WeatherTech Side Window Deflectors
2002 Ford F-350
Crutchfield Customer Review (What's this?)
Installed in under two minutes. Very easy. Rear windows installed with tape (Ford Super Cab) and are for looks only - non functional
Pros: easy, quick installation
Cons: Window was hard to roll up 100%, because the deflector mounts in the channel, but channel opened up after awhile.
