NCY sliders for Honda PCX. These CVT sliders are constructed of a low-friction polymer to resist premature wear and ensure proper operating tolerances. Sold in sets of three. Variator guides (or ‘sliders’) are the spacers between your variator pulley and the back plate. Regular service of these guides is often overlooked, and may cause excess noise and a loss of performance and acceleration. Variator guides are a fairly inexpensive component and it makes sense to check them when replacing your roller weights. We also recommend checking the wear on your clutch while you’re in there, a faulty clutch can be devastating to your pocket and your other transmission components.
