ALL-TOP 4-Way Inflation System Review: 4-Tire Air
The ALL-TOP 4 Way Inflation System airs up or down 1–4 tires at once with ±0.1 PSI precision. It's $189.99, rated 4.6 stars from 172 ratings, and one owner reports filling four 35-inch tires from 10 to 37 PSI in about five minutes with an ALL-TOP twin-head compressor.
Overview
The ALL-TOP 4 Way Inflation System is a four-tire inflate/deflate manifold that connects to your existing air compressor. It's listed at $189.99 and holds a 4.6-star rating from 172 ratings. The system lets you inflate or deflate 1–4 tires simultaneously with ±0.1 PSI precision and automatically equalizes pressure across all connected tires.
For overlanders who air down for trails, the appeal is simple: no more bending over each tire with a separate gauge. One owner who airs down for trails reported filling all four 35x12.5x17 tires from 10 PSI to 37 PSI in about five minutes using an ALL-TOP twin-head compressor, not counting setup and removal time.
ALL-TOP 4 Way Inflation System
Highlights
- Multi-tire air-down / inflate kit
- Manual trail control
- Set-and-watch deflation
- About $189.99 list
Best for
- Airing four corners together on trail days
- Overlanders who already carry onboard or portable air
- Drivers OK watching the gauge while air dumps
Strengths
- Moves multiple tires in one setup instead of walking the truck tire-by-tire
- Simple mechanical control once you learn the preset / valve rhythm
- ALL-TOP kit sits in the overland / recovery gear class rather than a glovebox pencil
- Fewer electronics to fail in dust and weather than a full digital manifold
Watch-outs · not ideal when
- Needs a plan to air back up — this is not a compressor
- Hose spaghetti and setup time before the first dump
- Easy to overshoot target PSI if you walk away from a wide-open dump
- Trail abuse (sand, rocks, tossed in a drawer) wears seals and QDs over time

“4/5 — This 4-way inflation system was such a great addition to my compressed air system. So I am not using this system out in the field - I use it in the shop to inflate or deflate tires as needed on my vehicles and t…”
“5/5 — this is actually a pretty nice set up. If you’re in the market for a good, four tire inflate, deflate, and balance, this is going to do the trick for you. I bought this for my F150 and I can tell you that the ho…”

Fit and hose length
ALL-TOP designed the hose set as one-size-fits-most, covering vehicles up to a 200-inch wheelbase. The product data lists approximate fits: F150 (122–141" WB), Wrangler/Bronco 4-door (115–120" WB), and Tundra (145–165" WB).
Owner feedback backs that up. One F150 owner said the hose is "plenty long, with extra to spare" and noted it's a quality hose that isn't tough to roll up or kink. Another owner said it's long enough to fit both an Expedition Max and a crew cab Ram 1500.
Real-world use and owner notes
The system works with any powerful air compressor, and owners use it both on the trail and in the shop. One reviewer uses it in the shop to inflate or deflate tires as needed, calling it "a great addition to my compressed air system." Another says it's "a must have if you air down for trails."
One practical tip from an owner: you need to close the valve for the gauge to give accurate tire pressure, otherwise it can read a couple PSI higher than actual while running a portable compressor. The same owner likes that the kit includes covers for the chucks.
Warranty and support
ALL-TOP backs the 4 Way Inflation System with a 2-year / 24-month hassle-free warranty and lifetime customer support. The brand has been focused on overland products since 2015 and cites a 200,000+ offroad community.
