Installation Notes and Tips

Verify chassis break points and position before ordering, especially on Audi 90 and Audi Quattro applications with chassis-specific notes. Inspect related suspension components, alignment settings, and mounting points during replacement. Because the ball joint is not included, confirm whether the existing joint is serviceable or requires separate replacement before installation.

Quality Assurance

Delphi tests suspension components across extreme temperature ranges and extended salt-spray exposure to evaluate durability and OE-level performance. The brand also uses dimensional and material analysis to support proper fitment between the original and replacement part.
