1:1 jeep tj questions
 

I wanted to post this on pirate4x4.com, but it wont let me. i figure there has to be some 1:1 wheelers here that can help me.

I am soon getting a jeep 00-06 TJ and I am going to upgrade so that I can take it to the trails. I wanted to research as much as I could on the subject so that I would not get any unanticipated expenses. I plan on running

37 inch tires (haven't decided on which tire yet).
AEV highline body kit http://www.aev-conversions.com/products/highline/
rocky road skid plates http://www.rocky-road.com/jeeparmor.html
heavy duty axles http://www.rocky-road.com/jeepaxle.html

I want a 2.5 inch ome suspension lift, and a 1 inch body lift. Their web site is missing some info. scroll to the bottom of the page to the complete ome lift kits, it doesn't say what size lift, would it be a 4" lift, or what. which one would I choose? http://www.rocky-road.com/jeepome.html

what if I were to just get the springs and shocks in the section just above, would i need new track bars?

will I need a new steering damper for the larger tires/ a new steering system to turn the larger tires.

with the larger tires i'll also need to gear it down. Im going to go with the 4.88 reduction. Do I need the rebuild kit and the carrier, or just the gears. I assume I will need two of the kits, one for each axle.

I will need new brakes to control the 37’s, I don’t know where to get new brakes/ if the jeep full disk conversion is enough to stop with 37’s. With a 2 inch suspension lift and a 1 inch body lift, will i need new brake lines?


I’ll also need to recalibrate my speedometer, how/ where do I go to get this done?

can anyone think of something i will need that i have not thought of.

Those "heavy duty" axles wont handle 37's. Hell, they'd do well to keep up with 33's. 488's will not be enough gear for those tires (depending on the engine). I have 488s with 33's and wish I could go lower.

As for better brakes, look into the VancoPBS big brake kit.

Yes, you will want a better steering system. That pump and box wont like those tires.

Also, I wouldnt order from RR....they have made a bad name for themselves....

what are some websites that I should order from?
Do I need a completely new axle to run 37's?
can I make a jeep like this for around 10k? or will everything that I will need to run 37's jack that price up.
btw all service to equip the upgrades will be free.
what are the best companies to go with for skid plates, steering, tires, and all jeep stuff?
I plan on getting a stock jeep TJ from 2000-2006 in good condition and make it like the pic's below.

Sifting through all the information and choices on the net makes this task almost impossible. Every time I think im on the right track I learn something that shoots it all down, lol.

If you don't beat on it real hard 37 will work however you are pushing it like said befor you will want deeper gears or you will move like a slug. I have 36" swampers running on my d30 cromoed and 8.8 with 4.88 gears on a 4 cy it would be nice to have deeper gears but I am limited to those with the D30. Just don't beat on it too hard or it will go boom!

Well, what do you want to order? I always get good service from Dave at Northridge4x4.

If you are looking at heavy 37's then your front axle will also need a lot of work.

Warn makes full floater kits for the rear and hub conversion kits for the front along with stouter axle shafts, I still wouldn't go above a 35" with factory axles. Sure it might be allright, but I wouldnt go with it'll be allright as long as I don't get on it too hard.
Check out www.4wd.com
Been around for a long time.

I'd like to order everything that I need to run 37's, but i dont know everything that I need to run 37's.

What is the cheapest axle that i can use 37's on and still able to go nuts on them. btw, I want to keep this street legal, it'll be my daily driver and trail rig.
if I get new axles do I still use the stock links, or do I replace those too? will a dana 44 work, would it be ok to buy such items from ebay, or should i really get them new.

It really sounds like you need to buy the jeep and wheel it stock for a while. In the meantime, read up on what it takes to run those tires, so you dont waste money on the wrong stuff. If you want to "go nuts" with those tires, then you will need strong axles. Neither your front or rear stock axles will be up for the task.
Yes, you will need to replace the crappy stock control arms.

Yeah, just drive it stock for awhile and read, research, and figure out exactly what you want, based on solid research, not just what some guy on a forum says. Besides, axles, tires and other upgrades your easily talking 10K +.

