2019 Laramie ORP, BDS 6" IFS with BDS UCA's and Fox rear shocks. Nitto Ridge Grapplers 12.5 x 35. Fuel Vectors 18 x 9 Zero offset 5" backspace.
Several notes...
1) When I lifted mine, BDS was the only one that allowed 18" wheels (v 20's +) on a 6" kit. I went with 18's because on wanted more sidewall on 35's.
2) I discovered in the process not all rims are alike on clearances. My first choice of rims (same published size, offset, backspace) would not fit because they didn't clear the brakes. Probably not an issue on 20's. Very happy with my 2nd choice, however.
3) The BDS kit replaces the rear springs. Therefore, it's recommended on ORP's that you leave out the preload spacers on front to achieve a level stance. I'm about .5" high in front because that did not get communicated to the Tech that did the install.
4) Even though 5" backspace works, my tire is very close to the steering knuckle. It's been ok in mud and snow but I haven't tested it when aired down during more serious off-roading. Thinking I'll be ok but it might rub if the tire bulges toward the knuckle when the it's flexing against a rock. I refuse to install wheel spacers so don't go there
