Anyone run bbc's with marlin's 4" springs? If so what size shock did you run? On my 90 extra cab w/o a body lift, I am debateing if I can even fit the 13"s without a whole lot of inner fender hacking.
Seems like marlin recommends the 12" 5125 Bilstein with this spring. Extended length = 29.70" and Collapsed Length = 17.91"
BBc
Extended Length Collapsed Length
15" = 36.43" - 21.46"
13" = 32.69" - 19.51"
11" = 28.09" - 17.11"
The PO had rears up front with 14" pro comps. which are beat to death. And like terrible. not to mention he never mover the power steering box forward.
