I think IHC doesnt have a QC when welding these controls arms have had a few issues,lower control arms rubbing on frame,alignment issues,had to cut tie rods,lower control arm rubbing on the spindle,,every time i say something they say oh we never had the issue ect ect or they just dont say anything ba k,will be trying WULF controls arms soon,they have better bushings and you can bolt on the breake line on the upper control arm,they say they use same premium ball joints as moog they just have a private label,, i know IHC dont use moog anymore last 2 kits i got are not moog
