Maximize Your CVT Performance: NCY Adjustable Torque Driver
Eliminate mid-range "flat spots" and take full control of your powerband with the NCY Secondary Sliding Sheave. Engineered as a high-performance alternative to the linear factory pulley, this "Torque Driver" features dual-machined ramp angles. This allows you to choose between an aggressive curve for instant "off-the-line" snap or a progressive curve for smoother, high-velocity cruising.
