So far, I've had no issues whatsoever on the fronts. Going to leave the whole front end stock, other than having removed the fog light section of the front bumper.
The rear seems to be the issue to focus on. I've got 5 different bump stops coming from Amazon in the mail... Going to add 1" to...
After running this set up for two months; in the Mojave, dune running, woops, etc... on the Rubicon, on the freeway and all things in between the set up has been fantastic.

I hit a good chunk of Rubicon Sunday with @JohnGalt on camera work, via Wenthworth Springs and the old entrance. The set up worked amazing. A little tire rub on the rear bumper at one or two points during the day but with 39's and 2/2 hypercos it was a much better run. Watch my debead at...
Continuing on my heat testing "stuff" :)
--Running east on Hwy 58 out of Bakersfield:
At 85 deg F
Cruise set at 70mph
235 max coolant temp
195 max transmission temp
Both well within range and easy cruising
--Dune Ripping!!!:
At 90 deg F
Baja mode; 2wd; no lockers; spinning as many donuts with...
Pretty similar to stock honestly. But using forescan to adjust for ride height is an absolute, otherwise your rig will think it is jumping and that creates a harsh ride.
Tire pressure will also affect the ride but all in all I've no issues and am happy with the set up.
C sidewalls will be your only longer term issue. I used the stock tire set up for ~25k miles on lots of rocks and trails (rubicon type stuff) and no tread issues.
I just recently upgraded to the ko3 with d sidewall.
I just finished a pretty long trek from Sacramento to the Mojave, camping for the week along the way and home with @JohnGalt. Balance seemed fine throughout. Not as good as the stock 37's or smaller tires but not bad either. Nit picking.
When I first got the 39s, there was a shimmy. I took...
OK. For reference purposes:
I ran the Donner Pass yesterday between Sacramento and Reno unladen in My F-150. Again 2019 with 3.5 EB and max tow package.
At ~60 deg F
Cruise set at 70mph
223 Max Coolant Temp
205 Max Transmission Temp
Both WELL within range and nothing to be concerned with...
Coolant below 230 I think is fine and you probably won't see above 223 very often.
Correct, once you hit a "slightly" higher than typical temp the numbers will pop up. If memory serves 223 is the number that pops up for coolant, can't recall the others.
Tranny I'm drawing a blank on. Not...
Solid question. I used forescan to put the numbers directly below each gauge on my '24 braptor to have a better feel. I've learned a few things. Separate coolant temp from engine oil temp.
For a reference point: I've used my '18 F150 with 3.5eb to pull quite a bit of horsies, circa 10K...
