Which suspension component is most important, the front lower control arms to adjust the caster or the front adjustable track-bar to re-center the axle.

I am under the understanding that the front lower control arms are most important because they should allow proper caster setting to be achieved which in turn helps control the Jeep to drive straight under high speed (freeway speeds) condition. Where as I believe the the front trac-bar is more of a cosmetic item to re-center the axle which might or might not prevent bump-steer.

I am to the point where I can buy one or the other but not both. Just trying to make sure I get the more important part of the two first.

FYI, I have the basic teraflex 3" kit on my 4dr. As it stands I believe the highway steering could be much improved.

Also I am eyeing the possibility of purchasing the Rough Country X-Flex front lower control arms, but I really haven't seen any posts of people with those yet, so has anybody got them yet?

 

You need both. Your tires and ball joints will thank you. After that save up for a front drive shaft. Get rear upper control arms to adjust pionon angle and this should save your rear ds. Cut and weld rear spring perches on axel to correct angle on springs [really improves ride on rough roads ] .

 

Take a look at Rusty's Lca's as well, mine have been great so far. I did the track bar first, and drove for over a year before I got the control arms.

 

I would do the LCA's now and the track bar as soon as you can afford it. I have both on my TF 3" and it rides very well on the freeway.

 

I would get the track bar first.

If you don't adjust your Caster correctly your JK will feel drifty (like it can't hold a straight line) and it a bit unstable. If you get a warn joint or bushing incorrect Caster angle can help trigger (not cause) DW like unbalanced tires.

You are complaining about your highway steering, so I think your choice is obvious.

The front adjustable LCAs are support large loads thats why the stock ones are beefy. The bushings and joints in the CAs are a critical component. I would go with aa brand of CAs that has better components like TF to match your lift. Avoid building a Frankelift as much as possible.

 

Get both for sure, but get the Front LCA's first they made a big difference on the road for me.
