I recently bought a jku with the 4 inch Rancho trail system lift. It had 315/70/17 (35in) micky thompsons on it. I ran the stock tires shortly after I got it for the winter. Just put the 35s back on and its definitely a way rougher ride. Not sure if its do to the road conditions we get in New England during the winter or suspention/steering components. It went decent with the stock tire setup. A little bumpy but tolerable. I added rear extended sway bar links when I got it to make the sway bar and rear track bar parralel. I have been reading that the front draglink and track bar must be the same. I have taking a couple of pictures to show the angle of them and looking for any input. I just have to figure out how to post them on here

Here are a few pics of my front end

Drag link flip and get a raised track bar bracket. That would help considerably to get everything parallel . Castor / pinion ? Do you have adjustable control arms or geo correction braces..?

Well that Trackbar has a weird bend in it so it's hard to judge. However, looking at the last photo it appears that both the track bar and pitman arm start at the same point and the lower ends also end at the same level so I would not say that is the problem. Inspect all your end joints on Trackbars and control arms for worn out sloppy parts.

Thank you for the input. I will check for sloppy parts however I dont hear any weird noises or anything. The lower control arms were replaced with the lift but not adjustable. Track bars are stock. Rear has a drop bracket on it

Is that bend in the track bar not supposed to be there? The Jeep had a minor front-end Collision before I got it and some components were replaced I was told. Does anybody have pictures of what the proper geometry should look like on a 4 inch lifted JK? Thanks

Not that this is 4" but you get the idea. My track bar has a kick in it but not nearly that extreme Metalcloak track bar here and it's at 2.5".

Take the bends out of the equation.

Snap a single pic that shows both ends of both bars -- in the same pic. Open it in Paint or whatever, then draw straight lines from mounting point to mounting point. Easy to see just how parallel they are.

A flip will raise the axle end of both of these bars, keeping them parallel to each other, while flattening the angle they work at. (or in the case of a drop pitman, lower both bars from the frame end)

That track bar doesn't look stock to me. Drag link is stock looking though. Either way with that much lift you should have a raised track bar bracket on the axle and flipped drag link setup. I would have the 35's balanced to . 32 psi is a decent air pressure for a good ride but that's subjective to the individual.

That is certainly not a factory Trackbar. It has an adjuster/ pinch bolt at the top end.
It appears that it may also have a drop pitman arm.
