37's on Dana 30??

Hey guys.I am planning on ordering a JK in sport trim. I know they come with dana 30's but honestly I plan to re-do a lot of stuff (re-gear, new interior, different fenders, tops, tires, wheels. and i don't plan to rock crawl or heavy duty off road anymore so I see a RUBICON as investment I will not see returns on, (I have destroyed one or two trucks already, mostly Toyota's) so this will be a pleasure off road cruiser.

but part of the "look" I am going for is a tall lift and big tires ( I know, total poser) but I really am tired of fixing my ride every weekend as I am 46 and have lots going on in my life and fixing broken parts is pretty low on my list anymore.

so will a JK sport handle 37" tires?

and what mods will I need to consider to run them?

someday if the bug bites again, I'll upgrade, but the sport is where I am starting.

any help?

You'll be fine. C-Gussets, sleeves, and shafts aren't a bad insurance policy ...but lots of us have run 37s on stock D30s with no issues.

Running Poly Performance sleeves and gussets on my 30 with 37s.

Lots and lots and lots and lots and lots and lots of other threads about this too but I know our search feature kinda blows.

Google searching JKOwners.com + "what you're looking for here" works pretty well if you're ever tempted to punch your monitor while attempting to search the forum. LOL

Definitely c gussets. Everything else will be okay. You don't really need shafts or sleeves with light wheeling.

The sport will handle 37s no problems. Re gear, 3-4 inch lift, add some Cs and you will be good to go!

Check out the purejeep backbone kit. It is a great thing to have welded on the passanger side tube to reinforce the housing. This is what I bought....http://www.purejeep.com/proddetail.p...=PJ5155&cat=10.

Includes the backbone as well as upper/lower c gussets, CA skids and track bar mount gusset. I am surprised more people do not recommend this kit honestly, its great. From what I understand, a truss adds much more reinforcement than an inner sleeve. My 2 cents. Good luck!

I threaded a similiar situation a while back. I wanted to do a Rubi with 40's on a 2 door. I also will use mine as a family fun toy. I got razzed for wanting to do "the look" but also got alot of good advice here, I will do 37's now. C gussets from EVO, PP or PJ can't hurt for the price. Gearing I've been told for a mall crawl'n 2012 3.6 with 37's can be 4.88 or 5.13 depending on how much grunt on the low end you want. The new engine has enough added power that 5.88 aren't necessary for what you want to do. A short/mid arm 4" suspension can fit 37", no sense going longarm with it. I too want to change the fenders so depending on what type you go with you may even get away with a smaller lift or even no lift at all. You'll find a wide range of lifts and $$ from 2"-4" lifts so look & read what rigs on here are using & let your budget be the judge. Good luck with it!!

This x100, plus don't touch the throttle and you might not break that shit.

Sure it can be done..... but I wouldn't!

My personal opinion based upon your wheeling style,would be to get the Rubicon and not worry about anything other than some gears, tires, wheels, and a lift. You will get the strength needed to run the 37s (oh yeah.... those above recommendations on how to add beef still completely apply to a 44).

Most people are stupid like me and tend to under build, then spend more and more to get the right setup.... don't be a dumbass like most of us, do it right the first time!

I've been running 37's for two years now, I've only broken two U-Joints. I wheel my Jeep like its a Rock buggy! Axle is still straight, however I've also strengthened everything I could....still run stock shafts too! So in my opinion you'll be fine!

Wow. Your a madman. Keep us all updated on how that goes.....if it can handle 42s for an extended period of time.....then it is certainly a much better axle than I thought. I sure hope it can, but.....slightly skeptical about 42s to say the least.

no way 42s will last on a 30 unless it doesnt see trails at all.

I have a d30 up front with an aussie locker, 5.13s, C gussets, LCA skids, and Nitro cromoly axle shafts. I plan to add a custom truss soon and run 37s or 38.5s.

I had to get the aftermarket shafts after my axle shaft grenaded on a trail. And I am running 35s. Fact of the matter is, it might last for you, it might not. I am a very careful wheeler, i chose my lines and am light on the throttle. Nonetheless, I came down just the wrong way off a rock, heard a lout bang and clunk, and bam the axle shaft had sheered off the ears at the u joint. And get this- the ujoint was still in tact. Go figure.

Point of the story is...build it up to handle 37s and you will probably be fine...but theres still a chance for failure. Hell, I've seen guys with stock wheels/tires destroy an axle because it cracked on the passenger side tube. It is what it is. Good luck on your decision.

I would go with the purejeep kit. A long side truss, or in this case a backbone brace, which is essential a double sided quarter inch thick truss, is stronger than an inner sleeve. Just saying

I like the looks of that Purejeep...nice and simple, but the T&T truss looks beefy...more involved as well though.

Agreed. With mine I put in RS-E inner sleeves and cut down the outer sleeve to essentially just support the long tube side and work with the Poly LCA skids as well.
