Delphi applies its OE steering expertise to the aftermarket, testing to the extreme for OE-level performance:
- Extreme-condition tested: validated below -40°C and over 120°C and exposed to 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility.
- Micron-tolerance ball stud: machined to micron tolerances for durable, smooth joint operation.
- Fatigue tested: the tie rod is fatigue tested to help avoid failure.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Delphi also includes the necessary accessories for a complete job. Signs the original may need replacing include loose or wandering steering, uneven tire wear, or clunking from the steering linkage; if a worn tie rod end is the cause, this Delphi track rod end replaces it.
