Upper A Arm 9 Screw In

The U-B Machine Upper A Arm 9 Screw In (MPN 19-0908-5R) is a precision tubular control arm engineered for GM A-Body and G-Body platform suspension geometry. This 9-inch upper control arm features a screw-in ball joint design, 1-1/4-inch offset geometry, and heavy-duty steel construction with black powder coat finish for corrosion resistance. Single-piece tubular construction eliminates weak points common in stamped arms, delivering the structural rigidity required for both street and performance applications.

The screw-in ball joint design allows field service and replacement without specialized equipment, reducing downtime during maintenance or suspension adjustments. The 1-1/4-inch offset specification is critical for suspension geometry—this dimension directly affects caster angle, camber settings, and overall handling characteristics on A-Body and G-Body platforms. The black powder coat finish provides reliable rust inhibition in both dry climates and corrosive environments. At 3.62 lbs, the arm is engineered for weight-conscious builds without sacrificing strength. Steel composition ensures compatibility with factory mounting points and industry-standard suspension components.

This upper control arm is suited for Chevrolet A-Body (Chevelle, Malibu, El Camino) and G-Body (Monte Carlo, Regal, Cutlass) chassis requiring OEM-replacement or performance suspension geometry. Buyers performing suspension restoration, geometry correction, or performance handling upgrades will find this arm a direct fit for factory mounting locations. The screw-in joint design is preferred in competition and street applications where suspension adjustment and tuning are ongoing.
