When is it necessary to get an adjustable track bar? Or how much lift can you do before you need one? Thanks

 

I would recommend getting one at anything over 2". I think you could get away without one on a 2.5 BB, but any spring Lift I would def say it would be a good option.

 

I saw a post where someone does the trigonometry and figures out how far off center your axle will be with different amounts of lift. Even at 2 inches you aren't going to be too far off center. Your steering and handling aren't going to be affected with an off center axle, so it's up to you if you want to get an Adjustable Track Bar or not from a axle position standpoint.

Looking at it from a strength standpoint is a little different. A coworker has 35's on his JKU and had a little wobble. He upgraded to a strong track bar and it fixed the wiggle. Having that track bar flex while underway can cause some negative handling characteristics.

Let me know if you have any questions or if you'd like a quote!

Thanks for info.

 

Hmm got a link to that?

 

I wish I could find it. I think it was over on JeepForum but I'm not sure. It was a few months ago at this point. I'll keep looking and post a link if I find it.

a squared + b squared=c squared
Where a is the length of your track bar
b is the amount of lift
c is the length the track bar needs to be after the lift at the factory mounting locations.
subtract a from c to get the amount of axle shift using the factory track bar.

Example for a 2" lift and 40" long track bar.

40*40 + 2*2 =c squared
1600+4=c squared
1604= c squared
40.049=c
c-a=.049


You can also use this to figure axle shift at droop.

at 2"of lift or droop you have .049" of axle shift.

At 4" of lift or droop you have .199" of axle shift.

at 6" of lift or droop you have .447" of axle shift.

At 8" of lift or droop you have .792" of shift.

At 10" of lift or droop you have 1.23" of shift.

You can use the same math to figure the amount of wheel base loss by using factory control arms with a lift.
The longer the links are, the less amount of shift will occure at different heights.

 

Is that info in your control arm link dirtman? It's common knowledge for you but not so much for everyone else. Thanks for what you bring to the table.

 

No, but I might add some of that information to it.

 

Sounds suspiciously like pythagoreans theorem to me...
