Detailed Description

Delphi TC3601 is engineered for the front left lower forward location on Audi A8 Quattro and Audi S8 models listed below. Delphi applies OE dimensional and material analysis to help maintain proper alignment, suspension response, and part-to-part compatibility. The aluminum body and forged/cast construction support a direct replacement approach for drivers servicing worn front suspension components on 2010-2018 Audi A8 Quattro and 2010-2018 Audi S8 applications shown in the fitment data.

This part cross-references 4H0 407 151 B and 4H0 407 151 C for the same application. If you are replacing a front left lower forward control arm on an Audi A8 Quattro or Audi S8, Delphi TC3601 provides the OE-style dimensions and mounting layout needed for a proper service replacement.

Installation Notes and Tips

Verify the front left lower forward position before installation and confirm vehicle notes, including the 2010 Audi A8 Quattro VIN break and standard vehicle option listings. Inspect adjacent suspension components, alignment settings, and mounting points during service. Mounting hardware is not included, and the ball joint is not included.

Quality Assurance

Delphi subjects OE-style steering and suspension components to temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. That validation supports consistent replacement quality for Audi suspension service.
