I put on the teraflex 2.5 coil lift with Bilstein 5100s...and also left 1 inch spacers front and rear....so its easily 3.5 plus inches higher.
I have front LCAs and Adj track bar coming in today to correct casster and axel shift in the front.

My question is on the rear....is the drive shaft at to much of and angle? ( what is to much? ) and I also noticed my springs have a slight bend to them The pics make it look worse than what it actually is.
So take a look and let me know what parts are needed to correct the springs or if they even need corrected. And if you have any idea on the drive shaft....any info there would be helpful as well.
Just to note...jeep rides great and I have no complaints. Just want to be on top of things and sure I am doing everything right.

the bow in your rear springs is totally normal but, if you want to straighten them out, i would recommend installing a set of jks adjustable rear spring perches. as far as your rear drive shaft goes, the cv boots will be in a constant state of pinch and will fail sooner than later - trust me, it happens all the time. when it starts to fail, you will see grease spitting out from the boot area and sticking on the bottom of your tub and along the gas tank. let it go too long and you will start to hear a ratcheting sound which will be the bearing going bad - this is when you're done. an aftermarket 1310 shaft like the kind that coast makes is what i would recommend to address the problem. you will need adjustable rear upper control arms to set your pinion angle too.

 

Perfect...thats exactly what I needed to know. Guess I need to put in another order with Northridge4x4!

When you say sooner than later on the drive shafts...we talking days, weeks, months?
Also, what should the pinion angle be on the new shaft? Is there a DIY on the install of it somewhere?

 

There are quite a few how-to's down in the write-ups area.

And you could spend a few minutes browsing the Tech Info area on Tom Woods website. Regardless of which shaft you choose, there is some good stuff there, including these diagrams of the angles you want with both stock shafts and aftermarket double cardans.

(the rear uppers suggested by WOL are used to point the pinion up as in this pic. And note that the spring perches he recommended would be very usefull here also.)

 

Thanks!! great info to get me started on the right path!

 

You may want to consider either spring perch wedges or the adjustable spring perches if your coils bow too much. When you add the upper control arms and rotate your pinion up to set your pinion angle it will make the bowing worse. I'd imagine that this is worse on a 2 door than a 4 door because of the shorter wheel base. You could get lower control arms also, then you can set your rear axle back further but again the bow of the rear springs may definately contact your rear trac bar.
I have a 4 door w/ a 4.5" lift and adjustable control arms. My rear axle is centered in the wheel well so it is set back about an inch or so, but when the pinion angle was corrected for my rear driveshaft, my spring bowed and contacted my rear trac bar on the passenger side. I put in Rough country correction wedges and it fixed the contact problem, minimized my bowing but it is still there.
