Onboard Air Upgrade Kit: Digital Inflator, Air Hose & Auto Deflators
Description
Compressor and Mount Done? Here's What's Missing — Save 8%
Three things to know before you build:
- No compressor, no bracket. This kit is the air tools only, built for people who already have onboard air installed. If you still need the hardware, start with our Complete Onboard Air System or the Onboard Air Install Kit instead.
- Pick your hose reach. Choose the length based on where your compressor actually sits. Under the hood on a 4-door usually means 35' or more to walk all four corners.
What's in Your Kit
Tire-Rite Digital Air Inflator/Deflator
Most people are still running the basic chuck that shipped with their compressor. This replaces it with a backlit digital tire inflator deflator that reads pressure at the valve stem rather than back at the compressor — so the number on the screen is the number in the tire.
One tool inflates, deflates and checks pressure, one-handed. Choose HD or Pro, straight, 90-degree or flex chuck, and a 24" or 36" hose. The longer hose lets you hold the display at eye level while the chuck stays clipped to the valve, which matters when your compressor is mounted low or behind a seat.
Tire-Rite WorkHose Lightweight Air Hose
The problem nobody mentions until you hit it: once a compressor is hard-mounted, the factory line stops three feet short of the rear tire and you end up moving the vehicle to finish the job.
Choose 25', 35' or 50'. Go 3/8" for faster flow on longer runs, or 1/4" for a lighter air line that coils tight and stores small.
Tire-Rite Deflate-Rite Valves (Set of 4)
Screw one onto each valve stem, set your pressure, walk away. All four tires drop to target at once and stop on their own. No crouching at each wheel, no checking and rechecking, no ending up at 22 PSI when you meant 15.
This is the half of the cycle that almost nobody buys until they have spent a season doing it by hand. A tire deflator that works unattended turns a fifteen-minute job into something that finishes while you drink your coffee.
Keeps the inflator, valves and fittings in one place instead of loose in the back of the truck.
Why the Tools Matter as Much as the Compressor
An onboard air system is a chain. Most builds put serious money into the compressor and then run the cheapest possible gauge on the end of it.
The result is a setup that can move a lot of air but cannot tell you how much. You inflate by feel. You deflate by pressing a valve core with a key and guessing. The expensive part of the system is doing its job perfectly while the two-dollar part quietly ruins the result.
This kit fixes the end of the chain. Accurate measurement, enough reach to work the whole vehicle, and deflation that runs itself.
Air Down, Air Up
Knowing how to deflate a tire correctly is half of running trail pressure — and doing it by hand is why so many people skip it.
At the trailhead, the Deflate-Rite valves bring all four tires down at once and stop where you set them. Lower pressure means a longer contact patch, real traction on rock and sand, and a noticeably softer ride over washboard.
On the way home, your compressor and the digital inflator bring everything back to street pressure in minutes. No gas station queue, no coins, no guessing.
That is the full air up air down cycle. The compressor makes it possible; these tools make it fast enough that you will actually do it.
Better Than a Portable Inflator
A portable tire inflator is a fine backup and a poor primary. It has to come out, get set up, plug into a socket, and pack away every time. The good ones are slow on 35-inch tires and the cheap ones overheat before they finish the third corner.
If you have already installed onboard air, you have solved that problem. What you have not solved is precision and reach — and that is exactly what this kit adds. The best tire inflator is the one already plumbed into your rig, with an accurate gauge on the end of it.
Fits Every Rig
Every item in this kit is universal. No fitment to check, no year to match, nothing to measure.
That also makes it the one air kit you can buy for someone else. If you are shopping for a Jeep or truck owner and do not know what they already have bolted to their build, this is the safe answer — it works with any onboard air system, from an ARB twin compressor to a tank-fed setup.
One Order Instead of Four
Buying the upgrade together takes 8% off the total.

Two Brands, One System
Mountain Offroad has been building off-road parts in Colorado since 1982 — brackets, skid plates, bumpers and armour, all designed, cut, welded and finished here.
Tire Rite makes the tools at the other end of the air line: inflators, gauges, tire deflators and hoses built for people who use them in the dirt rather than in a garage. Precise enough to trust and simple enough to work with cold hands.
We partnered with them because a compressor is only as good as what you attach to it. Their gear is what we run on our own builds, and putting it together as a kit means you get one order and one price instead of four separate decisions.
