Product Overview

QA1's Mustang street control arms are the perfect combination of performance and style, offering lightweight, durable construction and a clean, sleek design that will enhance the look of your Mustang.

Forged Ball Joint Housings

A unique feature of the QA1 control arm is the forged ball joint housing. This provides exceptional reliability, strength, and durability. The low-friction ball joint ensures smooth operation, and the rebuildable, lightweight, and greaseable design makes maintenance a breeze.

Polyurethane Bushings

Compared to factory-installed rubber bushings, polyurethane bushings are stiffer and more resistant to deflection, providing enhanced stability and control. They also allow for freer movement, resulting in a more responsive ride. Additionally, greasable polyurethane bushings are much more durable than rubber, making them highly resistant to wear and tear.

Lightweight Design

QA1 street control arms were designed to be the strongest, best looking control arms on the market.  And weighing less than 9lbs per arm, this makes them among the lightest control arms available.

Easy, Bolt-In Installation

Our commitment to thoughtful product design is evident in every product we produce, to deliver the highest level of performance, while ensuring trouble-free compatibility.

Made in the USA

QA1 control arms are proudly made in Lakeville, Minnesota.
