I ordered 4" & got 5". I didn't figure that out until I called Marlin, and gave them the number off the spring. They were already on, so I just stuck with them.
I have a question for you. On the 1st page you said you ordered the 4" but here on the 3rd page you said you have the 5" springs. Did you end up changing your mind on the springs or did you try the 4" springs?
I'm looking at 37s for my 87 pickup and it seems like 4" suspension just won't be enough clearance for the 37s without major cutting. Cutting/pounding isn't a big deal but I'd rather not have to cut out too much
