Just got new wheels and tires and I was worried that this might be a problem:

I currently have a 2.5 BB by Teraflex and wanted to know if the coil lift will be any higher than what I have.

 

Height won't really help as much as cutting your rock rails will be. There are a few threads regarding this very same issue and how to cut your rails as to not have your tires so close to them.

 

The coils will yield more lift, dylans right about trimming the rails/pinch seam. On an unlimited the coils will be about 3.1" front and 2.1" rear. Add .5-.75" on each if u have a 2 door.

 

If you do any offroading, you got some trimming to do, both pinch seam and sliders. Test your flex to check it out, on a rock, tree stump, anything, you'll see.

 

Did a writeup search, now I know what I need to do. Thanks for the help.

 

Test it by completely flexing the rear axles. If it does touch or get to close for your comfort you got two choices. Raise the body some way or triming.

It is the way it should be one mod leads to the next.

 

I'm learning this quickly.

There is also another dynamic. As you lift the rear the axle tends to move slightly forward. So for higher lifts the pinch seam gets closer to the tire in its static position, but as the suspension compresses it seems to compress up and slightly towards the rear.

 

Carefully trim and either hammer the pinchseam behind it (or trim it). I had to do the same to fit the 37s. I used black silicone and reattached the end caps.
