I would stay away from the RS 5000's, I have had nothing but bad luck, with that particular model of shock. I would maybe consider the RS9000x, I haven't run them, but haven't herd anything bad . My last try with the RS5000's was on my 97' 3500, the fronts were leaking in 6-8 month of use, and I hardly use that truck (less then 5000 mile). I replaced them with BILSTIENS, and they have been good so far, although they do have a stiffer ride, I don't mind, but someone else might? Don't get me wrong, I have used meany RANCHO parts and have loved them (lift kit, traction bar,ect. ), but I just never had any luck with this particular shock. Just letting you know, good luck.
