My question is what is the roof height of you guys running these combos? I do 90% highway, is there a big difference in mpg with 4" and 35s and 6" 37s?
Currently have Bils 2.8" rear .75" stock tires
If your garage is 84" I can tell you what will fit in providing your garage door opening track rail is higher (which it should be)
My garage opening is 83". So a hair short of 7'.
I was able to fit my truck in height wise (length wise is another story and why my truck is outside) when my highest point of my truck (sat antenna) was 82.5"
The set up I had was
- 6" RCX
- Bilsteins at 1.4
- 325/60/20 tires, which is an over sized 35" at 35.4"
Going back to you...
A 4" RCX is 1.375" difference in height over a 6" RCX lift.
So a 4" with 1.25" body lift will be a 1/8" shorter. So practically the same thing.
If you go the 4" route, you'll need to drop your Bilsteins either to 0 for slight rake or 0.7 for near level.
Going back to my measurements, you'll be 0.8" lower and you'd be able to fit.
Now not all trucks are created the same height.
My truck stock was 36.25" in the front and 39" in the rear which is avg and you'll more than likely still fit.
As for mileage.... What gears do you have?
37's are definitely heavier over 35's. The weight and rolling resistance will greatly impact your MPG. So if you're worried about that, stick with 35's.
If 35's, I'd do without the body lift and just rock your Bilsteins as the settings I mentioned and the 4" lift.
True 35's are really 34.5"
Bht MPG will depend on your gears and tire size.
If 3.55, stick with 35's and don't think about 37's, if 3.92, I'd still recommend 35's but your truck will still have power to rock 37's. Just expect again an MPG hit
Hope this helps.

I've assisted and helped on MANY of the lifts on the board and personally have my truck lifted at all heights. LOL
