Newb.. Lift Questions

Hello all!

I plan on doing a lot of reading the next few days. And i would prob be flammed for posting this without using the search. But im sorta in a hurry to get things rolling.

Own an 06 Wrangler Unlimited 6Speed. Currently its my Daily driver, but next summer good chance she will be shipped over sea's.

So as for the questions go!

Lift Kit
Been looking into the 4.5-Inch Super-Flex suspension system by Rubicon Express. Would really love to run 35x12.50's but from what im hearing and reading 35's as far as DD use go aren't the best option. But if i were to go this route, what kind of other upgrades will need to be done besides the usual SYE and CV Driveshaft? Would 35x12.50s fit on OEM 15x7 wheels? Will they rub? Would i need an additional 1" BL?

IF i were to go with the 33x12.50s what would be needed?

Any input/advice would be greatly appreciated. Any info or suggestions on other products would also be greatly appreciated. Im new to the 4x4 scene. Always been in the car scene and bike scene... FIgured its time for something new lol.

Thanks!

the 4.5 in lift would clear the 35s fine, but you would need to re-gear it and would problly want rims with less backspacing or wheel spacers, that would give it a nicer stance. there shouldn't be a need for that body lift but if you have the cash go for it a 1in body lift is a nice size for body lift, 33s wouldn't need that big a lift if you want to go a lil cheaper as for other products get rocker guards and dont buy nerf bars

Thank you for the response!

I am currently reading up on the whole "re-gearing" issue. Correct me if im wrong, but from what im seeing i currently have a Dana 35 3.73.1 ratio (4.0L 6Speed Man)... What in gods name is needed to re-gear lol? I see kits online for D35s at 4.88, ect at around 200$... Yet im reading and seeing prices around 1300-1600. Am i missing something or the majority of the cash is going towards labor? Also, for a daily driver what ratio would be ideal? I would like both decent road and off road performance keeping MPG in mind. Currently im at 16mpg (I have a heavy foot) and now worried that will drop drastically 80+ on the E-way. I dont mind 65-70 with decent millage with both on road and off road performance.

Again, any suggestion would be great!

Thanks again.

You're going to want to regear the axles to 4.88 if I remember correctly. You'll need a set for the front and rest, and the master install kits to go with them. Much of the cost is the labor as it takes time, and must be very precise. My gears and install kits were ~$600 and the labor was ~$600 as well so I was $1200 put the door.

So i have a D35 in the front, and in the rear? Or is the front different? On the website i dont see anything that states D35 Front, only one i see that says Front-Rear is (Rubicon). Would installing a locker when re-gearing be a wise choice? I would like to install one locker in the front. I honestly never figured this would be such a headache lol. I was shooting for a certain budget and i already surpassed that haha... Crap.

If you go with a 35" tire there are going to need new rims, steering box will need upgraded, brakes need upgraded, steering tie rod needs upgraded. You also need new gears 4.88's and at least a super 35 kit for the rearend, but should go with a ford 8.8, or a dana 44!

So the D35 for the rear wont cut it? Even with re-gearing? Where could i locate a Super 35 and D44 kit? As far as steering goes, do you mean a stabilizer or a heavy duty steering kit?

Also, what about the Front D30? Im assuming this would need to be re-geared as well. And would the front need an upgrade kit as far as axles and diff go?

Would all this be needed to run 33x12.50's? Wheels im already leaning towards new ones.

Thank you!

Yes you will need a couple upgrades. You really should change rims, steering tie rod, gears, and a super 35 kit for the rear minimum!

You will need gears front and rear and new front axle shafts would be wise. Superior axle makes both the super 35 kit for the rear and the upgraded front shafts as well.

Thanks again for the help. Have started the "Parts list". Will post soon for feedback/advice. Hoping to pull the trigger by Monday or Tuesday. As far as wheels go, what type of back spacing am i looking for? The wheels im looking at are 4.75 back spacing. Would this clear 35s?

And some more questions. What would the re-gearing + both rear and front lockers install run me (labor only)? Wheels/tires i can have mounted for free and hopefully free alignment.. Lift kits/ Tie rod kit/ Steering Kit will be installed by my old man an me (Should be interesting lol).

Also! Diff locks. Would both rear and front be over kill? I plan on doing more upgrades later down the road (Snorkel/Winch/bumpers ect..). I was originally plannin front only, but since ill be doin the re-gear i was tossing around the idea of throwing in a rear diff lock.

IIRC, with a 12.5 inch wide rear tire, you need 4-3.75" BS, labor for geer and traction aid install will vary depending on where you are, what kind of deal you can find, etc. most on here seem to be paying around $1000.

Would the 4.75 backspacing give me a wider look (more poke)? Or is it the opposite? The same wheels they have in a 3.75 back spacing option as well.

the 4.57 would tuck the tires under the jeep more then the 3.75

im running 33x12.50's on 15x10 w/ 3.75 back spacing. i've got D44's w/ 4:10's. they stick out past my fender flares about 3" or so. but i did notice a change when i went from 31's to 33's, before it was alot easier at lower rpm's!

Looks nice! I was looking at similar wheels. But my jeeps white with Grey top and fenders, so the black look im still undecided. Might go polished.

With 4:10's installed it was sluggish in the lower RPM? Do people normally go with the 4.88 on 35's for the D44?

yes. those gears are there to compensate for larger then stock tires. they would be the recommended set up no matter what axle you had(except the d35, that would just be worthless due to how week the axle is).

Don't rush. Do more research and get it all done right, my 2 cents. You'll need gear change, steering upgrade, brake upgrade, proper lift and bumpstop, D35s stock can't handle 35s offroad, drive train upgrades, control arms, trackbar changes...and a fat wallet. Just went down that road. If you are not doing anything extreme, build for 33x10.5s, be happy and save $$
