Control Arm Kit Front Lower 78-88 GM G-Body

The QA1 Control Arm Kit Front Lower for GM G-Body models 1978–1988 is a professional-grade tubular suspension component engineered for pro-touring applications and performance upgrades on classic GM platforms. This lower control arm kit delivers the geometry and rigidity needed for chassis control during aggressive driving, street performance, or autocross competition where factory suspension geometry falls short.

Constructed from steel with a black powder-coat finish, the kit provides corrosion resistance and durability in both street and track environments. The tubular design maintains structural integrity while optimizing weight distribution compared to stamped-steel OEM arms. This control arm assembly is designed as a matched pair, ensuring balanced front-end geometry across both sides of the suspension. The 30.2-pound weight and compact envelope (20.5 × 17 × 21.5 inches) make installation straightforward on second-generation G-Body platforms including the Chevrolet Malibu, Monte Carlo, and Pontiac Grand Prix.

Buyers upgrading G-Body suspension for road-course driving, show car builds, or long-term reliability benefit from QA1's focus on geometry precision and material consistency. This kit addresses the compliance and wear inherent in decades-old factory control arms, restoring response and predictability to the front suspension. Fitment covers the full G-Body generation span, making it compatible with Chevrolet and Pontiac mid-size models across the 1978–1988 production window.
