Delphi TC9380 Suspension Control Arm and Ball Joint Assembly - Front Lower Rearward

OE-Style Suspension Control Arm

Delphi TC9380 is a suspension control arm and ball joint assembly for the front lower rearward position. It is built for Mercedes-Benz C300, C43 AMG, and C63 AMG S E Performance applications with fitment that spans multiple model years.

Key Features

• OE-focused design for direct replacement use.
• Front lower rearward suspension control arm and ball joint assembly.
• Engineered with dimensional and material analysis for OE-to-aftermarket compatibility.
• Tested for temperature extremes from below -40 C to over 120 C.
• Exposed to 720 hours of salt spray for corrosion resistance validation.

Detailed Description

Delphi TC9380 is a suspension control arm and ball joint assembly developed with Delphi OE expertise and applied to the aftermarket steering and suspension portfolio. The part is designed around OE performance expectations, with material and dimensional analysis used to match the original application as closely as possible. For Mercedes-Benz C300, Mercedes-Benz C43 AMG, and Mercedes-Benz C63 AMG S E Performance models, this control arm supports the front lower rearward suspension location and helps maintain proper suspension geometry.

This part cross-references Monroe Shocks & Struts (e.g., 2063304902, 2063305002) for the same application.

What It Helps Solve

• Excessive play or looseness in the suspension linkage.
• Noise from a worn ball joint or control arm bushing area.
• Uneven tire wear caused by suspension geometry issues.
• Steering response problems related to worn front suspension components.
• Alignment instability after suspension wear or replacement.

Installation Notes and Tips

Verify the front lower rearward position and confirm vehicle fitment by year, make, and model before installation. Because this is a suspension control arm and ball joint assembly, final alignment checks are recommended after replacement. Use the part number TC9380 to confirm application details during ordering and service.

Quality Assurance

Delphi applies OE-focused engineering and validation to this part, including extreme temperature testing and extended salt spray exposure. The TC9380 is built using dimensional and material analysis to support consistent fit and performance across the listed Mercedes-Benz applications.
