Mine has this spoiler thing but let me tell you it doesnt work. Ususlly they are there to deflect air around the rear window, but my rear window cant go 2 miles on a clear day without every piece of road dirt sticking to it. Its like it helps direct the dirt there.

 

if you are looking for it to help keep dirt off the back window it doesn't work. I have a 06 Tahoe with it and it does nothing to help.

 

nah, not so much for keepin dirt off, just to give it a different look than 90% of the other tahoe's/yukons on the road. all of 'em from 2000-2004 are the same so itd be nice to have the newer peice, thats all.

 

I plan on having my rear vents and the glass piece painted to match the truck. I don't post here very often you can see pictures of it on www.showtruckscene.com
