Keep the front suspension precisely located with the Delphi control arm TC2301, a front left upper replacement drawing on the OE expertise behind the safety technology Delphi fits to millions of vehicles worldwide. It fits many vehicles, among them the 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy and 2003-2006 Chevrolet SSR. This control arm locates the wheel and lets it travel up and down while maintaining suspension geometry, with the ball stud connecting to the steering knuckle.

  • Tested to the extreme: validated below -40°C and above 120°C and through 720 hours of salt spray for OE-level performance.
  • 100% inspected: crack detection and ultrasonic flaw detection confirm the materials match OE specifications.
  • Consistent build: robot welding for repeatable quality, plus ball studs machined to micron tolerances for durability and smooth joint operation.
  • Anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.

Worn control arms or ball joints can show up as clunking over bumps, loose or wandering steering, and uneven tire wear. If a failed front left upper control arm is the cause, this replaces it. See the Buyer's Guide tab for the full list of vehicles and engine-level details.
