Detailed Description
StrongArm 4191 is a back glass lift support made for rear window glass service on the Ford Expedition and Lincoln Navigator.

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.
