What is the advantage of just installing lower control arms and using the stock uppers? 2.5" lift front 3.5 lift rear. Also going to change out the trackbars front and rear...

Which order is best to do the work? Control Arms then Trackbar (im guessing this is the correct order).

General rule is the center the axles first, track bar but it also depends on how the Jeep drives. if you have wandering issues, better to address that with controls arms then the track bars next.

Advantage to control arms is getting the correct alignment specs, caster specifically. You can go into the type fo joint you buy and the advantages of those but with lowers only the uppers will limit the articulation gain you'll get from lower control arms

In previous Jeep models, a trackbar would've been my first recommendation, but with JL's they seem to be handling their track at 2.5" without issues, but having really bad caster issues at anything above 2".

If funds are short, I'd recommend starting with Front Lowers. If you have a little extra, add the track bar. Then if you have some extra, do rear uppers.

The Front lowers help to correct caster as stated above, but the uppers in the rear are really the ones that help to correct pinion angle for the rear axle. It is recommended that if you are doing 4 arms versus 8 arms, its best to start with Front Lowers and Rear Uppers.

So track bars first, then control arms?

The control arms are the skyjacker control arms for the 1 to 4 kit..

I would recommend getting adjustable control arms instead of fixed. The skyjackers look like they are fixed arms. I could be mistaken, hard to tell from the picture. With the adjustable ones you’ll be able to dial in your castor to what works best for your rig. Just a suggestion.

Adjustable control arms in terms of importance. 1) Front lowers to set caster 2) Rear upper to set pinion 3) rear lower to dial in axle location 4) front uppers for the same.

at your minimal lift, front lowers and call it a day. maybe rear uppers as well if you just want to dial in everything.

check out Core 4x4 adjustable arms at great pricing. Clayton's overland+ arms are great value as well.
