Detailed Description
Delphi TC1625 is engineered for front upper suspension service where precise fit and consistent joint movement matter. Delphi applies OE-level dimensional and material analysis to its aftermarket steering and suspension portfolio, helping ensure the part matches the original application requirements. The joint is tested for extreme temperature exposure and salt spray resistance, supporting durability in harsh road conditions. This part cross-references MOOG Chassis Products K6540 for the same application.
Compatible With 1999-2006 Chevrolet Silverado 1500, front upper; 2000-2006 Chevrolet Tahoe, front upper; 2000-2006 GMC Yukon, front upper; and other listed GM applications including Chevrolet Avalanche 1500, Suburban 1500, Cadillac Escalade, and GMC Sierra 1500. Delphi TC1625 is also a fitment match for 2003-2008 Chevrolet Express 1500 and 2003-2005 GMC Savana 2500 front upper service.
Common Repair Uses
- Front suspension looseness or play
- Clunking or popping from the upper control arm area
- Uneven tire wear related to worn steering geometry
- Steering wander or reduced front-end stability
- Service replacement for worn OE-style upper ball joints
Installation Notes and Tips
Fits 1999-2006 Chevrolet Silverado 1500, Front Upper; 2000-2006 Chevrolet Tahoe, Front Upper; 2000-2006 GMC Yukon, Front Upper; and the other listed GM truck, SUV, and van applications. Verify the vehicle’s front upper suspension configuration before installation, since the fitment notes specify non-adjustable, greasable applications. Press-in installation requires proper suspension service tools and correct torque procedures for the castle nut and cotter pin retention.
Quality Assurance
Delphi builds this ball joint using OE-oriented engineering and validation methods, including temperature cycling below -40 degrees C and above 120 degrees C, plus 720 hours of salt spray exposure. That testing, along with dimensional and material analysis, supports consistent fit and long-term service performance in the specified applications.
