Take the guesswork out of rear suspension work with the Monroe Quick-Strut 171139 Rear Suspension Strut and Coil Spring Assembly. This complete strut and coil spring assembly arrives as a single, fully assembled unit — strut, application-specific coil spring, and preassembled upper mount together — so you can replace worn rear struts without a spring compressor. It's a direct-fit replacement for the 2007-2017 Ford Expedition and 2007-2017 Lincoln Navigator (see the Buyer's Guide tab for engine details).
All-in-one repair: Includes the components needed for rear strut replacement in one fully assembled unit — quicker, safer, and easier, with no spring compressor required.
Restores ride height: The application-specific coil spring is calibrated to the OE design to help restore ride height and support the vehicle's weight.
Vehicle-specific design: Fit checked and ride tested; the coil spring, mount, and strut are engineered for this vehicle profile to help reduce body sway, vibration, and road harshness for improved control.
Premium upper mount: An OE-style upper strut mount helps deliver smooth steering and guards against noise, vibration, harshness, and memory steer.
A protective coating resists rust and corrosion, and it's backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
