Stretching won't make fitting 37's at low height any easier. It simply lengthens your wheelbase. Stretching requires more cutting, measuring, cycling, etc.

Vengeance was a build beyond what most of us will ever do, and for the record the body was lowered on the frame if I remember correctly. And it's on 40's. not a fair comparison.

 

if you want to do this setup on the street you'll rub at the pinch seem.

i wouldnt take this setup off road unless you trim the pinch seem, the rubicon rails, and trim your fenders.

with 2"of lift and stock fenders, youre going to have absolutely no uptravel because that tire is going to stuff the the dongles out of your fender. ask me how i know

 

A couple things here.

37's is a ton of tire for a 2" lift and will require more cutting than you probley are comfortable with. However if you go any higher than a 2" kit, you will need to address the front driveline. You can either replace it or install spacers. However spacer do nothing for the operating angle of the driveshaft at the transfercase.

The real question is, What is your plans for the jeep? Wheeling, looks or both?

 

I had a 2" spacer lift with 37" iroks. Trimmed the fenders and the pinch seams no problem with the driveshafts only issue was even with them trimmed if you are running the same bump stops the rear tires will still cut into the rear where the pinch seams are if you are doing any hard off roading just be aware but you can do it

 

..what are bumpstops for then?

 

I'm not understanding your question related to what you quoted?

Bumpstops serve two purposes. Keeping the tires from eating themselves on sheet metal and fenders, and prevent you from bottoming out shocks and other suspension components.

 

Someone before you said something about well vengeance is stretched. So I said run the rock krawler stretch 2 door kit. Then you went on a rant about it not helping anything being stretched. Bumpstops, flat fenders and a 2 inch lift and you can run 37s is what I am getting at.

Tone seems to get lost in text, so sorry if you thought I was ranting. In my very first post I stated that with flats, 2" coils, proper bumpstops, and reasonable trimming of the sheet metal one could easily and successfully run 37's on 2" of lift for all applications, DD and trail use. Right from the start.

Next you pointed out vengeance, which someone followed with stating it was stretched. I felt it was necessary to point out that that is not a fair comparison, especially since vengeance has significant body alterations such as high line front fenders and a comp cut rear.

Adding a stretch to the equation for the OP does not make the answer any simpler. A stretch is extremely useful in terms of rear departure angle and vertical climb capability, but requires significant body alteration.

To the OP, I you want to run 37's with 2" of lift, you can with a quality 2" coil spring, likely stock control arms all around (maybe adjustable front lowers for caster correction), flats, proper bumpstop extensions, appropriate length shocks, and some sheet metal love with a cutoff wheel and grinder.

Shit, maybe I am ranting now...

 

4" lift. Flats. change both driveshafts because they are better.
