Unity 18-561001 Rear Left Non-Electronic Air Strut Assembly

Rear Left Air Strut Assembly

The Unity 18-561001 is a brand-new non-electronic air strut assembly built for the rear left corner of a vehicle. It arrives with the solenoid valve included so the unit can be fitted without sourcing additional components. Unity draws on over 50 years of aftermarket suspension experience to deliver a direct replacement that restores factory ride height and damping control.

Fits 2007-2016 Navigator and Expedition

This assembly suits owners of the 2007-2016 Lincoln Navigator or Ford Expedition who need to replace a worn or leaking rear left strut. It is not for the front axle, the right-hand side, or vehicles equipped with electronic suspension controls that require a different valve configuration. Buyers with other model years or different suspension architectures should look at a different part.

Restores factory air suspension function

The unit provides the air spring and damper needed to support the rear left corner and maintain proper ride height under normal load conditions. It runs out of headroom when the vehicle is heavily laden beyond its gross vehicle weight rating or when the compressor system cannot supply sufficient pressure. Installation re-establishes the original suspension travel and load-levelling behaviour.
