Hi, as a contractor in West Fargo, ND and who is on the road a lot, (and my truck is my office) I need a quiet area to work. We know most GM trucks tend to have excessive wind noise when there is a cross wind or traveling at highway speeds. I would like to recommend if you have wind noise in your 1999-current GM truck to purchase this easy to install kit. I came up with this kit to eliminate all the wind noise and it really works! We also can make kits for many makes and models with a special request. This kit does not replace the factory weatherstrip, this is a separate product. Q. REASON THEY HAVE WIND NOISE? A. At highway speeds with a cross wind you can hear a lot of wind noise, which is actually caused by the door frame losing contact with the factory weatherstripping. This kit allows the door to seal tight at highway speeds or high winds. EASY 5 MINUTE INSTALL ONLY A UTILITY KNIFE OR SCISSORS NEEDED!! KIT INCLUDES: -Step By Step Instructions -Pre-Cut Wind Noise Kit (3M Extruded Weatherstrip) for Your Model (Regular Cab, Extended Cab or Crew Cab (Also works for Tahoe and Suburban)
