http://www.summitracing.com/parts/UPI-3001/ is it just a straight up nut and bolt. I know the stockies have that dent in the side so they dont spin but it makes sense that is they dont spin you can align. thanks yall
Ok sweet. By looking at the nut shape could I just remove my flat sided stock nuts and grind them into this shape? Or does the precisesness matter? I mean 50 bucks is 50 bucks and I'd like to save it if I could.
well if your new control arms arent the exact same as your stock then yes this would help the alignment guy align your truck better.
but the real reason is ford installed a "D" shaped nut on the two bolts for your upper control arm. The "D" shape does not allow for exact camber correction. They can do a good job but never perfect. So to combat this you buy the rounded edge "oval" shaped control arm nuts and waalaa they can correctly align your truck.
