Question Help! 3.5" Lift or 4"?

I have a 2 1/2" Rubicon Express Lift and 33" BFG KM2's and i have maxed out what i can do on the trails im riding now. I want to be able to run 37's in the future and at this point just want to buy a new lift to run 35's and then 37's and change gearing later on. I have looked at many lifts and i am torn between the rubicon express 3.5" lift and superlift 4" lift. Now my question is, Both of these lifts come with:

* Front and Rear Coil Springs
* Front and Rear Compression Stops
* Front Track Bar
* Rear Track Bar Bracket
* Front and Rear Brake Hose Relocation Brackets
* Cam Bolt Assembly
* Rear Sway Bar End Links
* Front and Rear Shock Absorbers

-I have asked some tech's and have read some articles on lifts like this and i am wondering if i need to replace my driveshafts? If i do not should i look into adjustable upper and lower control arms to right the angle of my cv joints? HELP!

Chop your flares, add more bumpstop, and slap the new tires on now...



* Cam Bolt Assembly
Seriously?

There isnt a cam bolt set that i can find for an 07 JK. All i want to know is if i need to replace driveshafts on my 2door JK when i lift again or can i correct the driveshaft angles with adjustable arms

Correct with arms, I wouldn't trust the bolts.

as mentioned, DO NOT install cam bolts, use adjustable lower control arms to set your caster. as far as drive shafts go, yes, you will need to replace your rear shaft and will need a set of adjustable upper rear arms to do that. if you have an auto, you will need to replace your front shaft as well.

Adjustable arms are a much, much better choice.

As far as driveshafts go, you have a 2door auto, correct? Pretty much the worst model for keeping stock shafts. Plan on replacing both! You will need front lower and rear upper arms to set the angles on the new shafts.

Neither of those lifts would make my short list. Just an opinion, but you might keep looking. If you are set on those two, you should consider not installing the cams and getting adj ca's with the lift, rather than waiting for the driveshafts. (and note that both companies make 'fixed' ca's, so be sure you are getting adjustables.)

Ok thanks for the clerification and yes i do have a 2007 JK 2 door automatic. I am going to hold off and look into more lifts with arms and just purchase driveshafts as well in the future. I am just anxious

Sir

I know this did not make your list, but check our our Rock Krawler 3.5" X Factor Mid Arm System. To us, this is one of the best price pointed and functional systems for fitting 37's under a mild lift. By pushing the rear axle back 1" we have made fitting 37's a snap. You could easily run 35's now with full fenders and when the time is right, jump to 37's with either the right bump stops, by nicely cutting the OEM plastic fenders or going to a flat fender of some sort. Here is a link to it.

If you have any questions, let us know and good luck with your build. Keep in mind all of our products are upgrade-able. In the future you could jump to a long arm or even coil overs. It is up to you.. Like we said, good luck with your build...
