Upper A Arm 8 Steel Ball Joint Plate Style

The U-B Machine Upper A Arm 8 Steel Ball Joint Plate Style (part number 15-0804) is a precision-engineered control arm designed for vehicles requiring heavy-duty suspension geometry. This tubular upper control arm features an 8-inch length with a bolt-in ball joint configuration, delivering the rigid performance demanded in high-stress driving conditions where suspension reliability directly impacts vehicle handling and durability. The steel construction with black powder coat finish resists corrosion while maintaining structural integrity under repeated load cycles.

At 3.59 lbs, this control arm strikes a balance between strength and weight efficiency. The ball joint plate design allows for straightforward installation and field adjustment, critical for users who need to fine-tune suspension geometry or perform maintenance without proprietary equipment. The black powder coat provides corrosion resistance suitable for multiple climates—essential for vehicles exposed to salt spray, mud, or continuous outdoor deployment. The universal fitment designation indicates broad compatibility across suspension platforms, though application-specific validation is recommended before installation.

This control arm is engineered for operators, fabricators, and vehicle builders who demand OEM-grade components for custom suspensions, off-road platforms, or performance restoration work. The 8-inch tubular geometry is optimized for vehicles requiring intermediate arm length—neither compact crossovers nor full-size trucks, but rather mid-size vehicles needing precise suspension kinematics. The bolt-in ball joint construction simplifies serviceability compared to welded joints, allowing field replacement without structural rework. The U-B Machine pedigree signals manufacturing consistency and dimensional accuracy critical to suspension assembly.
