The Upper A-Arms 73-87 Chevy C10 from UMI Performance are engineered for serious suspension builders and restoration enthusiasts looking to modernize their classic truck's front-end geometry. Built specifically for 1973–1987 Chevrolet C10 platforms, these upper control arms address the compliance and handling limitations of factory stamped-steel designs. Whether you're upgrading a street truck or preparing a show-quality build, quality upper A-arms are foundational to achieving proper wheel alignment, responsive steering feel, and reduced tire wear across the board.
UMI's upper A-arms are manufactured with precision-forged or cast construction that significantly improves stiffness and durability compared to original equipment designs. The arms feature reinforced pickup points and optimized ball-joint bosses that handle increased cornering loads and maintain consistent caster/camber angles under dynamic conditions. At 18 pounds, the assembly balances strength with unsprung weight consideration—critical for ride quality and suspension responsiveness. The geometry is designed to work seamlessly within the factory mounting locations while permitting modern alignment settings, making them compatible with both stock and lifted suspension configurations.
Mechanics and fabricators trust UMI upper A-arms for restorations that demand both authenticity and performance. Installation requires basic suspension knowledge—the arms bolt into existing factory mounts, though wheel alignment is mandatory post-installation to dial in proper geometry and ensure even tire contact. These arms are ideal for daily drivers seeking improved handling, restoration builders who want period-correct proportions with modern reliability, and performance builds incorporating lowering springs or custom ride-height adjustments. Proper installation with quality ball joints and tie-rod ends completes a professional front suspension transformation for any classic C10.
