This kit is not to be underestimated. Despite it being a 2-gallon (7.5 liters) reservoir, the included air pump is a powerhouse. This Viair 485C air compressor is the most heavy-duty compressor that Viair offers. It’s designed specifically for smaller vehicles where larger tanks may not fit. The compressor is overpowered (200 PSI capable, constant duty, and powerful!) to ensure the best reliability, and only pulls 22 amps at its peak.

An increasing number of people are using this for more than just blasting horns! With a system like the 2485K, you can also use the air supply to:

  • Adjust Tire Pressure
  • Moderate Pneumatic Use
  • Inflate Water Toys and Safety Gear
  • Supply Air to Load Leveling Bags
  • Supply Air for Differential Lockers
  • Blow up Kids Toys
  • And lots more!

Please note that if you use horns, you will still need an air valve kit to connect the system properly. 

Unlike some other air systems, HornAir kits come with 10 and 18 gauge wire, and a complete wiring kit including a fuse holder. This takes out the guesswork on your end and helps ensure your system is installed correctly. Another great feature of HornAir systems is that they come with a standard 1/2in OD push-to-pull fitting. This means the horns you hook up with get all the air they need.

RECOMMENDED FOR USE WITH THE FOLLOWING:

Shocker S4 Train Horns (Part number: AH-S4)
Outlaw Series Train Horns (Part numbers: AH-O3, AH-03B, AH-O5)

     Please Note: This HornAir system is not recommended for AirChime horns. We recommend using at least a 4-gallon tank with larger-scale train horns like the P3, P5, K3, and K5; however, this kit is perfect for HornBlasters Shocker horns and Outlaw and Bandit series horns.
