37 or 38 inch tires?

Right, but at the very least you can keep the axles. Once you look at the cost of a new RockJock axle at around 10k a pop you start to think.
well aware. just dont want anyone to get the idea that running even 35s the right way is a cheap endeavor.

This is my friends ride on 38 inch TSLs. It has an 77 F150 44 with 8 lug outers and a 14 bolt in the back. It is running modded 7.5 inch RE long arm (not my choice) and IIRC a one inch body lift. For 38s to work without high lines it does not have as much up travel as I would have liked to give it considering the lift height and rear driveshaft length but compromises had to be made. This is about as inexpensively as you can do it knowing that if you want to do serious rock crawling the front axle is going to be a limiting factor.

Almost my build but I didn't use Rubicon Express. Still wasn't cheap.

I am no expert,just here to learn. I'm new to jeeps period. Maybe I will drop another 10-15 in it. Thanks Chris and lj for your expertise.
with your transmission, 4.88s and current axles you could do 35s at a realistic cost but go to a larger tire than that ... fuhgeddaboudit
 
Lost me when he referred to his first two CJ's as "Wranglers"...

I don't begrudge anyone for building what they want, and I do not care whether he breaks an axle or not. However, that thing on stock brakes is putting everyone else around him at risk.

Yep I remember reading about that build. Different strokes for different folks. But yes if you are going to something like that make it SAFE.
 
It comes down to what everyone is saying, if you want to go larger than 35" tires then you will need different axles that can handle the larger tires. And depending on the size you'll need deeper gears too.

As I said before on 33" tires you're more than large enough for most trails so just go out and enjoy it. Learn to wheel what you've already got and then slowly move up from there.
I did a TON of trails when mine was on 33" tires.

Brakes are really the only thing he NEEDS to change (unless it never goes over 35mph). He admits its an on road only Jeep. With those gears and a stock motor in 2H, even a stock Dana 35 is probably fine. Its clean and looks cool (in a cartoon sort of way). I'm glad he likes it.

I'd be worried even for a street rig. Heck even with my axles 40's are about the max I'd want.

Me too. But that's because of the way I drive. He says he babys it and his old CJs apparently survived his driving with big tires which is why I'm guessing he'll be fine, even if me and you wouldn't. Or not...