If you wheel anything hard enought you will break stuff just look at the people on Pirate who blow up there D60's being stupid but they always have a heck of story to tell on how they broke there junk "thumbsup"

First off, buy the Jeep if ya want it, but going from stock to massive is a big jump and will change everything. How much experience do you have in an off-road vehicle? Do some more reading, and Pirate4x4 isn't really the place for newbies, they tend to flame ya pretty bad. Check out WranglerForum.com - its a really social place with some nice people(me being one - AzTJ).


37 inch tires (haven't decided on which tire yet). - Not many to choose from but my fav are IROK's or the new BFG KM2

AEV highline body kit - A waist of money. Get some tube fenders for the front and Gen-Right extended corners for the rear.

rocky road skid plates - Never heard of RockyRoad, but armor should be number 1 priority on your list.

heavy duty axles - For 37" Tires, your looking at Dana60's or better, with 5.13 gears or deeper.

It seems like you want to keep a low COG, but if you want that along with 37" tires, a wheelbase stretch would be best.. and then it gets expensive, but seeing as how your looking into new axles... :roll: Do you really have the time and money to dump into this without and wheel time? There are a lot of other options out there, especially if your goal is 37" tires. Do some more research, it will save you loads of time and money.

after reading what all of you have to say i think i'll get an already done up jeep and mod it later. i have a budget of around 10k and was hoping to get a jeep with a good chassis, body and powerplant, and make it like the jeep i gave the links to earlier. Realizing now that i will need new axles/links/steering/brakes/brake lines it will be really expensive. i've found a jeep with a 6 inch long arm lift, winch, 35's tube fenders, and more for 9.5k. i think i will get that one, and lower it about 2.5 inches.

That sounds like a better plan...

I always heard, never buy a lifted jeep, all your buying is someone elses headache. Although that was with CJ's, maybe it dosnt apply to TJ's.

Control arms and coil spring are a lot more complicated. :-(

Sadly enough, I still think he's going about this the wrong way. Even though it already has all this work done to it, most of it will have be torn off if his goal has 37" tires. Still need better axles, gears, tires, control arms, coil/coil-overs. Either way you look at it, its going to cost money. ;-)

This jeep im looking at has 35's. i'll wait a while before i put 37's on a jeep if i have to upgrade EVERYTHING. i was hoping i could get the jeep in the links i gave before for 10k but since i cant i'll buy one thats done up, and wheel it as is.

btw, i'd still like to make a list on everything that i would need to make a durable 37inch tire jeep, just so i know exactly how much it would cost.

would a dana 44 in the front and a dana 60 in the rear work for the tires, or dana 60's f/r? what companies make tj links for dana 44 & 60 axles?

im probably going to kick myself for giving the link to this jeep and get more potential buyers on it but i'd like to see what you guys think of the jeep i may get.it has 35's but i don't see anywhere about better axles.

Why are you so hell bent on getting 37's on a 94 inch wheel base Jeep? 35's are plenty for any trail in this country. What do you really think you are going to gain with the 37's, other than an inch under the diffs?
If you really plan to jump to 37's I would make the first modification on the wheel base. Bump that to around 100 inches.
As for strenth, you can run 37's with a front Dana 44, especially if you run a Super Kit on it, etc.
The 44 is a super strong axle. Don't doubt its stoutness.
Of course, 60's just buy you that extra strength but I don't feel it is totally necessary. Also, you keep saying that you are going to "go crazy" with the Jeep. You don't sound like you have any real experience with 1:1 off roading and you intend to hit the trails and to just go nuts from day one?

My advice is to be happy and run 35's. They are a huge tire and will get you over anything most of the time.

this will show you what it will look like with different combos

Thanks for all the help guys.

I wanted it to be durable and get the right axles so that i only spend the money once. I'd rather spend more upfront and only pay it once, than have it break, repair, break, then upgrade. But seeing what you guys have said I will stick with a smaller set of tires.

btw, I use to be a test vehicle operator for NATC, only quit because of college, no recreational offroading though.

remember.....even with Dana 60's and 35's, you can break stuff. You say you plan to "go crazy". You'll break no matter what you have. If not the axles, you'll break other stuff too.
