Rock Krawler LCA's

I ordered a set of front lower control arms for my son's '04 LJ. He is running a 3" BDS lift with Bilsteins front and rear, with BFG 33x12.5-15 KM2's on Cragar Soft Eights. We are trying to eliminate a noticeable wheel shimmy, and slight pull to left. Have road force balanced wheels and tires, but not much improvement, and replaced steering linkage with the Crown HD set.

What length should we adjust the arms to? His last alignment got the tow-in to spec but caster was 3.6L/4.2R. So we are trying to improve caster and reduce wander. The front left LCA frame mount has minor trail damage and slightly bent from PO so this may be the issue as well.

I installed RK arms on my JK with OME HD lift and it definitely improved my wandering so hoping to accomplish the same on the LJ.

REGARDS

I installed my own Rock Krawler 5.5 long arm lift. At the same time I installed new Dana 44's. I measured like a mad man on every little detail. When it was all done I had major DW, drove it 10mph over to the alighnment shop, besides the few mistakes I made the castor was way off. I drove out of there at 60mph, the only time i get any wobble now is when my tire pressure is too low for street driving(8-11psi) or the hardware on all the linkage gets loose, especially the upper track bar mount.
Probably didnt help you too much, just my 2 cents.
