So I'm doing this to my 85: Replacing the springs with some take-offs from an 84, all new bushings, new, greasable 5.5" shackles, and some Rancho 5000s. No lift, other than the 1" or so from the shackles. When I yanked off the rear shocks on a 4Runner that I was chopping up the other day, I was surprised when the rear end jumped up. The shock was limiting the downward travel of the axle. That seems retarded to me- but what do I know? I already have all my parts- but now I think I need some different shocks so my articulation isn't hindered. I'm not building a crawler- but I want my suspension to work! What thinks you?
