NCY Ball-Bearing Secondary Spring Seat | GY6 & QMK 125-170cc stators Reduced Friction: The polished internalThe NCY ball bearing secondary spring seat eliminates CVT spring twist and binding on GY6 125 150 170cc engines. In a stock setup, the torque spring must twist as it compresses, creating internal friction that slows downshifts and reduces belt life. This NCY upgrade uses an integrated ball bearing assembly that allows the spring to rotate freely during compression and decompression, resulting in faster, more consistent CVT response.
