What exactly dose the roof visor do? I mean is it just for shade or does it have some aerodynamic effect like extra down force or better air flow? I'm asking because I see them all over the place and don't know why the green strip on the windshield isn't good enough. Most online ads say its aerodynamic but does it ad any thing to it other then shade.LOL

I should clarify I am talking about the one the mounts over the windshield out side of the truck.

 

Personally, I think they look good but I couldnt see there being any benefits to having one not even much extra shade ,but who knows.

 

yeah the do look nice. I think the ones with the lights built in are real cool at night

 

Those are to let you know the driver is gay.

 

LOL kind of like ladder racks points out a douche LOL

ok i take that back its getting late. but really man whats with you and the jokes LOL

 

I'm trying to help.

 

LOL ok then carry on.

 

They really don't help much I had a 94 that had one on it and when it was raining water drips off. Of it on to your window

 

I think it's so if u had cab marker lights than the reflection won't hit your hood and distract you at night. Just a guess?

 

It adds about 15 horsepower.
