Product Overview
Each air strut combines an air spring with a damper to support ride height and help control wheel movement.
A leaking air spring may cause the front end to settle overnight or the compressor to run too often. Ride-control variants and front mounting designs can differ even within the same chassis.
Verify chassis VIN, AIRMATIC option, left/right strut OE numbers and whether the assembly includes electronic damping. Do not use for conventional spring suspension.

What if my model year appears above but the part looks different?
Do not install it based on the model year alone. Factory equipment changes by engine, build date, trim, mounting style, and option package. Match the original part number and physical connections first.
