Keep the front suspension geometry tight and the ride controlled with the DELPHI control arm and ball joint assembly, MPN TC9127. This is the front right upper unit, and it drops in as a direct-fit replacement on many vehicles, among them the 2012-2013 Mercedes-Benz CLS550, the 2012-2013 Mercedes-Benz E300 and the 2010-2013 Mercedes-Benz E350 — see the Buyer's Guide tab for the full list. Delphi applies its OE expertise to this aftermarket part, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket component.

  • 100% inspected: each control arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Micron-tolerance ball stud: the ball stud is machined to micron tolerances for durable, smooth joint operation.
  • Robot welded: welded by robot for consistent quality across every part.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

Delphi tests to the extreme for OE performance — parts withstand temperatures below -40 degrees C and over 120 degrees C and are exposed to 720 hours of salt spray. If a worn upper control arm or ball joint is the cause of clunking, wander, or uneven tire wear, this assembly replaces it.
