Delphi applies its OE steering and suspension expertise to this aftermarket part, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket part. Delphi tests to the extreme for OE performance, exposing parts to temperatures below -40°C and over 120°C and to 720 hours of salt spray.
- Verified materials: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
- Robot welding: used for consistent performance and quality.
- Machined ball studs: ball studs machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.
Worn control arms may signal their need for replacement with clunking from the suspension over bumps, uneven tire wear, or loose, wandering steering. If a failed rear upper control arm is the cause, this replaces it.
