The axles will be the least of your problems. With 7.5" of lift, I'd strongly recommend some additional wheel base. That thing'll be really squirley that tall as short as TJ's are.

The weight of the axles won't put much drag on the vehicle. OTOH, bigger tires will necesitate much deeper gears. I'm assuming you're going pretty big with that axle. Anything less than about a 38 will be hoing rows on most trails.

 

What motor & trans??? I also agree 7.5 is WAY to high for a stock wheelbase Jeep.COG>flex IMO.

 

I have a 00' TJ with a Waggy 44 front and a D60/Detroit rear, 5.5" RELA that I 4-linked and maybe 1-2" of extra wheelbase. Both axles are stock Waggy width with 4.56, I have the stock 4.0, auto, and 37" MTRs. I drive mine daily with a 186 mile roundtrip commute every third day to the fire station and 195,000 miles on the Jeep. I still love driving it and not looking forward to getting a DD but gas prices has me looking at a little Tacoma. Its doable but then again in my 12 years of driving I have owned a built YJ and this TJ so Jeeps is all I know. Just remember its a Jeep and not a Caddy.

 

So you think if I increase the wheel base about 2 to 3 inches I should be fine? The 4.0 and stock manual trans. I would like to run 38's.

 

A 44 front on 38's is going to be pushing it anyway. Other than that, I'd consider more like 6" for that much tire, but that's just my opinion. There's guys out there with stock wheel base and 40's. It's all about personal preference.

 

Hey Dodgen, do you have any pics of your setup? Did you add any wheelbase in front or just the back?

 

No reason to go to the 7.5" RE....

Run a 5.5", I mean those RE kits all sit way high so you get some bonus inches there.

37''s / 38"'s run fantastic with the 5.5" RE kits and stock WB. With the 14 bolt, you will or should have plenty of width going on.

 

I run 7.5" RE coils on an unlimited stretched in the front 1.5"s and 42's. I am actually about to put the 5.5's back in it to get my COG back down, as stated above the RE 7.5's are ridicoulously tall!!!!!!!

 

lockedupLJ do you have any pics for your rig?

 

Ummmmm, yeah, follow my sig, look in southeast photo's blah blah they're everywhere. If you need something special just ask.

Not being a dick or anything, but just got back from Chili's and it was 2 for 1 well drinks sooooooooooo.

 

I have a YJ, but I do have 60's. The drivabilty for me actually improved....in part I believe because of the weight increase. It feels more stable, not so "jolting" on the road. The wider stance probably helps that too. I daily drive mine.....

 

If you're going that tall, definitely stretch the wheelbase. That thing is going to be tippy.

 

So you guys think the 7.5 RE is too big for 37 or 38. I would like to be able too flex too.

 

I think so. I will try to get some pictures up when I get home but it will be a few days. All my pictures are on my home computer. And with my 5.5" lift and 37"s with minimal trimming and a 4-link I flex pretty good without getting into the metal. Good enough for the springs to come out and add a limiting strap.

 

I am running RE5.5's in the front and the 4.5" in the rear, sits almost level. 37" MTR's with 2" spacers on each side. Fronts will just kiss the Hood (no front fenders), the rear i am using the bumpstops that came with the Kit origionally.
