NCY Ball-Bearing Secondary Spring Seat (GY6)

Smooth Shifting: NCY Ball-Bearing Secondary Spring Seat Eliminate CVT binding and "spring twist" with the NCY Secondary Spring Seat . In a stock GY6 setup, the torque spring must twist as it compresses, creating internal friction that slows down your transmission's response. This NCY upgrade features an integrated ball-bearing assembly that allows the spring to rotate freely, ensuring lightning-fast downshifts and much smoother overall belt operation. Technical Performance Features Anti-Binding Technology: The bearing seat allows the secondary spring to decompress without torsional resistance, providing consistent "pop" and more responsive acceleration. Reduced Belt Heat: By smoothing out the opening and closing of the rear pulley, this seat helps reduce parasitic drag and excessive heat buildup in the CVT belt. Hardened Steel Construction: Engineered to withstand the high-RPM environment of performance GY6 builds, ensuring the bearings stay seated even under extreme spring tension. Improved Downshifting: Noticeably improves the scooter's ability to "find the right gear" when coming out of corners or hitting inclines.

Because the spring is harder to compress, the binding effect is much more pronounced.
