Details coming when I have time. Between tires and 1.5” spacer lift, 3 total inches gained. These 37x12.5x17 KO2s are actually 35.25”
Looks great! What is the overall height of your rig now with the lift and the 37s?

Looks awesome! And THANKS for the straight down the side shot, to see how far your wheels stick out!! Any chance you could share the width and offset of your new wheels?

With the 1.5” teraflex spacers (1.5” spacer in the back, 1”+0.5” spacers in the front and 37” KO2 (actually 35.35”) overall height at rear corner of hard top is a hair over 78” (~6ft 6inch).

These are the original Mopar Beadlock wheels. 17x8” with 4.4” backspacing wrapped in 37x12.5x17 KO2s

I’ll also report, got up to 80 by mistake on the Highway today on 37s and heavy beadlocks, easy as pie. Hit the speed before I knew it. Smooth; engine wasn’t stressed at all with the task.

I see no need or want for re-gearing for 37s.

Thanks for measuring the height! Was the acceleration noticeably different after going to larger tire?

In my opinion, the change in acceleration was not noticeable during normal city driving.

Did you have to use wheel spacer’s on the wheels/37” ko2’s? Any rubbing at full turn? How about fender rubbing at flex especially in the back?

No wheel spacers. Just the lower 4.4” backspacing of the wheels vs the 6.125” of the stock.

No rubbing at full turn. Not even close, still have 3-4 inches from contacting at full turn in either direction from my eye-ball estimation.

No chance to flex yet.
I went with the longer teraflex bumpstops, 1.5” instead of 1” spacers and BFG knowing they ran small to try to avoid rubbing.
Will let you know when I can flex, may be a few weeks given family obligations and work.

Thanks for taking the time to provide all this "intel" Eli, much appreciated!

Also, would it be safe to say then, that a 9" wide wheel with the same 4.4 backspacing would stick out roughly about 1 inch further than what I see in your pics? (Assuming similar tire dimensions)

(Sorry to be such a pest, just trying to make sure I'm finally grasping all of this correctly)

Because BS is the distance from the inside face of the wheel that bolts to the hub to the inside edge of the wheel, if BS stays constant, any additional wheel width would be from the inside face of the wheel that bolts to the hub outward to the outside edge of the wheel.
So a 9” wide wheel with the same BS as a 8” wide wheel should “stick out” an inch further.

Someone please correct me if I’m wrong, but this is my understanding from looking at diagram.

I'm pretty sure you are correct, I was just looking for confirmation as well, so I don't screw this up! 😄

Sorry again for being such a pest, your feedback is very much appreciated!

How much room is there with the spacers and the 37's? Is there enough room to fit some of the larger 37's out there with the stock wheels and just spacers? Glade you see you finally got yours, can't wait to see it after the diet!
