QA1 64-66 Ford Mustang Street Performance Upper Control Arm Kit

If you're working on a 1964-1966 Ford Mustang and looking to seriously improve its front-end performance, QA1's tubular upper control arm kit is a solid choice. These aren't just replacements for your old, tired factory arms; they're a significant upgrade designed to bring your classic Mustang's handling into the modern era. They address the limitations of the original design, offering increased strength and better geometry for a more stable, responsive ride, especially when paired with performance suspension setups like QA1's own coil-overs.

The real benefit here comes from the improved geometry. By increasing caster, these arms help your Mustang track straighter on the highway, making steering feel tighter and more precise. This also contributes to better stability during cornering. The tubular construction is a smart move too – it's stronger than the stock stamped steel arms, and it's also lighter, which can make a small but notable difference in overall vehicle dynamics. QA1 pre-installs the ball joints and bushings, and includes hardware, making this a straightforward bolt-on installation that doesn't require cutting or welding. They even include a template and nut plates if you want to perform the popular “Shelby Drop” modification, further optimizing your suspension alignment.

This kit is sold as a pair, ready to install on either side of your Mustang's front end. The durable powder coat finish not only looks good but also helps protect the steel from the elements. If you're building a street performance car or a restomod and want a noticeable improvement in how your Mustang handles and sits, this QA1 kit is a well-built component that delivers on its promises.
