- OE-derived engineering: Delphi applies its OE steering and suspension expertise to the aftermarket, with parts validated below -40°C and above 120°C and through 720 hours of salt-spray exposure, plus dimensional and material analysis for OE-to-aftermarket compatibility.
- Quality-verified: Control arms undergo 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: Ball studs are machined to micron tolerances for durable, smooth joint operation.
- Built to last: Robot welding delivers consistent construction, and anti-corrosion protection is applied to each part for corrosion prevention and improved appearance.
Signs this part may need replacing include clunking on acceleration or over bumps, loose or wandering steering, uneven tire wear, and play in the ball joint. Diagnose the cause before replacing.
