Delphi TC7425 Suspension Trailing Arm

The Delphi TC7425 is a replacement suspension trailing arm engineered to restore precise wheel location, alignment geometry, and ride quality to OE standards. As a critical component of the rear suspension system, the trailing arm links the rear axle or wheel hub to the vehicle's chassis, maintaining proper wheel travel and resisting braking and acceleration forces.

Key Features:

• OE-Grade Engineering: Designed to match original equipment specifications for a direct, no-modification installation
• Robot-Welded Construction: Consistent weld quality throughout for long-term structural integrity and reliable performance
• 100% Crack Detection: Each arm undergoes ultrasonic flaw detection to ensure materials meet OE specifications
• Anti-Corrosion Protection: Cataphoretic coating applied to resist rust and extend service life
• Extreme Temperature Tested: Validated to perform below -40°F and above 248°F for year-round reliability
• Salt Spray Tested: Exposed to 720 hours of salt spray to validate corrosion resistance
• Micron-Tolerance Machining: Precision-machined mounting points ensure proper fitment and smooth operation

Delphi's extensive dimensional and material analysis ensures tight compatibility between the aftermarket replacement and the original part. The TC7425 trailing arm is a trusted solution for professional technicians and DIY enthusiasts seeking a durable, long-lasting suspension repair.
