Special Notes
Modern Geometry for Real-World Performance
Factory upper control arms were never designed for today’s tires, speeds, or driving expectations. QA1’s tubular design rethinks the geometry from the ground up—increasing caster, improving camber control, and keeping alignment stable throughout suspension travel.
The result?
-
Flatter cornering
-
More confident high-speed stability
-
Faster steering response
-
A Mustang that feels planted instead of floaty
This is the upgrade that makes your classic Mustang feel tight, predictable, and ready for modern roads.
Stronger, Lighter, and Built to Last
Constructed from high-strength tubular steel, these upper control arms are lighter and stronger than stock stamped units. Each arm is finished with a durable powder coat to resist corrosion and road wear, ensuring long-term reliability whether your Mustang lives on the street or sees spirited weekend driving.
Pre-installed ball joints and bushings mean everything is assembled and ready to go—no guesswork, no extra trips for parts.

FREQUENTLY ASKED QUESTIONS (FAQs)
What advantages do QA1 tubular upper control arms offer for 1964–1966 Mustangs?
QA1’s tubular upper control arms are designed to correct factory suspension geometry by adding caster and reducing unwanted flex. This results in better straight-line stability, quicker steering response, and a more confident feel during cornering compared to the original stamped steel arms.
Will these QA1 upper control arms work with stock spindles?
Yes. The control arms are engineered to be fully compatible with the original factory spindles and aftermarket Proforged spindles used on 1967–1970 Mustangs.
Is fabrication or welding required during installation?
No fabrication is necessary. These upper control arms are a direct bolt-on replacement and come pre-assembled with ball joints, bushings, and all required mounting hardware for a straightforward installation.
Can these control arms be used with coilover suspension systems?
Yes, they are specifically designed to be used with QA1 Pro Coil coilover systems. They will integrate seamlessly with an existing QA1 coilover setup and are not intended for use with factory shocks and springs.
Where should I begin when upgrading the suspension on a classic Mustang?
A solid starting point is upgrading the control arms, followed by coilovers and sway bars. Control arms provide immediate improvements by strengthening the suspension and optimizing alignment, which enhances handling before moving on to additional components.
How do these upper control arms affect overall handling and driving feel?
By increasing caster and maintaining more consistent alignment through suspension movement, these control arms help the Mustang track straighter, corner flatter, and feel more responsive and stable—especially during aggressive driving or spirited street use.
