Upgrade your classic Mustang’s front suspension with QA1’s tubular control arm kit (P/N 52703). Designed for 1964-1966 Mustangs, this kit improves geometry, improves ride quality, and adds strength where factory components fall short. Perfect for street performance or restomod builds, purpose-built for use with QA1 coil-over systems delivering sharper handling, better stance, and more stability for modern driving. BETTER GEOMETRY, STRONGER DESIGN OEM arms weren’t built for today’s performance expectations. QA1’s tubular design increases caster for improved stability, tightens steering response, and maintains proper alignment through suspension travel. STRAIGHTFORWARD, BOLT-ON INSTALL Replaces factory components without cutting or welding and is also compatible with the popular “Shelby Drop”, including a drill template and nut plates. Fully assembled with hardware, they’re ready to bolt in and drive.
