Give your classic Mustang modern handling and durability with QA1’s tubular lower control arm kit. Built as a true bolt-in upgrade, these arms replace your factory components with stronger, lighter construction and optimized geometry. Perfect for street performance or restomod builds, QA1 lower arms are a must-have foundation for a more stable, predictable, and fun-to-drive Mustang. STRONGER DESIGN & IMPROVED GEOMETRY OEM arms simply weren’t designed for today’s performance needs. QA1’s tubular construction reduces flex, increases rigidity, and enhances suspension geometry. The result is improved cornering stability, more responsive steering, and the confidence that your suspension can handle modern power levels. EASY, BOLT-IN INSTALLATION Installation doesn’t get much easier. Each arm is a direct bolt-in upgrade for your factory arms - no cutting, no welding, no modifications required. With ball joints and bushings pre-installed, these arms come ready to bolt on and go.
