I have a 2.5 inch skyjacker BB lift already on my Jeep without the coils. What is the biggest size of teraflex coils I can get on my 4 door with manual transmission, before I would have to get new mods, other than the extended brake lines and shocks already installed...

 

If their lift is spacers, personally Id say dump the spacers & just go w/TF 2.5 coils. Otherwise if you dont want to do anything else to the Jeep, I wouldnt put any lifted coils w/spacers. The lift your at is the max Id feel comfortable telling someone to go w/out getting into modsville.

 

I have 2.5" Tf coils and that's the max I would go but you could probably go 3" I clear 37s with no rubbing with my 2.5" so I don't see any reason to go bigger until I upgrade to 60s.
