Offset is a derived value. Backspacing is what determines how far your tires stick out. (or not....) Larger value for backspacing will probably let you clear the control arms, but, you will be more likely to rub on the front/rear of the fender liner, or body parts.....

There is no factory level kit. Do you have the Off-Road edition? (that came 2" taller than the run of the mill trucks, but, it was springs that gave the additional lift, not spacers.)

To properly clear those tires, (35"......) you need a total of five inches of lift to do it "right".
