It really is a disappointing site.After we get done wheeling the 38's go back on as quick as I can get home .
I went from 32's to 35's to 38's and by far I like the looks and ride of the 38's on the highway up to @80 mph after that it starts to shake a bit .This weekend we ended up driving a round trip of a little over 450 miles on them.

Dewayne I have a 4" Rough Country lift and run 38" Mud Grapplers on 18"wheels .But I did have to trim fenders and cut the rear pich seam off and put a piece of 2" square stock for rear axle bump stop the Jeep. They are fine for light wheeling and as daily driving .Because it dosent leave alot of room to flex.

Daughter driving.
When we want to get rougher I have a set of 35" Hankooks on steel 16".Have alot more room to flex and dont worry about the axles as much.

So if you can swing it I would say get 35's on steel and 37'sor 38's on a nicer wheel.Its worth it !

sub308 So even with the Dana 44 up front it will still be a major pain to run the 37's?

Heston22 I run 35"s with 4" ruff county 0 problems looks great with no rubbing and no need i'n change of joints and drive train no matter what the opinion of other are! Went to dealer and other mechanics not enough of stress being placed on them to do any harm!

thaduke2003 Jake, that's the Lower 40, by Mopar. No suspension lift at all. Just a one-off body kit. Pretty gnarly stuff, that.

Sub, I run 35's on my daily driver with a 3.5" Rock Krawler lift. It only rubs at MAX travel (35+ degrees off-camber, obviously with swaybars disconnected). With the Bilstein 5100 shocks, it flexes like mad, drives like a champ, and is 100% streetable, even on 35" KM2's. I love it. It's a bit extreme for most folks.

For a DD, you'd be NUTS to run 37's. 35's are still pretty huge, even for a JK. Building a rig for 37's adds a whole other level over 35's. It's your rig, and your money, but I say stick to 35's- you'll thank me when you don't bend axle tubes every other weekend! Mark W.

sub308 Yeah that is the only reason I am leaning away from 37" and towards 35" because it is my dd. But I think if i get 35" I am just going to want to get 37" later. So I would rather do it right to start with.

JeeperJake Saw a youtube thing with 40" Jeep at the yearly fling in Moab.

They 'said there was NO suspension changes'!!! I can't believe that.

Looked great but can not see such extremes for MY daily driver.

sub308 Thanks by chance are you running 37s if so do you like your lift and/or can you recommend a good 4-4.5 in lift?
09-05-2010 04:53 PM
thaduke2003 I know plenty of folks running 37's on 3.5-5" of lift. 3.5-4.5" and you'll likely need to trim the fenders.
You'll definitely need to re-gear, and you'll need a programmer to adjust the computer/speedo. 5.13's for a 6-speed, and 5.38's for the auto, in the JK. I also HIGHLY recommend the Superchips as the programmer.

Beyond that, if you're running a non-Rubicon, you'll want to swap out your Dana 30, or at LEAST beef the HELL out of it (trusses, sleeves, C gussets, etc.), or it won't last worth a damn.
Also, at that level, you'll obviously want to add front and rear lockers (push-button).

You'll likely want hydro-assisted steering as well, as factory steering craps out fairly fast with 37's.

Beyond that, there's always something else to buy! Mark W.
