What it does
Two jobs. Connect all four tires to one source and inflate them together, evenly — the group-run favorite in our air-down guide. Or run multiple air lines or tools at once: an air tool at one end of the truck and a tire filling at the other, or a group setup where more than one person needs air without waiting in line.
Good to know
- Not vehicle-specific: it works on any truck with a 12V battery.
- Tire size does not enter into it — our onboard air guide says it isn't sized for bigger tires or a specific wheel setup.
- Pair it with a twin: our air-down guide says dual motors roughly halve air-up time, and the Twin Compressor is one of the compressors this page pairs it with.

Questions before you buy
Do I need a compressor to use it?
Yes. It inflates all four tires from a single compressor connection, so plan on a compressor. This page pairs it with the Twin Compressor ($369.99) and the Bunker Compressor Kit ($529.99).
What colors does it come in?
Black, Red, Blue, Green, or Orange — choose your color at checkout. Our onboard air guide suggests the colors double as an easy way to color-match a hose to the rest of your build.
Can I return it, and what does shipping cost?
Yes. Our Return Policy covers universal gear: “These are not vehicle-specific, so they can be returned within 30 days of delivery, new and unused, in the original packaging”. Return shipping is paid by the customer unless the item arrived damaged, defective, or was sent in error. Outbound: $39.98 flat-rate US shipping, tracked.
