Tech tip: Did you know that XRAY now offer complete ECS driveshaft sets for your X4? This makes life easier, since you don't need to order all the parts individually anymore, when you would like to replace your entire front driveshafts. βπ πͺ
The part number in question is #305335.
I often get asked, how often I replace the front ECS & rear CVD parts in my cars. For modified racing outdoors, the wear on these parts can be high. So I usually replace them in their entirety, or as minimal, the couplings and pins, every 2-3 races. For carpet racing, and spec classes in particular, these parts can last up to an entire season, especially if you maintain them regularly by cleaning them out, and by re-applying HUDY graphite grease ( #106210) to the couplings.
