I have a 06 LJ , 3.5” ACOS 5100 Bilstine shocks in front,3.5” Rubincon express coils in rear 5100 shocks and stock bump stops . I want To upgrade the shocks and change to 4” springs in the rear. Any advice out there?
Those are pretty good from what I've heard. It looks like with a 4" spring, you'd be ok with the ones that are set to handle a lift height between 3-4.5"
