Restore proper caster geometry and straight-line stability to lifted trucks and SUVs with the Bilstein B8 Pro tubular ball joint upper control arm kit.

Designed as a premium replacement for factory upper control arms, this B8 Pro kit corrects suspension geometry for lifts without sacrificing ride quality or introducing the common downsides found in standard aftermarket parts.

Engineered for Performance and Durability

• Heavy-Duty 4130 Chromoly Steel: The tubular arms feature a black powder-coated finish that resists rust and corrosion, ensuring long-term durability in harsh off-road environments.
