Air System Accessories

Air System Accessories: onboard air and the bits that keep it running

An onboard air system carries a compressor, tank and lines so you have pressurized air on the vehicle without hunting for a gas-station pump. That means airing tires back up after a trail run, seating a bead, running air tools, or feeding a set of loud air horns. The air system accessories here are the complete kits that make that possible plus the fittings and airline that tie them together. If you have ever bled a leaking air line at a fitting, you know the small parts matter as much as the compressor.

What ThreePiece stocks

This is a small, focused category: 3 products in stock from 2 brands - Kleinn Air Horns and ARB. Prices currently run from $56 to $1,640. That is the live range for what is on the shelf right now, not a standing offer.

The two Kleinn kits are complete onboard air systems bundled with Model 730 horns. One is built for the 2017-2020 Ford Raptor and one for the 2020-2024 Chevrolet Silverado 2500 HD / 3500 HD. At the other end of the price spread sits the ARB Airline Service Kit - 5mm Blue, the fittings-and-line side of an air setup.

How to choose

The decision here is really about how much of the job you want done for you:

  • Vehicle-specific complete kit: the Kleinn systems are matched to a named truck, so the mounting and horn hardware is worked out for that platform. Pick the one that matches your make and year.
  • Service and repair parts: if you already run air and need to route, extend or fix a line, the ARB service kit is the low-cost end of this list and answers a different question than a full system.

Fitment data here covers one Ford Raptor application directly, with the Chevrolet Silverado HD kit named in its product title. If your truck is not one of those two, treat this as a starting point and confirm before you order.

What else you may need with it

Air systems live alongside the rest of an exterior build. If your project is a truck, browse the wider Truck and SUV range and the parent Exterior section. Owners fitting onboard air often add Lighting, an LED Light Bar, and recovery-minded gear like Tow Hooks. Trail and tow trucks also tend to pick up Mud Flaps and upgraded Mirrors at the same time.
