Its working range runs from 9.40 inches compressed to 27.60 inches extended, with a 16 to 20-inch design height for tall suspension layouts. With natural rubber in the bellows, the spring measures 12.8 inches at its widest. Those heights and that diameter tell you the space the Firestone W013589370 occupies through its full stroke.
