Keep body roll in check and preserve a planted, composed ride with the Delphi Rear Suspension Stabilizer Bar Link Kit TC1781. This sway bar link kit connects the rear stabilizer bar to the suspension, transferring load between the wheels to limit lean through corners and over uneven pavement. It's a direct-fit rear replacement for the 2005-2011 Audi A6 Quattro, the 2006-2011 Audi A6, and the 2007-2011 Audi S6 — see the Buyer's Guide tab for full engine-level fitment.

  • OE-derived engineering: built on Delphi's OE steering and suspension expertise, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket part.
  • Validated durability: tested below -40°C and above 120°C and exposed to 720 hours of salt spray; sway bar links are fatigue tested to help avoid failure.
  • Ultrasonic molding: links are manufactured with ultrasonic molding to help prevent future weld breakage.
  • Precision & protection: machined to micron tolerances for smooth joint operation, with anti-corrosion protection applied to each part.

Worn links often show up as clunking or rattling from the rear over bumps and looser handling in turns — signs these may need replacing.
