Hey guys, I've been researching all day about spring codes & can't seem to find the answer I'm looking for. According to the data plate inside my 1994 F-150 4WD Extended Cab, my spring code is "L4I". I know the L is the code for the front springs & I found what that means. I know I'm supposed to ignore the middle number, but I CANNOT seem to find ANYTHING on the code "I" for the rear springs. All the tables I find go from "H" to "J", leaving "I" out. Does anybody know what's up with this or what rear springs my truck has from this info?
Thanks in advance, Hawkbyrd

 

did you ever figure this out? I have the same question.
