Understanding the Need and Function of Rear Window Deflectors

Posted by

So, what is a rear window deflector? In general, there are 2 types – the rear window air deflector, which forces air down the back windows of vans and SUVs to keep that window clear of debris / and the rear window deflector, which helps protect your back seat interior from sun damage and heat buildup. You usually see the latter on the back windows of pickups and cars.

A rear window air deflector will greatly reduce the dust, dirt, and winter muck that accumulates on the van or SUV back windows. By design, they direct the air flow down and across that window while you’re driving to keep all that debris away!

The rear window deflectors job is to shade the interior of truck cabs and cars, keeping them cooler, and deflecting the UV rays from the sun. They are also very handy at reducing headlight glare from behind when you’re driving at night. Another nice bennie if you live in the northern regions is that they do a lot to keep the snow and ice off of your back window. These guys can often look like, and are often called, window louvers, as the basic functions are the same.

Both types of these window deflectors are made to custom fit your vehicle, so you get a solid fit and maximum protection. They are generally made of impact resistant ABS plastic, are paintable, and will handle a third brake light. Installation is a snap, with no drilling required on most units. Many of the newer vans and SUVs are coming with these as a stock piece. Certainly makes good sense!

So now that you know a little bit about these, bring up your favorite aftermarket auto accessories web store and do a little shopping around. Then pick up the right rear window deflector for your ride! You’ll be glad you did!
