NCY Variator Slide Pieces Set of 3 - 139QMB 50cc 4T Scooters

Variator slides are the guides between the variator pulley and the back plate. These are commonly overlooked during service but wear gradually and can cause excess noise and a loss of CVT performance and acceleration. Inspect and replace whenever servicing roller or slider weights.
