- Forged strength: Manufactured with high-quality forgings for added strength and smooth joint operation.
- Chloroprene boot: A chloroprene rubber boot improves durability and helps prevent premature failure.
- Precision-machined: Machined to micron tolerances for durable, smooth operation.
- Corrosion protection: Anti-corrosion protection is applied to each part for corrosion prevention and improved appearance.
Delphi applies its OE expertise to the aftermarket steering portfolio: parts are tested to withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility. A worn ball joint may show up as clunking over the front suspension, loose steering, or uneven tire wear — if the original joint is the cause, this replaces it.
