Just curious if I could do a spring flip with my current 4 inch lift springs and clear 37's? Anyone doing this?
Anyone running 37's with a SUA?

I was running SUA and 35's, but they eat your fenders once the springs are compressed off-road - front and back!! I've now chopped the rear fender and having some extended bump stops fabbed up for the front. I normally run 33's for daily driving.

I have been looking into this as well. I have the old 35's from my 4Runner that I plan on running first to see how they fit. I am setting up my suspension now with spring flip for the rear, 4 inch spring and 2 1/2 in shackles. I will be doing flat fenders as well, might trim down the aprons a bit and lift fenders up a couple inches to help. The rear I get the feeling staying SUA is going to require more trimming than the PO already did. I do not want to do a full comp cut so we shall see. I will be following your progress to see what you do and end up with.

Very nice. More pics please.
I am running 37" super swamper boggers off road and 36" michelin 16"-9" military tires on road I would just scrub on the front if twisted the same was true for the rear how ever I have a hard time keeping springs in the back due to the weight of my 40 and the amount of off road use it sees. I am was running a BDS 4" lift with 1.5"-2.5" "can't remember" anti-inversion shackles the rear didn't last long, which they told me was due to the torque of the v8. However they did honor their warranty but had to give me a set of rough country springs as they don't make the kit for an FJ40 any longer, the new springs did not last near as long even though I have since put a diesel in the truck and were quite lower then the BDS springs to start with. I have since built new front fenders and rears the rears are cut out as well but I will be calling Alcan on Monday to finally do this correctly with SUA. Hope this is of some help.

I have a '78 with 4" lift springs w/2.5" shackles rear, 1.5" shackles front. I run 34x9.50 Super Swampers and have never had them rub, though the rear tires are close when compressed. Would like to move up to 35's or 36's, but know I will have to change something to gain more clearance...especially in the rear.
35's SUA, stock axle, stock springs, extended rear shackle - the right front is jammed on the fender, the right rear is hanging in the air - the left rear is tight up against the rear inner fender. Left door won't close, right door won't open in this position!
