Caster correction is right..

i have adjustable upper control arms with the stock lowers(fixed length). i'm still not happy with the way it handles. it seems like if i adjust the upper arm i'm not pulling the top of the axle back anymore. it seems like with non adjustable lowers i'm just pulling it back and not doing anything. do i need to go with adjustable lowers also or do i keep going with the uppers? last time i had it aligned the reading was 3.6 degrees on the left and 3.7 on the right. i shortened the arms a half turn and it did get a little better but i would like more caster. just thinking i may hafta add the lowers to get more?

Going in with the uppers increases caster. Add another 1° and that should help.

Are there adjustable uppers that adjust shorter than stock?

I ran just the MC front uppers for a year and a half after installing their lift and had it adjusted to about 4.3-4.5*. Now after bending and breaking my rear lowers I decided to get all 8 arms and be done with it.

I have the rubicon express adjustable uppers and they'll go shorter than the stock ones

Why would you go just uppers instead of just lowers on the front?

For caster it really does not matter. With the lowers you get the added strength as well as caster bump.

And also a larger selection since not all uppers adjust shorter than OEM.

Yep thats true
