  • OE-derived engineering: Delphi applies its OE steering expertise to the aftermarket, with parts validated below -40°C and above 120°C and exposed to 720 hours of salt spray; dimensional and material analysis targets OE-level compatibility.
  • 100% inspected: control arms undergo crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Precision ball stud: studs are machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded and corrosion-protected: consistent robotic welds, with anti-corrosion protection applied for corrosion prevention and enhanced appearance.
