This premium heavy-duty kit delivers an unmatched combination of spine-tingling volume and professional-grade utility, and everything needed arrives in one box for a professional and flawless setup. We custom engineer chassis-specific mounting brackets that are proudly made in the United States of America and bolt our genuine Kleinn components directly to existing factory locations. Using common hand tools, anyone can install this system without drilling a single hole, ensuring a true 100 percent bolt-on installation. This high-performance package features the legendary, earth-shaking blast of our Demon model 730 triple train horn. Providing the pneumatic power is a high-output Kleinn waterproof air compressor paired with a Cortec coated three-gallon air tank, creating a versatile onboard air station capable of inflating large tires, powering air tools, or operating air suspension bags. For added utility, the package includes a remote-mounted quick connect, a 30-foot high-pressure tire inflator hose, and a dedicated storage bag. For enthusiasts looking to maximize their performance, the entire setup can be upgraded to deliver an even louder blast by adding the part number 6890 Ultra BlastMaster valve upgrade kit.

The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.
