HD Rear Upper Control Arm Set 79-04 Mustang

The BBK Performance HD Rear Upper Control Arm Set 79-04 Mustang is a heavy-duty suspension component engineered for Ford Mustang models spanning 1979 through 2004. Designed for drivers who demand improved rear-end geometry and handling precision, this fabricated upper control arm kit addresses the factory trailing arm limitations inherent to classic and modern muscle cars. Whether you're upgrading a street machine, weekend track car, or daily driver, this component restores proper suspension alignment and reduces the bind common in OEM systems.

Constructed from steel and finished in a durable gray powder coat, the HD Rear Upper Control Arm Set maintains structural integrity under cornering loads and acceleration stress. The fabricated design allows for tighter tolerances compared to stamped factory arms, reducing deflection during hard driving and improving predictable axle location. The set weighs 8.86 pounds and spans 22.9 inches in overall length, fitting within the standard rear suspension envelope of second through fifth-generation Mustangs. This configuration supports both street and strip applications, offering measurable improvements in rear-end stability during acceleration, braking, and lateral cornering maneuvers.

Performance enthusiasts, restoration builders, and autocross competitors benefit most from this upgrade, as the improved control arm geometry directly reduces tire scrub and wheel hop during aggressive driving. Installation requires standard suspension work and basic hand tools; alignment verification is recommended post-installation to ensure optimal toe and camber settings. The kit is compatible with 1979–2004 Mustang rear suspensions and integrates seamlessly with factory bushings and mounting points. For drivers seeking measurable suspension refinement without fabrication or welding, this BBK Performance solution delivers proven handling gains backed by decades of domestic performance motorsports heritage.
