    I'm not sure what's its purpose on a K5, but part of mine got torn off so I just removed it completely and I haven't noticed anything different.

    Purely cosmetic. It covers up the front of the springs and such. If you have a sweet looking suspension, it may look better with it off. I painted mine to match the truck and I think it looks pretty good, so I've left mine on. Without it, the factory tow hooks are much easier to use

    The front air dam is there to deflect the air from coming up from under your radiator. It was designed to move the air downwards to make it so the fan will pull air thru the radiator.

    I'll tell you that I've had mine off for a few years now real problem. Sometimes the truck will tell me it's has an upset radiator (radiator overflows), the gauge says it's in normal range (gauge is working fine). I have the most trouble when I'm towing something or in slow traffic. I'm thinking of making a small deflector that is mounted under the radiator and is small enough that you cann't see it underneath.

    Don't worry about the air dam. It was designed to deflect air downward from the bumper to keep debris etc. from getting into the engine bay (keep the engine shiny!). Mines been off for over five years with heavy wheelin' in the mountains and mud of Maine with no problems.

    Why do people keep calling it a Bronco!!!!!

    Had mine off for 3 years. No problems with radiator heating up. And it shows off the red bushings on the front springs, looks good against the black body.

    actually, the purpse of a front air damn is to prevent wind from flowing under a car. If you go to fast in a car and you dont have an air dam all the wind flowing underneath will create lift and make it easier to lose control. There is absolutely no reason to have one on a blazer.

    i never previously had one. but when i put one on, it made a difference in high speed stability, 80+. i know, i know how often do you cruise at that speed? ...almost never. but, if i wanted to...it would be more stable...hehehe.

    Here in Colorado, where the speed limit on the interstates is 75, we get to travel at those speeds quite regularly! [​IMG]

    Speed limit on the interstate is 70 around here so 80 is not all that big a stretch ........ [​IMG]

    I took my air dam off and my gas milage went down a bit. Also didn't like the way it handled at freeway speeds. So I put it back on. The speed limit around here(northeast Nevada) is 75 and the cops usually dont bother you unless yur doing over 85. Everybody drives fast in their 4x4s. Its funny to see the looks you get from out of staters doing 70 or 75 as they get blown off the road by all the big K5s ,surburbans, and other 4x4s passing them. Around these parts everyone owns a 4x4. Many have air dams. But iI dont think you need one if you drive slow and they are mostly useless if your truck is lifted
