Re-building my JK (Suspension)

[tae.h]

g'day!!!

07' JK 2dr Sport Automatic
Currently have OME 3.5" Lift with 33's, planning to go 35's soon.
Diff Ratio: 4.10 (D30 Front, D44 Rear)
ARB bull bar. That's it.
20% Offroad(Mild)
80% DD

I really want to correct my suspension set-up to make sure everything is alright to stabilize the vehicle as much as possible.
I guess the parts below will work a treat to my suspension set-up.

Ordered:
- LCAs (Teraflex)
- UCAs (Teraflex)
- Front Adjustable Trackbar (Solid Axel)
- Rear Trackbar Relocation Bracket (ARB)

Proper Front-end wheel alignment is a go, will be done with those new parts.

Wondering what else would I need?
LCAs and UCAs Adj. Trackbar will work a treat for now, BUT

What about other components like:
1. Driveshaft (to prevent the failure)
2. Drag link and Pitman Arm (don't really know what they are for )
3. C2 Gussets etc. (Reinforcement?)

Would I need those other components? Should be preferable though.
What need to be considered to be done to make the JK stable enough with other stock parts un-replaced?

Thank you for reading. Any inputs and advices are appreciated!!!
Let's fix the goddamn DW and make it right!

You are going down the right road with the Control Arms, however Lower's only would have sufficed.

Extended Swaybar Links shouldn't be overlooked, extended for the Rear and move the rear's to the front.

Technically, a High Steer Kit or something similar wouldn't be a bad idea to correct the Front End Steering Geometry, however with that level of lift I wouldn't be worrying about it too much, the Castor and Panhard should be sufficient.

Drive Train should be ok, however there are mixed stories on whether the D30 Front will handle 35's. Maybe just be gentle? Or go hard and break it and replace with D44.

Exactly
Thanks for your input TassieMav!

I found an opinion that the rear trackbar relocation bracket will eventually fail due to weak JK's factory mount.

Should I get a Rear Adj. Trackbar instead of the relocation bracket for a piece of mind?

I'd go the Adj trackbar if you can afford it. I have taken my Arb bracket off after seeing it put a sizable dent in the shock casing. I'm not sure when it happenend but at some point the wheel has had enough force exerted on it to squash the the bumpstop down far enough for it to collect the shock. Longer brakelines too either by way of a drop bracket or new braided ones are good idea.

Thanks dhard
So, Adj. track bars are the way to go for long run.
Also extended brake lines are now added to my shopping list, thanks to dhard!

Driveshaft problem with 3" of lift or more.

"IF you have an automatic with 3" of lift or more, with shocks long enough to give you greater flex and you wheel your jeep with the swaybar links disconnected as you should, your front drive shaft WILL make contact with your auto tranny and it WILL tear the spline shaft boot. there is NO exception to the rule here."

Still find it amusing that people call the OME 40mm (2") lift a specific 3.5" or 4" lift that they bought.

You have a good list going there and that will fix any issues that may spring up
