KUIPERAUTO Rear Strut/Shock Assembly Pair for 2007–2017 Ford Expedition & Lincoln Navigator — Pre-Assembled, Corrosion-Resistant

KUIPERAUTO rear strut and shock assemblies deliver complete, pre-assembled suspension replacements engineered to fit 2007–2017 Ford Expedition and Lincoln Navigator models without electronic suspension.

These pair rear struts with coil springs and shock absorbers arrive ready to install, replacing OEM number 171139. Each assembly includes the strut, coil spring, top mount, protective boot, bumper kit, spring seat, and isolator so you avoid piecing parts together. Built from advanced alloy steel with electrophoretic paint, the assemblies prioritize corrosion resistance and durability for long-term road performance.

Will these KUIPERAUTO assemblies fit my 2007–2017 Ford Expedition or Lincoln Navigator?

Yes—these strut/shock assemblies are specifically designed for 2007–2017 Ford Expedition and Lincoln Navigator vehicles that do not have electronic suspension systems. They match OEM 171139 dimensions and mounting points for a bolt-in replacement.

• Compatible years: 2007 through 2017
• Models: Ford Expedition and Lincoln Navigator (without electronic suspension)
• Direct OEM replacement for part number 171139
• No cutting or frame modifications required

How do these pre-assembled struts simplify installation?

Because KUIPERAUTO ships the components as complete assemblies, you won’t need to compress springs or source additional mounting hardware. That reduces installation time and lowers the risk of assembly errors compared with buying separate parts.

• Comes pre-assembled with spring, mount, boot, bumper, seat, and isolator
• Standardized sizing to align with factory mounting points
• Typical install requires common hand tools and a standard lift or jack
• Designed to replace original units directly—no modifications needed

What materials and testing ensure these shocks last?

KUIPERAUTO uses advanced alloy steel and a corrosion-resistant electrophoretic finish to protect the strut body from rust and wear. Each unit goes through high/low temperature cycles and air spring blasting tests to verify durability and consistent damping performance under varying conditions.

• Alloy steel construction for improved strength
• Electrophoretic paint finish to resist corrosion
• High/low temperature and air spring blasting quality checks
• Engineered damping for a stable ride across road conditions

What should I expect in ride quality and maintenance?

These assemblies are engineered to restore factory-style ride control and reduce excessive bounce or body roll associated with worn struts. Routine inspections for leaks, mounts, and boot condition will keep the system functioning reliably over time.

• Improved damping to stabilize ride and handling
• Corrosion-resistant finish lowers long-term maintenance needs
• Replace in axle pairs for balanced performance
• Inspect boots and mounts during oil/tires service intervals

Who is this for? KUIPERAUTO rear strut and shock assemblies are aimed at owners and mechanics of 2007–2017 Ford Expedition and Lincoln Navigator vehicles without electronic suspension who want a direct-fit, durable replacement. They suit DIYers who prefer bolt-in parts over component assembly and repair shops that need reliable, OE-matching replacements for restoring suspension performance and handling. If you require exact OEM compatibility (171139) and long-term corrosion resistance in harsh environments, these assemblies are designed for your application.
