TJ with 35s which modifications needed?

Hey Guys,
I'm new to this forum, have been reading quite a bit but now I'm actually having a question regarding requirements about a modification what I'd like to do to my TJ.

I'm running right now a 4" suspension lift with 33x12.5 tires and I'd like to go a little bigger towards 35x12.5 and if needed put a slight body lift on it for clearance.

Did anybody run this set up already with the original dana 30/35 axles in it?
I was thinking about re-gearing those and put lockers in them due to the fact that dana 44 rubicon axles are gold platted and kinda priceless.

I would appreciate any tips and thoughts about it.

Thanks
Matt

Welcome to the forum. The first thing you need to take care of is the rear axle. You do not need a Rubicon axle, but just a Dana 44 from a TJ. Going to 35s on a Dana 35 is a losing proposition unless you never go off road. The only other way is a Super 35 kit, but they are pretty pricey too.

Do not under any circumstances lock a stock d35 u are already pushing the limits running 33s on that turd axle and locking it and then going to a bigger tire on top of that is asking for a mess.

Thanks for the first thoughts.

Okay so sticking with the stock axles isn't an option in this case.

In this case I may should consider staying at 33s until some nice axles cross my way I guess...
How is it about the dana 30 in the front?

Thanks
Matt

The front axle will be completely fine up to 35s. Locking the rear is not a good idea, but if you drive smart it can be done. I had a locked Dana 35 for a couple years although I ran chromalloy shafts and I mostly offroad in Moab. Just look for an axle and eventually one will show up.

Okay thats for sure something what sounds not that bad, then I will keep my eyes peeled for a rear dana 44 and after that I'll think about the tire upgrade...

What else could you guys think about what will cross my way with that upgrade what I would not have on my plate right now? I'm quite sure there is something...

Thanks

Depending on ur lift and set up, sye, a dc driveshaft, upgraded steering and brakes, adjustable rear upper control arms, regear, body lift if u want clearence, and that's what I can think of off the top of my head

I will say that I bought my rig from a dealer that had a bunch of modifications done to is so he could move it off the lot. One of them was 35" tires as well as a lift. To my knowledge, the rear axle was not switched (I have the invoice for all the work they did).

I run light trails but mostly highway and I have not had any problems with it in the year that I've owned it.

Obviously as I read more about this I will one day try to replace it but it seems fine for now for my purposes.

A ford 8.8 is not very pricey. Half the guys I run with have them. Also you could go for flat fenders for even more room. I am running a 4" lift with 1" body and flat fenders. That's enough room for 37s. Just depends on how much flex you need and the wheeling you do. And the front axle I'm running a 97 dodge ram 1500 dana 44 front axle. It's perfect for my 37s. And was under 1000 to put under my jeep.

the jeep dana 44 is a hybrid. They ram 1500 is a true dana 44. It is about an 1" wider on both sides. My buddie orderd the brackets from a place he knows. I will ask him where. Also people say the axle sucks cause of the split shaft but yukon makes a delete kit for that. I am out of country for a few more weeks when I get back i can post some pics. But by far I think it is the best junk yard front axle you can get. I mean look at guys with the 1500s. I have seen them run 38s with all that weight and power. Under the jeep it should be pretty bullet proof. I guess i will find out.

Vt: its to hard to explain. But just type in rear jepo tj dana 44 on google and it will pop up. Thats how I found out I didnt have a 44 lol they are not rare so its a good chance you do.

Tj98: I have a 9" that a buddie is currenty building while I am out of country. If the measuring tape is good they sould be very close to eachother. And im haveing to buy new rims so I will get a shollow back spacing.

Match up the cover on your rear axle. Also the D35 has a rubber fill plug while the D44 is steel.

Sure looks like you got a winner. All you need todo is build the front axle now lol I would just do a super 30 kit. They work good just don't lock it.

I ran this setup, but my super d35 fail in 4 months.. the rear geear and the rear arb fail, the shafts was ok. Now i swapped with 2 d44 form a wagoneer.. i wouldn't put a fornt locker with the d30.. could be a good thing change the brake system with some more powerfull..
i have to change the steering system with a heavyduty one..
if you don't do offroad you can stay with your axle, but if you do offroad prepare yourself to spend a lot of money to change the all jeep...

At the most for a locked set of 35" tires, I would suggest some chromoly axle shafts and some spicer 5-760x u-joints. Even less to worry about if you have light 35" tires. For example, 35" MTRs weigh 67lbs-ish and the Toyo MTs weigh almost 20lbs more per tire.

Cutting the weight of the wheels and tires makes a big difference in all around performance and durability. I got my 98 wrangler with a d35 and 36" SS iroks and steel rims. I broke 2 axle shafts in the d35. I dropped it down to 35" nitto trepadors and aluminum rims and cut 75lbs out. I since have not had any issues with anything and the performance is much better. I also have a ford 8.8 that I am building to put in place of the d35.

Now on the other side of the table....I have also heard that locking the D30 may actually be better vs not locking. Reason being that a non locked front axle has to work harder to get over a certain obstacle. Which results in more stress which obviously results in more breakage.
