Delphi Suspension Control Arm P/N:TC2302
$80.99

Firm up your front suspension with the Delphi control arm TC2302, a front right upper control arm that locates the wheel and pivots the suspension through its travel while its integral ball stud lets the knuckle steer and articulate. It installs as a direct-fit replacement for the 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy, 2003-2006 Chevrolet SSR, 2004-2007 Buick Rainier, 2002-2006 Chevrolet Trailblazer EXT, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2003-2008 Isuzu Ascender, 2002-2004 Oldsmobile Bravada and 2005-2009 Saab 9-7X — see the Buyer's Guide tab for the full engine-level list.

  • Tested to OE performance: Delphi applies its OE expertise to the aftermarket, with parts that withstand temperatures below -40°C and over 120°C and 720 hours of salt spray; extensive dimensional and material analysis targets the best OE-to-aftermarket compatibility.
  • 100% inspected: Every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Robot-welded: Robotic welding delivers consistent quality and performance.
  • Precision ball studs: Ball studs are machined to micron tolerances for durability and smooth joint operation, and anti-corrosion protection is applied for corrosion prevention and enhanced appearance.

If a worn upper arm or its ball joint is behind clunking, loose steering or uneven tire wear, this replaces it. Order the matching side to keep alignment even.
