track bar help

i have a 2.5" rubicon lift and now im going to a 4.5" lift and I was wondering if my rear track bar bracket off the 2.5" lift will work with the 4.5" one .. both are rubicon express.

I am pretty sure it will, I know other brands use the same bracket for different sizes

A flatter track bar angle will give you a better roll angle and better handling characteristics. Of you course you have to see what you can fit/clear, but one of these Track Bar Brackets may give you a better angle. Let me know what other questions you have or if you'd like a quote!

Welcome to the forum!

The majority of brackets that come with any lift kit are to correct the geometry as much as possible back to ideal conditions, since many of the critical angles are modified when you add the lift. The brackets that come with the 2.5" kit are designed for a 2.5" not a 4.5" so they will not correct the geometry completely and if the 4.5" came with any brackets it may actually make things worse.

Right

You want a axle side bracket that corrects roll center. Ideally slopped down from back to front.
Here's TF's version with multiple heights.

In a perfect condition (rear lift height and hole used match) the axle will be centered. More important ... Flatter/higher is better. Look at AEV/MC. MC sells the track bar and bracket together. AEV supplies a custom length non adjustable track bar. Both have bends to help clear the exhaust and set HIGH roll center in the rear. This is how you want it.
