Bilstein bil51-353087 - B8 Pro Front Upper Control Arm Kit

B8 Pro Control Arms are a premium upgrade for factory upper control arms on trucks and SUVs with lifted suspensions. These heavy-duty black powder-coated 4130 chromoly steel tubular arms will correct the caster geometry on lifted suspensions for improved straight-line stability without the downsides of many aftermarket arms.  They feature an innovative low friction bushing design which provides a superior freedom of movement.  These new pivot bushings are maintenance free, long lasting, and will not squeak or require constant regreasing.  High strength sealed ball joints provide improved articulation over stock for maximum suspension travel and smooth steering feel. They come with detailed instructions, ball joint caps, and all necessary hardware for easy installation. B8 Pro Control Arms are the perfect complement to any Bilstein shocks or coilover kits and will improve your driving experience on or off the pavement. Tubular Ball Joint Upper Control Arm Kit
