Rancho lift questions. PLEASE help.

Mines over 7 with the rack. I think it's 7' 3"

Ours is with nothing on the roof the wife has to park in a parking garage for work so we have to stay under 7' too.

The Rancho Installation doc :link: says "N. The recommended tire size for this suspension system is 35” x 12.5”. The maximum wheel backspacing is 5 inches on 20” wheels and 4.5 inches on 16”, 17” and 18” wheels. For 37” tires, trimming the fender is required." There is also a figure that illustrates how backspace is defined.

If you plan to wheel it off road, I'd recommend the smaller rim diameter to get more sidewall and less potential to damage the rims. Therefore, my first choice would be 16", followed by 17" and 18". Keep in mind the tires will stick out about 1.34" more that with stock backspace (I have stock 5.84" backspace with 315/75R16 tires and they stick out a little, so photos in my build thread). Going to 20" allows 0.5" more backspace so it would reduce how far the wheels stick out of the fenders from 1.34" to 0.84".

Thank you very much. This information is greatly appreciated. With the wheels sticking out 1.34" more than stock, will the tires stick out even further than that since 35x12.5 are recommended?

05Mudiak: Great looking H3. Why 20's instead of 17's or 18's?

Its what the wife wanted and its her 3. There is still a lot of side wall a inch less than a 18 and we have yet to hurt the 20s off road but we try to avoid bashing rocks. Plus these km2s 325/60 are closer to 36

heck I was trying for a16" but it had 20s on it when we bought it and she liked the way they looked
