Bring modern handling and durability to your classic Mustang with QA1’s tubular lower control arm kit. Designed 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, they tighten steering feel, improve stability, and stand up to today’s performance demands.

BETTER GEOMETRY & STRONGER DESIGN

Stock arms weren’t designed with modern performance in mind. QA1’s tubular construction reduces flex and improves suspension geometry, helping your Mustang corner flatter and maintain alignment under load. The result is sharper steering response and a more confident driving experience.
