Delphi TC6784 Suspension Control Arm - Rear Right Upper Forward

OE-Style Rear Right Upper Forward Control Arm

Delphi TC6784 is a suspension control arm built for the rear right upper forward position on select BMW applications. It combines aluminum construction with a casting/forged design to support precise suspension geometry and consistent fitment.

Compatible with 2008-2013 BMW M3 and 2011 BMW 1 Series M, this Delphi control arm is engineered using OE dimensional and material analysis for strong part-to-part compatibility. Delphi TC6784 is a direct-fit suspension component for drivers replacing worn rear suspension hardware on BMW M3 and 1 Series M models.

• Aluminum construction for reduced weight and corrosion resistance
• Casting/forged design for structural strength
• Bushings included for service-ready installation
• Gray finish
• Straight shape with fixed, non-adjustable geometry
• Rear right upper forward position

Detailed Product Information

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, and TC6784 reflects that approach with careful dimensional and material analysis. The arm measures 240.5 in length and distance between mounting holes, with a width of 57.0 and height of 49.5, helping maintain the intended suspension layout on the rear right upper forward corner. This part number is a practical replacement choice for BMW M3 and BMW 1 Series M owners addressing rear suspension wear.

This part cross-references Beck/Arnley 102-7968 for the same application.

Common Problems This Part Can Address

• Excessive rear suspension play or looseness
• Clunking or knocking from the rear suspension area
• Uneven tire wear caused by worn control arm bushings
• Imprecise rear suspension alignment after component wear
• Restoring proper rear right upper forward suspension location on BMW M3 and 1 Series M models

Installation Notes and Tips

Verify the rear right upper forward position before ordering and compare the original arm dimensions to Delphi TC6784. Because mounting hardware is not included, reuse or source the correct hardware as needed. After installation, a professional wheel alignment is recommended to confirm suspension geometry.

Quality Assurance

Delphi tests suspension components across extreme temperature ranges and extended salt-spray exposure to evaluate durability and corrosion resistance. The brand’s OE background and material analysis help support consistent fitment for BMW suspension service.
