Product Description
A Brock’s Performance Clutch Mod is the key to launching the ZX-14R smoothly and consistently from a dead stop. By disabling the factory slipper clutch, this upgrade eliminates the harsh grab-and-jerk motion of the stock setup, giving riders the ability to perform smooth, controlled launches every time.
Precision-Tuned for Drag-Style Launches
This complete kit includes heavy-duty clutch springs and spacers that increase clutch pressure without creating chatter or reducing top-end speed. With shim-adjustable spring tops and a full Clutch Shim Assortment Kit, you can fine-tune spring pressure to perfectly match your riding style or racing application.
Our springs are manufactured from valve-spring quality material, shot-peened and stress-relieved to withstand the extreme heat and stress of high-power sportbike launches. The result is unmatched durability, smoother operation, longer clutch life, and lower ETs.
