Like the title says. I currently am running 35's with the following suspension mods.
Teraflex 2.5" budget boost
bilstein 5100 shocks (2-3.5" versions)
rough country 1.25" body lift.
jks front discos
poly performance front lca's that are 1/2" longer then stock.

What I want to know is what suspension mods do I need to do to clear 37's in the future?

 

Flat flares, bumpstops, gussets, pinch seam trim?

 

More money! That's the most important thing you need. Lol

 

What is the cost for gussets mentioned? I thought 2.5 lift with minor fender trim will work fine with 37s..

 

The gussets are for axle strength not suspension. I already trimmed the rear wheel well pinch seam a little. I want to keep the stock flares.

My initial thought was to replace the 2.5" spacers with some 3" lift springs? That might get me the hight I need. Just not sure what else would have to be done with the springs..... ie drop brackets, adj track bars.....ect

 

Your current suspension will work.You need to look at axle upgrades,gears

 

Gussets and either an axle truss or axle sleeves..... Possibly a re-gearing is in ur future

 

ya I know there is axle work to be done....this thread is about suspension work to clear 37's

So the opinion is a 2.5" budget boost and 1.25" body lift should clear 37's?

 

Depending on how you are set up you may need another inch or so of bumpstop. I agree with the others to put the money in new rear axle shafts and proper gearing.

 

we'll for axles i was planning the following:

front:
G2 Core44 front axle (if they ever release it) with 5.13 gear, ARB locker, and Cro-Mo shafts....not sure what axle shaft splin count options there are 32,35? would like to get the biggest available for extra strength

rear:
ARB locker, 35spline Cro-Mo shafts and matching 5:13 gears


all this on a 2dr with 37's should be a formidable trail jeep?
