There's so much that goes into building one of these things properly. Also, rarely do you get away with only doing one modification. Most of the time changing one part involves a change of another for it to all work properly.
When I bought mine it was already on a crappy Procomp 4" lift. It was also re-geared with a SYE too. I slowly added Currie control arms, track bars, steering, etc. I did the Savvy under armor late last year and that meant I needed to relocate the lower shock mounts. Now the rear track bar rubs on the stock gas tank skid. So, I'm installing the Savvy GTS since it gives me more clearance.
It's never ending with these things!
