I have a 2.5 coil and shock lift presently, but have noticed with the addition of my bumper and winch the front sit somewhat lower again than the back. If I install the 1" Teraflex coil spacers, will this change the geometry of my drive shafts where I begin to have issues?
Right now, everything is great, and no problems whatsoever.

 

I just put these on my Unlimited with a RC 2.5" coil lift. I had the same front end drop with the winch/bumper combo, but these spacers got it back to a good level stance. No problems with them.

 

I had the stock coils with TF 2.5 BB spacers and when I installed my bumper and winch, my jeep nearly sat on the bumpstops. I installed 3" Teraflex HD coils and now I'm perfectly level. I still have the spacers and stock springs in the rear.

 

I had the cil spacers originally that was 2.5 in the front and 2 in the rear. I also added a bumper and winch to the front so i got some heavier rate springs for the front. I ordered 2.5" springs by OME and they came from 4x4northridge. I kept the 2" spacers in the rear. I am sitting back level now.

 

they also have a 3/4" spacer you can look at to help with the sag. Did you measure before and after the lift? how much did you loose with the added wieght?
