I have been looking for a thread that could point me in the right direction in what i can do to prepare my jeep for a future 37 upgrade and i have yet to find it.

I have a 14 JKU, 2.5 RK max travel lift, 35 nittos, flat fenders (on the way), no regear, nothing special. I am wondering what can I do to prepare for 37s? i live in florida, so no crazy wheeling (Ocala would be the only wheeling i would do),but i do want to run 37s safely. This is also my daily driver that will see 17k+ miles a year. I would really appreciate the help and I'm sure many others are wondering the same question I am. Thanks!

You can make the stock axles work but depends on the wheeling you're going to be doing. If you want to drive fast offroad and do some rock crawling, you're going to break/bend something in your axle or the axle itself. If Florida is really as flat as people say it is, then I think you would be fine with the stock axles. However, at the minimum, get some C gussets.

I have been on 37's with stock axles for almost a year, it takes work to keep a jeep on 37's going.

balljoints are a must

I would highly suggest the full artec truss/LCA skid/gusset kit

brakes wont last very long

now I do wheel pretty dang hard and it has held together but I do feel a bit of the wear and tear on it has come from rough poorly maintained city streets.

I have almost the same set up and going to 37's as soon as the tires come in, Nitto Trail Grapplers.

I am not doing anything to the front 30, if it breaks I'll do something else or replace it with a 30 for a few bucks. They are all over the place.

I just installed flat fenders and it gave a bunch of clearance. Enough, don't know till my tires are on.

Just ordered adjustable bump stops form NorthRidge, MetalCloak, and will be installing them.

I don't do rocks, just trails, hills, some mud, and water.

I really don't see a problem with the 30, but we shall see.

Basically i would be doing light to moderate wheeling nothing major. I don't want to have to worry about something braking or bending so i could start saving up for axles. However, i have read that in my situation i really don't need to upgrade the front axles, only the back. is that true?

what would you do more to make yours ideal for daily driving? sound like you want to upgrade some more as well :)

I also have the trail grapplers. another questions should i maybe upgrade to a 3.5 lift?

i will have "saving" time before I go with the 37s i just want to slowly upgrade so when i do I'm already partly done with the process. I also do it right< i don't want to be driving down the highway and something brakes or always have it in the back of my mind something can brake. If i absolutely need and axle i will save. I have time and low expenses my only obstacle is the girlfriend haha

the front D30 is your weak link. the rear D44 is pretty stout as is. to run 37s and have it last even on the street id recommend regearing (unless your running 4.10s which you can get by with), and at least c gussets as mentioned before. Rustys makes a really nice simple D30 truss/gusset kit for under $70 that gives you some added rigidity where its needed most. if you look into wheeling it harder down the road look into sleeves, moly axles (especially if your gonna lock the front.)

truss, gussets, ball joints, upgrade steering, Heavy duty tie rod/ drag link/ trac bar.
Learning the hard way what DDing/weekend wheeling trips on 37's do to your jeep.
I've replaced every TRE in the front, unit bearings, brakes and it's a pain in the a** sometimes, but I wouldn't change it for nothing haha.

Yeah, looks like I'm going to have to regear. What would be ideal to gear to? Also any drive shaft issues when going to 37s?

I'm guessing if you have the new 3.6 it would be different?
I have 4.10 gears on 3.6 with 37's - not a problem at all. 4.56 or 4.88 are probably the best on the 3.6 and 37's, but I am really happy with the 4.10 gears for now.

Edit - Oh and by the way, my 37" Nitto Trail Grapplers are only 4 lbs heavier per tire than your 35" Nitto Trail Grapplers.

well I have this going on in my garage


but on a 30 I would do balljoints, 4.88's, truss, flipped drag link, gussets, synergy tie rod, control arms with heims at both ends, trackbar with heims at both ends.

and pray that the steering box lasts

If it were me, I would try to pick up a used Dana 44 for the front. You can probably get it pretty cheap from a used JK, someones take off or from a scrap yard. Then I would C gusset and get 4.88 or 5.13 gears.

Why throw all that money into the Dana 30 when you can save some more for Dana 44?

That's what I'm leaning towards. I just don't want future problems. How much do used 44s go for? Also just rehearing and a gusset will be enough?

Should I also upgrade to a 3.5 lift rather than my 2.5 RK lift
