Delphi Suspension Control Arm P/N:TC3088
Delphi Suspension Control Arm P/N:TC3088
$55.99

Keep your Audi's rear suspension precisely located with the Delphi control arm TC3088, a direct-fit replacement for the rear right upper position on the 2002-2009 Audi A4, the 2002-2009 Audi A4 Quattro, the 2002 and 2004-2009 Audi S4, and the 2007-2008 Audi RS4. It carries Delphi's OE safety technology, built to withstand the temperatures and corrosion an aftermarket steering and suspension part faces.

  • Tested to the extreme: validated below -40°C and above 120°C, plus 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
  • Verified integrity: 100% crack detection and ultrasonic flaw detection help match OE material specifications.
  • Robot-welded: consistent welds for repeatable quality.
  • Micron-machined ball studs: support durability and smooth joint operation.

Anti-corrosion protection is applied to each part for corrosion prevention and enhanced appearance. As a suspension link, the control arm helps support and locate the wheel; signs it may need replacing include clunking on acceleration or over bumps, uneven tire wear, or a loose ball joint. Diagnose the cause before replacing.
