Ok! here we go!
I have RE 3.5 superflex, RE track Bar for 3.5 to 4.5 lift.
i have added +2'' rear shackles and i am going to add coil spacers from terraflex! I am on 33 12.50 15.
Will my track bar be ok for the coil spacers or do i have to change to a new one what lenght of bump stops will i need. What else do i have to look out for?

 

I'd suggest the following:

Is trackbar adjustable just add a track bar relocation bracket.

 

And that may cause Bump-Steer.....

 

how tall of spacers are you adding? as for bump stops you wont know until you go flex your jeep out and the measure

 

Or may not , and saves the wallet.

 

Ohhhh....

Why do it right when you can do it cheap?

Brilliant advise.

 

Ive never heard of any issues with them .

 

Serious is right, you need atleast a different Trac bar. Cheaping out on suspension is DANGEROUS! Do it right for your safety.
I have the RE 3.5 and will be adding the RE shackles n spacers. But my Trac bar is only rated for a 4.5". The RE kit actually gives you about 4-4.5 as is so we're maxed out on them.

 

The frame mount or axle mount ones?

 

Installing a track bar relocation bracket no way qualifies as cheap.

 

Basic steering geometry.
When the Trackbar and Drag link are not parallel bump-steer will likely result.

The greater the out of parallel condition, the more pronounce the bump-steer.

I've yank a bunch of those damn things.

 

Axle mount, id never extend a frame mount bracket on a unibody it would create to much leverage on it .

 

To each his own.

 

Correct. BUT. if you change the angle on the track bar and keep your stock steering. Then you might be creating an unparallel situation. You should decide what steering setup you want to run first. Then choose a track bar that will compliment that steering setup and angles. Just my thought process.
