Variator guides 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 or slider weights.

- Set of 3
NOTE: 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.
