Upper A Arm 8 Steel Screw In Ball Joint

The U-B Machine Upper A Arm 8 Steel Screw In Ball Joint (Model 19-0809-5R) is a precision suspension component engineered for GM A-Body and G-Body vehicles. This 8-inch tubular upper control arm features a screw-in ball joint design with a 1-1/4 inch offset, delivering the geometry and durability required for street performance, off-road recovery, and classic muscle car restoration. The black powder-coat finish provides corrosion resistance in demanding environments.

The 19-0809-5R upper control arm is constructed from steel and weighs 3.74 lbs. The screw-in ball joint design allows field replacement without special tooling, a significant advantage during maintenance or upgrades. The 1-1/4 inch offset geometry is critical for maintaining proper suspension geometry and ride height when modifying wheel offset or upgrading to larger tire packages. The 8-inch length is optimized for A-Body and G-Body platforms, ensuring correct geometry and suspension travel.

This component is essential for builders, restoration specialists, and performance enthusiasts working on first and second-generation F-body Camaros, Firebirds, Novas, and other GM A-Body platforms. It's particularly valuable when installing coilover systems, modern suspension upgrades, or correcting suspension geometry after engine swaps or chassis modifications. The screw-in ball joint format simplifies replacement intervals and allows upgrading to higher-quality aftermarket ball joints without replacing the entire arm.

U-B Machine is recognized in the suspension market for precision-manufactured tubular components that meet tight tolerances. When sourcing OEM or upgrade upper control arms for GM A-Body and G-Body builds, proper offset, length, and geometry specifications are non-negotiable—undersizing these details results in poor handling, uneven tire wear, and suspension binding.
