First off if you're gonna lift your truck do it brand new!! Truck has 700 miles on it and every bolt came right off and the upper control arm didn't need pounded out or a fork used!! What a dream!
Second, my truck is a 2013 express quad cab 4x4 hemi with a stock height of 37" front and 39.75" rear (no sun roof or added weight from extras). I also installed 1/4" gorilla spacers to prepare for 35x12.5's on the stock 20x9's going on in the future. The stock measurements for the upper control arm and front sway are 0.65" UCA and 0.60" sway bar.
After the 2.8" lift the front sits 39.875" and the rear again sits 39.75". I'm not 100% sure yet but I might add a 0.75" rear spacer to get some rake. As of now though I think it sits perfectly level with the eye. The UCA now sits 0.90" from the tire and the sway is 0.80".
The stock tire being 275mm equates to 10.83". Going to a 12.5" tire it looks like ill gain 1.67" in width. Divide that by 2 and the tire should come in 0.835". For the UCA it should fit since it sits 0.90" away but the tire may rub the sway bar since it will be 0.035" over what's available. But now of course every tire is different and not all 35x12.5's are really 35x12.5 so we'll see.
Tomorrow ill get an alignment and remeasure everything!! But as for now it drives straight and true. Only thing noticed is the bilsteins are a little stiffer which you can feel going over bumps.
