Not to my knowledge. If they were a pair of light duty rubber gloves, they could be made more pliable. But these bags support the weight of the car and do double duty as suspension springs. Constant use will keep them from drying out, but when they wear out, they wear out. Time to remove and replace.Is there any chemical, treatment or technique that can be applied to a good set of bags to prolong their life?
I believe Eddie of American Air Suspension mentioned once that liberally applying a good quanity of silicone protector on the bags would help them resist dry rotting. So thats what I try and do once a year.
