Rear Upper Control Arm for 2003-2004 Mazda 6 - Delphi TC5612

Help restore proper ride control in your rear suspension with the Delphi control arm TC5612, a direct-fit replacement for the 2003-2004 Mazda 6. This rear upper suspension control arm locates the wheel and knuckle through the suspension's travel and, with its integrated ball stud, helps keep alignment geometry where it belongs.

• Built to OE-level standards: Delphi's tests take each part below -40°C, above 120°C, and through 720 hours of salt spray, with dimensional and material analysis targeting close OE-to-aftermarket compatibility.
• Verified integrity: 100% crack detection and ultrasonic flaw detection confirm the material matches OE specifications.
• Robot welding: used for consistent, repeatable joint quality.
• Precision ball studs: machined to micron tolerances for durable, smooth joint operation, plus anti-corrosion protection applied to each part.

If a worn rear upper control arm or its ball stud is behind clunking over bumps, uneven rear tire wear, or a loose feel, this Delphi control arm replaces it. If you're searching for a 2003 Mazda 6 control arm, this one is cataloged for the rear upper position; see the "Vehicles it fits" section for full application details.
