So, just curious, do you ever get stopped for tires sticking out too far beyond fenders, and no bumper in front of front tires? Where I live, it happens…

Just picked up my JTRD today. 37’s with stock 3.73 gears. So far, I really don’t notice the difference from stock. I’ll post a reply once I have more miles and fuel economy data, but so far I think it’s unlikely I’ll void my warranty with a regear.

Do you have a lift?

I.T.
What I saw on a Youtube video this past week, was this formula:

(desired tire height in inches) times (current gearing) (divided by current tire height in inches) equals the ideal gearing.

Example, I have stock Sport-S tires, they are 30 inches in height. I'm wanting to upgrade to 33 inch tires.

33 X 3.73 / 30 = 4.103


I'm guessing that there are caveats to this though....I've been told in another thread I opened that the 3.73 will be just fine with the new 33 inch tires when I get them. I guess I'll see.

Looks great and proportional. How much lift and offset?

Where’d you get it if I may ask?
Thanks man!
I wanted the stance just right. I don’t like too jacked-up or a bad rake.
2.5” Clayton Overland Plus. Offset is 0mm (4.75 BS).
Install was done by Locked-N-Loaded 4x4 in Collegeville, PA. They only install Clayton. Nuthin else ;-)

Yeah you nailed it. Is it a diesel specific lift?
What was the turnaround time? I’ll be going up there (hopefully in a month or so) to pick up a gladiator and it might be worth a quick stop if they’re not in Western Pa.

If you put a Ford in your driveway you would not have to keep changing trucks. Buy a Ford and your done

Joe is the owner. If it’s just the suspension, wheels and tires, then it can all be done in (1) shop day. That equals $1,250 for install + $200 for full alignment. This shop is LEGIT and Joe has integrity - short supply these days.

3.73s seem just fine for my 39” KM3s. It’ll drop to 7th on a steep climb but it did that on stock tires too. Getting 22-23mpg combined
