Bilstein B8 Pro upper control arms replace the factory front upper arms on lifted trucks, correcting caster geometry for better straight line stability and steering feel. The tubular arms are 4130 chromoly, MIG welded with reinforced gussets and finished in black powder coat, and they pivot on maintenance free, greaseless urethane bushings with a composite liner and a free spinning inner sleeve. A sealed, rebuildable 4140 steel ball joint with an induction hardened stud adds articulation over stock. The kit requires direct fit replacement shocks or coilovers, is not compatible with lift spacers, and needs wheels with 4.75 in backspacing or less.
