Detailed Description

Delphi TC2301 is a suspension control arm designed for the front left upper position on vehicles such as the Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x. The stamped steel body and rubber bushings are selected to match OE-style suspension behavior, while Delphi’s dimensional and material analysis helps support proper fitment against the original part. This part cross-references MOOG Chassis Products (e.g., K200269) for the same application.

Common Suspension Issues Addressed

• Excessive front-end looseness or wandering
• Uneven tire wear caused by worn suspension geometry
• Clunking or knocking from worn upper control arm bushings
• Steering instability during braking or cornering
• Restoring alignment control after suspension wear

Installation Notes and Tips

Verify the front left upper position before installation and compare the original arm dimensions, including mounting-hole spacing and overall length, to confirm match. Because mounting hardware is not included, reuse or source the correct hardware as needed. A professional alignment is recommended after replacement to restore suspension settings.

Quality Assurance

Delphi subjects its steering and suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure, to evaluate durability and corrosion resistance. The TC2301 is built using OE-focused engineering practices for consistent aftermarket replacement performance.
