Review on 🔊 Chrome Kleinn Air Horns HK2 Complete Dual Truck Air Horn Package by Shawn Hill

This kit exceeded my expectations for volume. Give yourself more installation time to get it right! I installed this on a 4300 International Truck. First I installed the pump in the bottom of the cabin, bad idea, very noisy! I made a bracket and attached it to the frame! I can hold out here, it works now! The standard horn on the truck sucks! Now it sounds like a big truck!
