Bilstein B8 Pro Tubular Upper Control Arm Kit – Restores Caster Geometry and Stabilizes Lifted Truck or SUV Front Ends

Replace compromised factory upper control assemblies with a structural upgrade engineered specifically for vehicles that have raised their ride height. This tubular arm design eliminates the flex and alignment drift common in stamped steel replacements, delivering consistent ground clearance and predictable handling dynamics.

• Constructed from heavy-gauge 4130 chromoly steel with a corrosion-resistant black powder coat to withstand severe impacts and environmental exposure on unpaved trails.
• Pre-installed low-friction pivot bushings eliminate chassis squeaks, remove routine lubrication maintenance, and deliver consistent steering feedback across wide operating temperatures.
• Equipped with fortified sealed ball joints that expand suspension articulation limits, correct negative caster shifts from lifting, and lock in predictable straight-line tracking.
• Designed for direct replacement at factory mounting points, measuring 18.25 inches in effective arm length with a packaged size of 15 by 8 inches and a total weight of 20 pounds.
• Compatible with standard and extended-travel lifted suspension architectures, providing reliable clearance and damping synergy for paired Bilstein shock or coilover installations.
• Ships with annotated assembly diagrams, protective ball joint sleeves, and complete fastener sets to streamline bench-to-vehicle transfer and guarantee proper torque sequencing.
