    2017 GMC Denali 2500
  1. This truck is 10,000 lbs stock add a trailer and you need some stopping distance. I will only be using these when absolutely necessary, otherwise the original horn will work fine.
  2. Just finished installing Kleinn Air Horns model GMHD-734 on my 2017 GMC Denali 2500 HD, I was selected to be a Kleinn Test Team Member in order to review this new product kit. Before I purchase this kit, I called Kleinn because I was not sure which horns to get, I spoke to Gary who was very helpful in telling me difference between the beast Model 230 and the Demon model 730 horns. I decided to go with the Demon 730 Horns as these are metal and will sound closest to a real train horn. The install of this kit went fairly well and is 100% bolt on and requires no drilling, welding or vehicle modification. The compressor and tank bolt up perfectly in front of the rear wheel well on the passenger side and the horns fit right behind the front bumper. The brackets are heavy duty and It all looks factory; the best part is they sound very close to a real train. Here are some photos of the install.
