Installation Notes and Tips

Verify the rear left upper forward position and compare the original arm dimensions before installation. Because mounting hardware is not included, reuse or source the correct hardware as needed. A professional alignment is recommended after replacement to confirm rear suspension geometry and tire wear settings. Confirm vehicle-specific notes such as Strut Rod or without Sport Package applications before ordering.

Quality Assurance

Delphi tests steering and suspension components under extreme temperature and corrosion conditions, including exposure below -40 degrees C, above 120 degrees C, and extended salt spray testing. The brand also uses dimensional and material analysis to support OE-level fit and function for aftermarket replacement.
