Good To Know

Q: Do I need to replace both front struts at once? A: This set includes two front struts so both corners can be serviced together. Replacing them as a pair helps keep front ride height and damping balanced.

Q: Does an ADS-equipped vehicle need any programming after install? A: Some vehicles may require a scan tool to clear suspension codes or recalibrate ride height after installation. Confirm the exact procedure for your model before fitting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
