Old Man Emu is pleased to release Front Upper Control Arms for a range of popular 4wds. When an IFS vehicle is fitted with a suspension lift, the original caster and camber results can be pushed outside the factory adjustment settings. IFS vehicles generally have a few degrees of adjustment in their camber and caster from factory, adding an OME upper control arm brings the alignment cams back into an acceptable range for both caster and camber adjustment.
