Good To Know

Q: Will I need to reset the suspension after installation? A: Many vehicles require a scan tool relearn or calibration after a strut replacement so the ride height sensors read correctly. Check your model's service procedure before driving.

Q: How do I confirm this strut fits my car? A: Match the OEM numbers 2123202038 and 2123203438 against your existing part or VIN lookup. Fitment can also depend on whether your car is 4-Matic with factory air suspension.

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