Installation Notes

Install on the rear left position only and verify the vehicle’s suspension configuration before ordering. Inspect the sway bar, mounting points, and adjacent bushings for wear during replacement. Because this link uses bushing-style ends, proper seating and torque are important for quiet operation and long service life.

Quality Assurance

Delphi subjects this part to extreme temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. Those validation steps support corrosion resistance and durability for everyday driving conditions. Delphi’s OE-focused engineering approach is used to align aftermarket fit and material selection with original equipment expectations.
