Detailed Description

Delphi TC1751 is a rear upper forward control arm designed for Mercedes-Benz suspension service where accurate fit and stable alignment matter. The aluminum construction helps maintain strength while keeping the part consistent with OE-style suspension architecture, and the included bushings support proper mounting at the chassis and suspension connection points. This part number, TC1751, is a direct-fit replacement choice for vehicles including the Mercedes-Benz CL500, S430, and S500, along with other listed applications.

Delphi applies OE-level testing and material analysis to its aftermarket steering and suspension portfolio. That includes exposure to extreme temperature ranges and extended salt-spray testing to evaluate durability in demanding conditions. This makes Delphi TC1751 a practical option for restoring rear suspension control on Mercedes-Benz CL500, S350, S430, S500, S600, CL55 AMG, CL600, and S55 AMG models.

This part cross-references Mevotech Supreme CMS101180 for the same application.

What This Control Arm Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from worn suspension bushings
• Uneven tire wear caused by worn rear control arm components
• Alignment drift after suspension wear
• Restoration of rear upper forward suspension geometry

Installation Notes and Tips

Install in the rear upper forward position only. Verify the vehicle application against the listed fitment before installation, especially on Mercedes-Benz CL500, S430, and S500 models. Because mounting hardware is not included, inspect existing fasteners and related suspension components for wear before reassembly. A professional alignment is recommended after replacement to confirm correct suspension geometry.

Quality Assurance

Delphi uses OE-focused engineering, dimensional checks, and material analysis to support fit and function across its aftermarket suspension portfolio. The part is tested for temperature extremes and salt-spray exposure to help validate durability in real-world conditions.
