Ultra Light Billet Clutch Mod Kit GSX-R1000 (05-06)

Description

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.

FEATURES

• 70% lighter than OEM back-torque limiter – allows faster engine acceleration
• Eliminates ‘bucking’ during dead-stop launches – smoother takeoffs, lower ETs
• Disables factory back-torque limiter (slipper clutch) for improved drag-style performance
• Billet 7075 aluminum, mil-spec hard coat – lightweight strength and durability
• Heavy-duty clutch springs – increased lever pressure for more consistent power transfer
• Smoother operation, longer clutch life, and improved drivability

Attention: While casual street riding is generally unaffected, some rear-wheel ‘chirp, hop, or chatter’ may be experienced depending on riding habits. All Brock’s Performance products are designed for Competition Use Only. Please review our for more details.
