Over the weekend with the help of a couple of forum members(jjvw and tworley) I outboarded my rear shocks and installed Fox 2.0 w/remote reservoirs. I purchased the shocks and had them tuned by pcoplin with fullstack motorsports. This is my initial review of the ride quality. A few details first, I am running 35x12.50x15 Goodyear MTR W/Kevlar at 25 psi on Raceline beadlocks. On the front end I am running Rancho RS55255 (5000x) shocks in 10.730 travel with Currie CE-9132FP 4" springs. I raised the upper shock mounts about 1-1/8" in order to achieve maximum uptravel. On the rear I am running the Fox shocks outboarded with a custom tune by pcoplin, and Currie CE-9131RH3P 4" springs. Both front and rear suspensions are set up at 50/50 travel bias with Metalcloak control arms at all 8 locations. This initial review involves about 50 miles this afternoon on the worst paved road I could find. The road is a two lane asphalt, with many corrugations, cracks, and potholes. It is traveled extensively by oil field traffic and farm equipment. With my prior bilstien shocks 55 mph was a serious adventure, jarring, hard bounces, potholes that would knock you out of your seat. I avoided the road at all costs. (Perfect for testing a new set up!)

The difference between the Bilstien and the Rancho on the front is significant. The difference with the Fox shocks on the rear is astronomical. I was able to cruise at 65mph, The tail of the jeep was planted, the Fox shocks just soak up the bumps like nothing is there. The side to side motion on the tail of the jeep is gone. It takes a pretty major pothole to feel the tail move, These shocks work! The custom tune is excellent so far. I can't wait for spring to get on some good trails so I can do a more thorough review.

Another comparison I would like to make is how different the front feels from the rear. With the Bilstiens bumps and potholes felt pretty similar front to back. Jarring, alot of body movement. With the Ranchos up front and the Fox shocks on the rear, there is now a large difference front to back, while I still feel alot of the smaller corrigations and smaller pot holes with the Ranchos, the Fox shocks really just soak them up.

Please keep in mind, I am no suspension expert and that these reviews are seat of the pants. I will post more reviews this spring and summer, as the trails here in Colorado up.
 
I drove Joshs a few weeks ago and the difference you describe between front ranchos and rear foxes is what I noticed too.

Bilstiens are a great shock for heavier applications (smooth as silk in my old 3/4 ton Dodge) but in TJs they are very harsh
 
The angle should be perpendicular to your lower control arms at ride height. Than you have to cycle the suspension, from full bump, to full drop, with and with out tires, see what hits, what fits, take your time, try and get as close to 50/50 travel as you can. Do a lot of research before you start!

I was really surprised at the difference, I didnt really have any expectations, as I hadn't driven a jeep with this set up. I was more so driven to do this mod initially based solely on the additional suspension travel, and the ability to gain the uptravel I had lost with the old rear Bilstiens

One of the local Jeep company guys told me they always use Fox because they’re rebuildable for a super good price and claim they ride better than tha Ranchos all around. I’m really tossing up a set of those VS the Ranchos everyone recommends when the time comes.
 
Awesome you were able to knock it out in a weekend! How did you go about raising the front towers 1-1/8”? Is there a reason you went with Rancho instead of Fox’s up front? I’m planning a very similar build with my LJ but I’ll be running Metalcloak 3.5” springs.
 
I raised the front towers by cutting them off about 1-1/2" from the top, than welding in a skirt the appropriate width to raise them the amount that I needed. I will get some pictures of what I did. I went with Ranchos up front for now because of budget reasons. I will eventually go to an 11 or 12" fox on the front as well. But you can get 2 Ranchos for 110$. For the Fox shocks it's the shocks, the towers, plus fabbing a lower mount on the front.

As far as one weekend, no. Saturday was about a 14 hr day, Sunday was another 6, Monday night 4 hours and finally last night was about 2 hours to finish up. That was with 4 guys working on Saturday
