I Have a Go Rhino Guard 3000 series Brushgurard for a 99 Blazer.. nobody make a direct fit for a bravada that I liked so I had to drill some "custom" holes lol to make it fit. the one I got has the headlight wrap-arounds but apperantly the front end of a blazer sits about 2ins hight so they don't line up w/ the lights just right but I'm gunna be putting a 2in BL on it soon so I'm hoping that it'll all balance out then lol..
This is it right HERE!!!

 

To be honest I have a Yakima Mega Warrior on my jimmy (the huge basket) and I havin't noticed any difference on mpgs at all. I track every fill up. I need to find a smaller basket because mine is wider than my roof haha

 

I too haven't noticed much of a difference at all. I can still pull almost 20 mpg during the summer.

 

Yeah, mine get me 16 mpg at 80 mph. And I agree on the hight issue, I got within 1 in. of a parking garage roof. I don't even have a lift.

 

The brushguard is a Go! Rhino one for a 99 blazer. it has the headlamp guards & halo bar to but until I get the 2"BL done they sit way off center of the headlights & just look goofy. Go!Rhino isn't cheap really thou. But know body makes a brushguard for the bravada's besides a bull guard. So I had to do alittle moding so now its "Custom!" lol.
& the only "aerodynamic" lights Iv ever heard of was the tail lights on a belair! lol It's Blazer/Jimmy/Bravada bud! they get sh*tty gas mpg. we drive'em cuz we love'em not to save gas lol.
