and shim-adjustable spring tops to fine-tune spring pressure for optimal performance.
Unlike other setups, we shim the entire clutch pack—not the springs—to avoid issues with minimal thickness tolerances under the spring retaining screw heads. Plus, with this design, the factory clutch lifter pins, nuts, springs, and spring tops are no longer required. No core needed.
