Adjusting the adjustable track bar

I just received my 2.5" leveling coils and my adjustable track bar from top gun customz. I noticed that on the adjustable track bar the only way that you can adjust it is to unbolt the "eye" on the threaded end so that you can either thread it in or out of the track bar depending on which way you need to adjust. This seems like it is going to be a MAJOR pain for the guys doing my alignment. What is everyone's thoughts? Has anyone had any problems with alignment shops complaining?

Why would they need to adjust your track bar on an alignment? You should be able to set the track bar to the right length and they will just do the toe and caster. Didn't it come with instructions on how long to make it to center the axle. Mine was just over 39 inches iirc.

No. It didn't come with any instructions. I figured it would need to be adjusted on the first alignment after the leveling kit was installed to get the axel centered back under the truck. And then it wouldn't need to be touched again unless the front end was lifted more.

So if I'm installing the 2.5" leveling springs what length should I adjust the track bar to?

Measure from a set point on the frame to another point on the axle before the lift. After you lift it, adjust the track bar so that the measurement is the same from stock. With the track bar disconnected, you should be able to turn the wheel and the frame will move a bit on the axle and get where you want to be.

Every truck will probably be different, so there isn't a set measurement.

I installed my tack bar not too long ago and ^^^^ is what Carli said to set it to for 3" of lift. I'm stock so I matched my stock bar which was about 38 3/4". This is a 3rd gen though, don't know if 4th's are different.

39 1/8" is what Thuren recommends you set the trackbar at for up to 3" of lift.

Well, my truck is up on my lift, but I have yet to have time to start tearing it apart, however i did just go take a rough measurment of the stock track bar as it is bolted to the truck and it looked to me like the stocker is right at 39" (center of bolt to center of bolt) but like I said it is a ROUGH measurment as it is still bolted up and I was having a little trouble making sure I was exactly center to center. But I figured you would have to adjust a little more than a 1/4" to a 1/2"... How bad out of center will the axel be with a 2.5" leveling kit and the stock track bar?

I'd just set it to 39-1/8" center to center, install it, and forget it.... Unless you change the lift height drastically.

Strait from carli, they told me 39 1/8" for my 2" front spacer, and the #'s are the same up to a 3" front lift, and I recall my stock length being 39" also.

If it is only 1/8" is there really a big need to change it? I thought it swings the axle way to one side the further you go up. I want Don's springs and just planning for the future.

Yeah what ^^^^^ he said. Is it really necessary then for 1/8" gain? How bad out will the axel be with the stock track bar?
