Unleashing a blast of sound from powerful air horns, filling a set of large tires after they no longer need to be aired down, powering pneumatic tools – all are possible when you outfit your GMC Sierra with aftermarket 1999-2017 onboard air. The 1999-2017 onboard air systems you’ll find on AmericanTrucks include high performance, modern air compressors with lots of useful features – delivering 2-3 cubic feet of air per minute in many cases, and supplied with long rubber hoses, pressure gauges, reusable air filters, and so on. There are also 1999-2017 onboard air systems with horns, which feature components that help with the installation and operation of air horns, train horns, and similar sound upgrades. These include such items as long-range remote controls letting you activate the air horns from hundreds of feet distant, as well as valve upgrade kits to deliver more air to multiple-trumpet horns.
