What it does
What the tank adds: our air-down guide describes tank-based kits as stored air for faster fills and running air tools at camp. The twin compressor in the case brings dual motors, which the same guide says roughly halve air-up time compared with a single, and our onboard air guide adds that a twin opens the door to air tools that need sustained flow rather than a quick burst.
Good to know
- Not vehicle-specific: it works on any truck with a 12V battery.
- Airing down at the trailhead? Our air-down guide's starting points: 20–25 PSI on graded dirt or washboard, 15–18 PSI for general trail and rocks, 12–15 PSI in sand.
- Air back up before highway speeds — the guide warns that low pressure at 70 mph overheats and destroys tires.

Questions before you buy
Will it work with my truck?
If it has a 12V battery, yes. The kit is not vehicle-specific; it works on any truck with a 12V battery. Unsure? Email us before you order — we would rather answer a question than process a return.
Who is this kit for?
Groups and air-tool users. Our onboard air guide says a twin makes sense once you are adding air tools or airing up for a group. If you mostly air up solo after an occasional trail day, the Single Compressor + Line Kit ($299.99) handles that without issue.
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.
