Detailed Description

StrongArm 4191 is a back glass lift support made for rear window glass service on the Ford Expedition and Lincoln Navigator. It is a specific-fit replacement, not a universal support, and its dimensions and end fittings are matched to the listed vehicle applications. The pressurized cylinder design helps hold the rear glass in position while allowing controlled opening and closing action.

This part cross-references Monroe Shocks & Struts 172286 for the same application. If you are replacing a worn rear glass support on a 2003-2006 Ford Expedition or 2003-2006 Lincoln Navigator, part number 4191 provides the fitment and hardware style needed for the original mounting points.

What It Helps Fix

• Rear glass that will not stay open
• Back window glass that drops too quickly
• Weak or inconsistent lift support pressure
• Binding or rough rear glass movement
• Noise or instability when opening the rear glass

Installation Notes and Tips

Verify the vehicle year, make, and model before ordering. Confirm the existing mounting style uses 10mm nylon ball socket ends and compare the compressed and extended lengths to the original support. For proper rear glass support and balanced operation, replace lift supports in pairs when servicing the liftgate glass system.

Quality Assurance

StrongArm lift supports are custom engineered and manufactured beyond industry standards to support smoother operation and longer service life in automotive applications. Part number 4191 is built for the specified Ford Expedition and Lincoln Navigator rear glass fitment.
