Control Arms – Front – Black – Pirate Jack – 1969-1972 Pontiac Grand Prix

This part fits 1969-1972 Pontiac Grand Prix vehicles.

Upgrade your front suspension with Pirate Jack tubular lower control arms—built to add strength, improve handling response, and deliver a cleaner stance with a factory-style bolt-on fit. Lower control arms carry major suspension loads, so upgrading from worn factory components to a stronger tubular design can make a noticeable difference in front-end stability, steering feel, and overall road control.

These lower control arms are made from high-quality 1.625 in. O.D. x .156 in. wall DOM steel tubing, CNC bent and welded to factory fitment specifications for consistent installation and dependable performance. Each arm is finished in a durable black powdercoat for corrosion resistance and a clean performance appearance.

The stronger tubular construction helps reduce unwanted flex during braking, cornering, and quick transitions, giving your suspension a more planted and predictable feel. Included ball joints provide dependable service life, while Delrin bushings help isolate road noise and reduce deflection for smoother operation and sharper response compared to worn factory bushings.

A key feature of these lower control arms is the deeper spring pocket, which lowers ride height approximately 1.5–2.0 inches compared to stock arms. This gives your vehicle a more aggressive stance while improving road feel. This lower control arm setup also includes sway bar end links and bushings, helping support a more complete front suspension upgrade and improved handling performance.

These lower control arms work with factory springs and shocks, lowering springs, or coilover conversions, making them a flexible foundation for street, performance, and resto-mod builds.

Important Installation Note: Lower control arms feature 5/16” welded nuts at the lower shock mount points. These welded nuts must be removed or reamed out to 3/8” for Aldan American coilover t-bar installation. Modified parts are non-returnable.
