I have a 00 TJ that is somewhat of a Mutt but it works for me. I have to drive this Jeep on the highway a lot so this is not the set up I would be running if I was doing serious off roading/rock crawling. If that was the case, i would go with GenRights long arm. The majority of my off-road driving is over-landing with a trailer.
RK rear upper and lower arm
RK front upper arms
Rancho front lower arms
JKS 3" springs
Synergy x-over kit
Skyjacker front control arm geometry correction brackets
Rancho track bars with Synergy bracket
Fox ATS(JK Style) steering stabilizer
Metal Cloak sway bar brackets
Falcon 3.3 shocks(won them at Jeep event)
The Jeep started it's life with me as a Stolen recovery, no fenders, bumpers, wheels, or interior. But most importantly NO RUST on the frame and body. It does have a salvage title out of South Carolina though.
There was a lot of trial and error to get to this set-up. I will briefly tell you some of those and why I decided on what i did. I am by no means an authority on any of this but I am proud of how the Jeep rides.
I originally had all RK arms with Rancho springs and Rancho 9000's shocks. The ride was okay but not very comfortable and it had a nasty bump steer.
I swapped the lower arms with Rancho's new synthetic bushing hoping to get a little more comfort and added Skyjacker correction brackets. Clearance was not an issue for me as I am very deliberate of my line choice when off-roading because I am usually not with a group and have to be self sufficient. This def corrected the bump steer but I was still looking for a better ride.
The Rancho springs were linear so I decided to try RK multi rate springs but I was not able to get a set that kept the Jeep level. The first set had me doing a three inch wheelie, i swapped the front springs and the front was now two inches lower. I gave up on the RK springs and went back to the Rancho's for the time being. Another Jeeper suggested I try JKS TJ springs. So I picked up a set of 3" springs from JKS and these were just what i was looking for. Level ride with small bump compliance that firms up nicely. I was going to try Metal Cloak springs after the RK debacle but the gentleman on the phone at MC would not give me the time of day so I moved on. I have heard a lot of good things about them though. In contrast, RK was very accommodating even though we were not able to get the set up I wanted with their springs.
For the shocks, I am currently running Falcon 3.3 but honestly i do not feel any difference over the Rancho 9000's. Considering the Falcons are almost 4 times more expensive, I would stick with the Rancho's. But the Falcons do look cool.
The rest of my set-up is Used Core 44's Detroit in the Back and tru-trac in the front with 4:10's.
