Bilstein Upper Control Arm Kit for Lifted Trucks SUVs

The Bilstein B8 Upper Control Arm Kit is a direct-fit upgrade for factory upper control arms on lifted trucks and SUVs. These upper control arms (UCAs) correct suspension geometry after a lift. They restore caster alignment for better straight-line stability and improve ball joint pivot angles for more wheel travel.

Key Features:

• Corrected caster alignment: CAD-designed geometry helps keep alignment within specification on lifted front suspensions.
• More wheel travel: Improved pivot angles reduce stress and binding on the ball joints and add travel over the stock arms.
• 4130 chromoly construction: Tubular steel arms are professionally MIG-welded with formed steel bushing gussets. They are stronger than stock arms and leave more clearance for springs and shocks.
• Black powder-coated finish: Helps resist corrosion.
• Low-maintenance joints: Greasable bushings and heavy-duty sealed ball joints balance ride quality and durability.
• Serviceable design: The arms are owner rebuildable.
• Designed to work with Bilstein lift shocks and coilovers: They pair well with Bilstein 5100, 6100, 6112 and 8112 suspension systems.
• Made in the USA
