Detroit Speed Engineering Suspension Control Arm

Detroit Speed Engineering Suspension Control Arms: Precision Engineering for Classic Muscle

When it comes to transforming the suspension geometry of a classic GM muscle car or truck into something that handles with modern confidence, few names carry more weight than Detroit Speed Engineering. Their tubular suspension control arms represent one of the most focused and thoroughly engineered product lines in the pro-touring aftermarket — designed not just to replace worn factory components, but to fundamentally improve how a vehicle corners, tracks, and communicates with the driver.

What Sets Detroit Speed Control Arms Apart

For nearly three decades, Detroit Speed has operated a world-class build shop that crafts award-winning vehicles, giving the brand invaluable insight into the real-world challenges of building modern-day restomods. That hands-on experience flows directly into their control arm designs. Parts are made using state-of-the-art manufacturing technologies — CNC machining, forging, hydroforming, and more — to bring classic muscle cars into the 21st century.

Detroit Speed's tubular upper control arms are a showcase of this philosophy. The arms feature CNC machined tube ends for precision fits, are TIG welded in a fixture for accuracy and repeatability of geometry, and have a ball joint pocket CNC machined from billet for increased strength. Rather than relying on generic rubber bushings, the arms utilize Detroit Speed-designed greaseable aluminum/Delrin™ bushings with increased stiffness over stock, providing more consistent and precise handling. Each kit also includes two sets of "Caster Tuner Bushings" so builders can dial in caster without shims or guesswork. The arms are powder coated gloss black and come assembled with ball joints — ready to install out of the box.

Vehicle Coverage: Built for Iconic GM Platforms

Detroit Speed's control arm catalog is laser-focused on the classic GM platforms that define American performance history. Upper control arm kits are available as bolt-on enhancements for 1967–69 F-Body Camaros/Firebirds and 1968–74 X-Body Novas, as well as the 1970–81 F-Body Camaro, Firebird, and Trans Am. GM A-Body, G-Body, and compact truck applications round out the lineup, ensuring wide coverage across the golden era of Detroit iron.

For builds requiring a more integrated approach, Detroit Speed also offers an exclusive control arm and spindle kit designed to work as an integrated system — the taller spindle provides 2 inches of drop from stock height and improves handling by modifying the camber curve, resulting in negative camber gain during suspension compression. The A-Body tubular upper control arms in this system provide increased strength and additional positive caster, featuring five-axis laser cut tube ends and ball joint pockets for a precise fit.

American-Made Quality, Backed by a Real Warranty

Detroit Speed products are designed by their team of engineers and are produced in the USA using the latest manufacturing practices. Detroit Speed warrants that the products will be free from defects in material and workmanship for two years from the date of sale to the original purchaser — a meaningful assurance for a component as critical as a control arm. Whether you're building a dedicated track car or a pro-touring street machine, these arms deliver the geometry, strength, and finish quality that serious builds demand.
