Quiet a rattling stabilizer bar and keep your Mercedes' rear suspension tied together with the Delphi Suspension Stabilizer Bar Link TC3721. This link installs in the rear left position and drops in as a direct-fit replacement for the 2015-2020 Mercedes-Benz C300, 2015 C400, 2020 C43 AMG, C63 AMG, C63 AMG S, CLS450, CLS53 AMG, E350, E450, GLC300, GLC350E and GLC43 AMG — see the Buyer's Guide tab for the full list and engine specifics.

A stabilizer bar link connects the sway bar to the suspension to limit body roll and keep the bar working; a worn one is a common source of clunks or knocking over bumps and looseness in the corners.

  • OE-level validation: built on Delphi's OE steering expertise, with parts that withstand temperatures below -40°C and above 120°C plus 720 hours of salt-spray exposure.
  • Ultrasonic molding: helps prevent future weld breakage.
  • Fatigue tested: designed to avoid premature failure.
  • Micron-tolerance machining: for durability and smooth joint operation.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

Extensive dimensional and material analysis targets close compatibility between the OE and aftermarket part.
