I currently have a 2.5" TF coil lift. I have added a 3/4" spacer on top of that. I know at some point I want to upgrade to 3.5"-4" springs. If I purchase adjustable f/r trackbars, and Front lower and rear upper adjustable control arms will I simply be able to drop the new coils in? I dont want to toss this kit and cant afford to just buy a new one but if I buy these pieces bit by bit will it yield same result? Most parts are saying "adjustable from 2.5" to 4" lifts" My front dropped about 2" just from bumper and winch. Im debating putting in 3.5" RC coils in place of the TF+3/4" spacers just to get it back up a bit. The coils seem to be stressed and both front shocks are leaking. Bumper and winch are heavy but I didnt think it would drop the front so much

 

I think you might need to replace driveshafts also with that much lift

 

Im not sure on driveshafts? Its an 08 unlimited with 6 speed

 

For a 2 door,you will need new front/rear drive shafts.For a 4 door a no upgraded drive shafts needed.
