Im confused. Some sites like SSD say a firestone 9000 is 4.5 in. compressed and 12 in. extended.Firestone's website lists the 9000 at 6.25 in. compressed and 10.25 in. extended.
http://www.fsip.com/pdfs/RR/8196.pdf page 33 What specs should be used? Im thinking about swapping a pair of RE7s that are over the axle of a Colorado for a pair of 9000's to give a better ride. I just have to make sure I have enough room. 4.5 probably. 6.5 NO WAY...
