QA1 67-70 Ford Mustang Street Performance Lower Control Arm Kit

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.

Upgrade the suspension performance of your classic Mustang with the QA1 QAP52704 tubular lower control arm kit. Designed as a true bolt-in replacement, this kit replaces the factory lower control arms with stronger, lighter components engineered for improved rigidity, suspension geometry, and driving response. It is an excellent foundation for street performance, handling upgrades, and restomod builds requiring more predictable cornering and durable suspension performance.
QA1 tubular construction helps reduce flex compared with conventional stamped-steel factory arms, allowing the suspension to respond more consistently during cornering, braking, and acceleration. Optimized geometry improves steering response and stability, while the one-piece design eliminates the need for a separate strut rod. Ball joints and bushings are pre-installed, helping simplify installation and reducing the time required to prepare the components before fitting them to the vehicle.
This QA1 QAP52704 kit fits 1967-1970 Ford Mustangs and requires no cutting, welding, or fabrication. The arms are compatible with factory and Proforged spindles. They replace the separate strut rod and work exclusively with the QA1 52803 sway bar; they are not compatible with OEM or other aftermarket strut rods or sway bars. Finished with a durable black powder coating, the kit is built for long-term service and is sold as a pair. Professional installation is recommended, and suspension components should be inspected and properly aligned after installation.
