Tighten up steering response and keep your Mercedes-Benz suspension properly located with the Delphi control arm TC3281. This rear upper forward control arm drops in as a direct-fit replacement for a wide range of Mercedes SUVs and crossovers, including the 2006-2013 R350, the 2007-2012 GL450, and the 2006-2011 ML350 — see the Buyer's Guide tab for the full 15-vehicle list and engine details.
Built on Delphi's OE safety technology fitted to millions of vehicles worldwide, this arm is tested to the extreme for OE-level performance:
- OE-matched validation: withstands temperatures below -40°C and above 120°C, endures 720 hours of salt spray, and is dimensionally and materially analyzed for close OE-to-aftermarket compatibility.
- Inspected to OE specs: 100% crack detection plus ultrasonic flaw detection confirms the material matches OE specifications.
- Consistent build: robot welding delivers repeatable quality across every part.
- Precision ball studs: studs machined to micron tolerances for durability and smooth joint operation, with anti-corrosion protection applied for corrosion prevention and enhanced appearance.
If a worn control arm is the cause of clunking, uneven tire wear, or loose handling, this Delphi unit replaces it. Sold individually; replace both sides together where applicable for balanced suspension.
