Tighten up your vehicle's handling and quiet those front-end rattles with the Delphi Suspension Stabilizer Bar Link TC2509. This front sway bar link connects the stabilizer bar to the suspension, helping control body roll and keep the wheels working together through turns and over bumps. It's a direct-fit replacement for the 2004-2008 Pontiac Grand Prix, 2005-2009 Chevrolet Uplander, 2005-2007 Buick Terraza, 2005-2009 Pontiac Montana, 2005-2007 Saturn Relay, and 2008-2009 Buick Allure and LaCrosse — see the Buyer's Guide tab for engine-level details.
Delphi applies its OE engineering to the aftermarket, validating parts across extreme conditions — below -40°C, over 120°C, and 720 hours of salt-spray exposure — with dimensional and material analysis for close OE-to-aftermarket compatibility.

This part cross-references / interchanges with the following part numbers:
What does this stabilizer bar link do?
It links the front stabilizer (sway) bar to the suspension, helping control body roll and keep the front wheels working together through turns and over bumps.
What are signs my front sway bar link may need replacing?
Clunking or rattling from the front over bumps, knocking during cornering, and looser-feeling handling are common signs. Diagnose the cause before replacing, as other parts can produce similar noises.
Does the Delphi TC2509 fit my vehicle?
It's a direct-fit front link for applications like the 2004-2008 Pontiac Grand Prix, 2005-2009 Chevrolet Uplander, and 2008-2009 Buick LaCrosse. See the Buyer's Guide tab for the full list.
Should I replace both sway bar links at once?
They're sold individually. Since both sides wear at a similar rate, many technicians replace the left and right links together for balanced handling.
How is this link built to last?
Delphi uses ultrasonic molding to help prevent weld breakage, fatigue testing to help avoid failure, micron-tolerance machining for smooth joint operation, and anti-corrosion protection on each part.
