# QA1 67-70 Ford Mustang Street Performance Upper Control Arm Kit

Upgrade your classic Mustang’s front suspension with QA1’s tubular upper control arm kit. Designed for 1967–1970 Mustangs, this kit improves suspension geometry, enhances 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 alignment throughout suspension travel. The result is a Mustang that corners flatter and feels more planted in every driving situation. 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.
