Oldguy, besides the fact that they lose some pressure a month or two after they have been recharged, and they have to be recharged every year, and they are too soft, no, no issues at all. LOL. Lets put it this way, I am running stock, non rebuildable, Ryde FX front shocks this season. Now, that being said, I could have installed the Fabcraft air chambers on to them, and it would have made a big difference, but I guess I am sick of dealing with them right now.
They are for sale if you know anyone who might be interested.
