Rubicon, how many inches before I need new driveshaft?

Jeffery · 07-05-2005, 09:58 AM

Ive got an 05 and considering a lift kit. I want to run some 33's on 17's. I dont have any plans on wheeling it, but still want it to flex and be somewhat functional. I was thinking about the RE 3.5" standard kit, will I be required to get a new shaft? I really do not see myself installing the transfer case drop if I put this on, it hangs too low as it is........

you'll most likely need a CV driveshaft in the rear after you go over 3". the front is fine.

You know the price difference for 15" and 17" wheel tires is quite a lot. The difference, for me, between 35x12.50x15 and 35x12.50x17 is so much I can't bring myself to consider the 17" wheels any longer. It's close to $100/tire. That's just not worth it unless I was running 37's or bigger.

3" or 4" if you have a MML or a 1" tcase drop.

Read my sig. I have the RE 3.5" kit and a MML and no vibes.

And you may want to go see just how much travel your driveshaft has remaining on the splined joint. With a 5" lift and the factory driveshaft, don't be the least bit surprised if/when your driveshaft is pulled off and falls to the ground when your suspension is flexed on the trail.

Jeffery, is your Jeep a "Rubicon" ???

Based on my experience, 2.5" is about the limit with the stock Rubi DS and an MML. You could go further with a t-case drop. You'll need adj. control arms to correct the pinion angle and a trackbar relocator (or adj. trackbar) to recenter the axle and make it drive properly again.

Mine is a 4" lift w/1" TC drop and with front end disconnected, I have not pulled my driveshaft apart either. This is with 2 yrs. of nonstop 'wheeling!
