They take quality _very_seriously.
I think it was shockwarehouse. Everyone involved was helpful. Maybe my springs just didn't work very well with them and they were working overtime. I have never been rock crawling and everything is pretty flat here. I am also easy on my equipment. The roads here are horrible though and I think driving on pavement is worse than driving off road.
Again, not trying to trash bilstein or shockwarehouse, but that's what my experience was and the cure to my Jeep's problems was mostly changing to the aforementioned Rancho's which do not leak and still work like when they were installed.
It was the bilstein's on the front end that were more problematic than the rears, although rears did give me trouble too.
Black Diamond springs are probably not the best. I originally had a black diamond lift and slowly replaced most of the black diamond components with PolyPerformance. I kept the springs because it's a simple spring and was not broken. Maybe if I had better springs the bilstein shocks may have lasted better?
I still have bilstein's on the rear for now but if they go to leaking, I will swap them out with Rancho's like I have up front. No need to replace something that isn't broken. To be clear, I did swap out the rear bilstein's two or three times, not just the fronts.
