OK heres the deal. I've heard the RS9000's ride great so I ordered a set for my truck. The tallest they make is for a 4" lift. My truck has a 6" lift. I ordered the 4" and had my cousin who's a machinist refab my shock towers so they have 2" of drop, that way they should be perfect for a 6" lift. After bolting in the bottoms I thought they looked short. I extended them and measured them and they're 3" shorter than the Rough Country Nitros(for a 3" lift) I just took of. WTF? I still have my stock shocks and after measuring them, they are 1" taller than my stock shocks.WTF? I immediatly called Summit and said hey you sent me the wrong part. After checking and rechecking, the rep said that's the right part # for the Rancho with a 4" lift. I then went to Rancho's web site and confirmed it myself. They're so called 4" lift shock measures only 1" longer than the stock shocks. I'm calling Rancho Monday morning and asking them what the're deal is to say the least. :rant: Buy the way,anybody want to buy some shocks for a 1" lift?
