Delphi TC5379PX Front Upper Control Arm and Ball Joint Assembly

The Delphi TC5379PX is a front upper suspension control arm and ball joint assembly engineered to restore OE-level steering and handling performance. Built on Delphi's decades of original equipment expertise, this assembly is a direct-fit replacement designed to match factory specifications for a straightforward, no-hassle installation.

Key Features:

• OE-Grade Quality Control: Every control arm undergoes 100% crack detection and ultrasonic flaw detection to ensure materials meet or exceed OE specifications
• Robot Welding: Precision robotic welding on all assemblies ensures consistent structural integrity and performance
• Micron-Tolerance Ball Studs: Ball studs are machined to micron tolerances for smooth joint operation and long-term durability
• Corrosion Protection: Anti-corrosion coating applied to each part for enhanced longevity and appearance
• Extreme Temperature Tested: Validated to withstand temperatures below -40°C and above 120°C, and exposed to 720 hours of salt spray testing
• Integrated Ball Joint: Comes as a complete assembly — control arm and ball joint included, ready to install

Delphi's TC5379PX control arm assembly reflects the same engineering standards used in OE production, making it a trusted choice for restoring suspension performance and vehicle safety. The included ball joint eliminates the need for separate component sourcing, saving time during installation.
