You have both front and rear track bars. They keep the axles centered under the Jeep. TJ's do not have leaf springs to help with that.

Front runs from driver's side frame to passenger side of axle. Rear is the opposite.

The track bar is an important & necessary part of your Jeeps suspension. It provides a connection between the axle housing & the frame to keep the axle centered under the body. Your Jeep also has a rear track bar for the same reason.

Not sure why you felt so compelled to provide the forum with those two points.....but DUH.

Along with keeping the axle laterally constrained, the front track bar provides the leverage necessary to turn the tires. Without it, the frame will just shift sideways over the axle but the tires won't turn. Additionally, the track bar defines the roll center height which describes how the front end will respond when cornering.

AKA--if you don't have leafs, it's absolutely critical.

Because 95% of the owners will never need more than a few inches of suspension travel so the conflicting arcs of the track bar, drag link and leaf springs will never realistically come into play. Plus, it gives the steering box something to directly push against. The difference isn't large, but the steering is a bit less direct on leaf-sprung rigs without a track bar.

Actually it doesnt limit travel enough to matter, and it does make them drive better. Historically there are alot of vehicle with trackbars and leafs.

Too add to that IIRC my 2000 Ranger didn't have a track bar in the rear nor do the Silverado's and Sierras. Actually now that I think about it a lot of trucks with leafs in the rear don't come with track bars.

He's talking front. I've never seen a vehicle with rear leafs and a track bar. Absolutely pointless redundancy and they'd be fighting each other constantly.

I guess I should've said "aside from a YJ". I still don't understand why that was the case.
