Detailed Description

Delphi TC2566 is engineered as a rear suspension control arm for Mercedes-Benz vehicles that use the rear right upper rearward mounting location. Delphi applies OE-level dimensional and material analysis to help ensure the replacement arm matches the original part’s fit and function. The aluminum body and casting/forged construction support a direct replacement approach for suspension service on C-Class, E-Class, and CLS-Class applications.

This part cross-references MOOG Chassis Products RK641420 for the same application. It is also listed with interchange references including 102-7577 and K641420. Common fitment includes 2007-2015 Mercedes-Benz C-Class models, 2010-2017 Mercedes-Benz E-Class models, and 2012-2017 Mercedes-Benz CLS models in the rear right upper rearward position.

What It Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from the rear suspension area
• Uneven rear tire wear caused by worn control arm bushings
• Incorrect rear wheel alignment after suspension wear
• Restoring factory-style rear suspension geometry

Installation Notes and Tips

Verify the rear right upper rearward position before ordering, since this control arm is position-specific. Compare the original arm length, mounting points, and bushing layout to confirm match-up on your Mercedes-Benz C250, C300, C350, E350, CLS550, or related application. Because mounting hardware is not included, inspect existing fasteners and replace worn hardware as needed during service. A professional alignment is recommended after installation.

Quality Assurance

Delphi subjects steering and suspension components to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. That validation supports OE-style durability for everyday road use and long-term suspension service.
