I have a 2004 rubicon with a 4 inch fabtech lift and a 1 inch body lift, there are other things including a t case drop and a motor mount lift I believe but it was all done by the PO. So one of my rear shocks busted the upper bar pin. I removed the shock and am awaiting a pair of RC upper bar pin eliminator kits. I got to thinking, I bought the rig with all of the lift and such attached. It's old and has definitely seen some use off and on road (105k miles worth). I might start invest in upgraded (not necessarily the best shocks/springs/ control arms but I will spend money for quality) suspension parts to refresh the system as a whole. I like the way it's setup now height wise so my question would be for general advise of to dos and not to dos. What shocks should I look at? Springs? I don't have the money to invest in a complete terra flex kit but I'd like to upgrade piece by piece. Suggestions comments and concerns welcome! Thanks for looking

Personally, if it were mine, i would start with some good quality adjustable control arms (currie or metalcloak), then a double cardan rear drive shaft and get rid of the t-case drop. Replace the shocks if needed; Rancho rs5000x are getting great reviews. Don't know what you have as far as track bars go, but that would be something to look at. Springs would be the last thing you would need to worry about.

if you are going piece at a time, make sure you go premium. Like parts Water Dog suggested. Spend hours and hours here and on other forums to really learn what is working for others.

Do it right the first time you spend the money or you will regret it later.

I just started a 03 tj build.
I am going with the RS5000x shocks and a Savvy 4" all aluminum control arm lift.
Will be doing SYE and DC driveshaft at the same time.

Just pulled my front driveshaft and going to go through that too. Buying all new spicer joints for it. Figured it needed some attention after 117k miles. Everything is stock on mine right now.

Check out the rest of the Jeep too. I need to order a new Mopar radiator. Mine is a leaking just a little.
I also am doing the valve cover gasket since it has a slight leak.

Make sure your frame is in good shape and you are taking steps to prevent rust.

The lift on it currently has non adjustable control arms. Would you suggest upper and lower?

IMO, any 4" suspension would benefit from 8 adjustable control arms. They will not only allow you to adjust your rear pinion angle for the double cardan drive shaft (that will allow you to get rid of the t-case drop), but they will also allow you to position your axle (front & back). The adjustable fronts allow adjustments to front pinion angle and caster. Adjustable track bars will keep your axles centered right to left.

I run 8 currie adjustable arms on my 4" suspension lift, and it drives down the highway better than stock. although a little pricey, after experiencing the difference in the way the Jeep handles, it would be my first upgrade on another one.

Im liking the Rancho RS5000x! I am having trouble finding the correct part numbers though. If i have a 4 in lift and 1in Body lift which part numbers should I be looking for?

I confirmed these part numbers with member "Rancho" here.

I bought them from Allen's off road.
Ordered last Friday (18th) and received yesterday (24th).

Still waiting on my lift.

Ordered 15x8" 1069 procomps with 33x12.5x15 GY duratracs on the 23rd.
Starting to get excited for it all to come in.

Good luck on your Jeep.

Alan

UPDATE

So far I have upgraded only the shocks to the rs500x's, but i am about to order the 8 currie adjustable control arms from savvy off road (i hear there is a WF discount but have yet to find the mysterious code) I have a ? regarding the rear drive shaft. I plan on dumping a shiny penny into Betsy here with the control arms and I would like to raise my clearance with an under body aluminum skid plate (Not sure which one yet) but will doing this change the length of my rear driveshaft? I don't know if i can do it all at once because poor college kid and I would HATE to buy a fresh TW driveshaft and then a year later an aluminum skid and need a new driveshaft...

OH and I'm doing all this in prep for a cross country drive to moab in the spring. too pumped.
