Thanks in advance.
I installed only the front HD Old Man Emu springs and extended Billstein shocks, so now it's obvious I need to do the same in the rear. I've noticed that the 2" OME lift kit comes with 2 front coil trim spacers and 1 track bar extension bracket.
Where and what is this track bar and do I really need to install the front coil trim spacers? I got the front springs and shocks installed using brute strength and ignorance, but I'd like to avoid repeating it if it's not necessary.

The Jeep is a 12 Sahara. 4 door.

 

not sure about the trim spaces for the front coils. My questions are the trim spaces or bump stop extensions. When I did my 3 inch Plush ride coils I had to install bump stop extensions to keep from bottoming out the shocks. As for the track bar bracket, yes I would install it because it will recenter your axle and keep you from crabbing down the road. It is not that noticeable with 2 inches of lift but if you measure the exposed tread on the passenger side versus the drivers you will see a difference. The track bar bracket will make them match.

 

Track bar bracket goes in the rear, TB front.
My guess is the trim spacers even out the common JK lean ?

 

I did not need to use the front coil spacers with my OME HD springs. They can be used if you find that you have rake that you don't like. My jeep with heavy front bumper and rear bumper/tire carrier sits level without them. Your setup will determine if you need them. Since the front is already done I'd install the rear springs and see how it looks to you.

 

That is what I was hoping, thank you all.
