Yes they do.
There are a number of things to point out.
1. External drive belt or belts. If your charger pulley has two belts that drive it, then they are cogged vee belts (known as v belts) and are stock from the factory. If this is like a cam belt, then it has toothed pullies and these are either alloy (psd) or steel (from germany). Club g40 supplies toothed belts to fit the psd toothies at £14 each.
2. internal belt. There is a small timing belt on the charger (visible when you take it off the car) club g40 supplies these at £6 each and should ideally be changed annually!
jabba do still do g40 stuff.
