(2007-2018 Jeep JKU 4WD V6)


We are proud of the fact that most of our kits fit any vehicle, but let's be honest, even our most low profile train horn kits can be tricky for a lot of Jeep Wranglers. For as long as we have been making horn kits, customers have asked for an all-in-one solution for Jeeps. We have heard you and after years of research and development, we proudly bring you the loudest Jeep air horn kit you can buy, the Wrango JKU Horn Kit! For our first vehicle-specific kit, we made sure to pack as much power as we possibly could in our Wrango JKU Kit. With the HB-2 air compressor, dual Shocker Horns and our 2 Gallon Tank on a dual bracket system, not only is our Wrango kit ridiculously louder than any vehicle-specific system you have ever heard before, installation is quicker and easier than any of our other kits with only about a 4 hour install time!  

We take the guesswork out of the installation process by providing clear and easy to understand step-by-step instructions and include everything needed from start to finish, right down to the pre-riveted rivet nuts in the legs of the tank. The dual bracket system fits perfectly on to your transfer case and evaporation canister, keeping a low profile and making sure the attention is all on the sound. While easy installation is great, it doesn’t matter if you are running a wimpy horn. Anyone that already owns a HornBlasters kit knows you never have to worry about that with one of our kits. Rocking our #2 and #4 Shocker XL bells, the Wrango JKU is not for the faint of heart. These fiberglass-reinforced ABS bells might not look like much to the uninitiated, but nothing prepares you for the massive sound that comes from such a compact kit.

Having onboard air kits for your train horn is great, but having onboard air for any situation, such as tire inflation offroad or blowing up a raft for the camping trip, should be a must-have for any Jeep Wrangler owner.. Jeep owners, this is the kit you have been waiting for. With customization being such a big part of Jeep culture, this is the premier air horn kit to own. The Wrango train horn kit for Jeep Wrangler JKU delivers the same world-class quality you have come to expect from HornBlasters in a convenient all-in-one solution that doesn't pull any punches.
