Title says it. What do you all think are the most important things to first address when looking to upgrade a stock ZJ... Things that will have the best benefit for the least money.

KOR radiator support. I'm gonna get one soon.
new exhaust, Kolak can get you hooked up, or look for a dynomax/thrush. That's what i'm running. It's inexpensive, but does okay.
Receiver shackle bracket.

If at first you don't succeed, use more speed.

Must have?

Well that's easy.

Recovery points, rocker armor protection, skids, tires, and moderate lift. Add a cargo basket if you want to make the beast more useful.

What about upgrades more geared towards ON road performance and longevity? Air intake, fuel system, etc.??

I didn't realize the purpose of this forum was strictly to help people who only care about the off-road performance of their Jeep. Maybe I'm INSANE for thinking that since my Jeep spends 99% of its time on the road, I should maybe focus a little more on on-road performance first. A**holes.

This forum isn't solely for off-road performance, but it does tend to be mostly geared towards it. Just don't mention lowering it, or anything that kills the off-road ability, and people will help you out. It's definitely possible to make the Jeep a more useful and better road vehicle without losing its offroad ability.

Thank you comptiger. That's what I'm looking for. I have 30" At's and I will soon be getting a BB. So no, I'm not planning on taking away any off-road capabilities.

I think I read on kevinsoffroad that those don't really do anything. Is this the case?

i havent heard anything about them at all. but i would go with bigger tires. and maybe a cold air intake. then of course the rad support from kevins. thats being shipped to me now. next im looking at claytons kit. but cant afford it right now. i want 33s so bad now after seeing so many jeeps around here with them or bigger.

It depends what kind of handling/ride comfort you want. As a minimum this is what I'd do:

1) replace the control arm bushings, if the are original, they are toast by now. You can get the "clevite" solid rubber bushings from Kolak (vendor here). Or for less hassle maybe some aftermarket control arms.

2) Check all the steering linkages, replace with quality parts (Moog, TRW, MOPAR) as needed.

3) Replace the sway bar bushings.

4) Add a Hard-KOR steering brace.

These will get you back more or less to the stock handling

5) For better handling (but slightly harsher ride), get Up Country springs from a junkyard or someone on here. They do pop up from time to time in the classifieds.

6) Get new shocks. I'd recommend Monotube shocks. I went with Monroe Reflex Monotubes (not the regular Monroe Reflex, which are twin tubed). Quite popular but a bit pricier are the MX6 shocks. Your passenger won't need to use the "oh ****" handle when negotiating sharp turns. Nose dip under heavy braking is reduced as well.

7) Get a rear Addco sway bar with Energy Suspension frame bushings. Again less body roll.

And get an alignment.

This is for a stock, non heavily lifted vehicle (2" lift max). I'm sure someone will chime in if you want to go more extreme.

I'd definitely go for good shocks, and maybe slightly stiffer coils (OME maybe). While you may not feel you need the better handling, your passengers will thank you. My dad complains constantly that the 5.9 doesn't have anything to grab onto in turns He can't seem to understand that the door is good enough...
