ALL-TOP 4 Tire Inflation & Deflation System, Up to 200" Wheelbase, Rapid High-Flow Air Up Down Kit w/Digital Pressure Gauge & Worry-Free Quick Fitting Package

Quick, simple, and well made.Would highly recommend.2019 Jeep Wrangler on 37's with onboard air compressor...all 4 tires from 18psi to 36psi in less than 5 mins. Equal pressure to each tire.Great buy.

Worked perfectly for my needs and reached all 4 Bronco Raptor tires easily.

I love this product. Note that in order to deflate the tires you can’t have the adapter for the compressor screwed in to the gauge. Just attach the four tubes to the tires and the gauge itself will allow deflation by moving the piece up and down. Then, to inflate, attach the appropriate connector to the gauge and connect that to the compressor and inflate.

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 this system allows me to quickly dial in exact PSI and make sure that each tire matches and is even. The system is well built and definitely priced appropriately.Keep in mind that it will not allow you to read PSI on individual tires - just on all four as a whole, which is the point - I wanted them all equal. The hoses are long enough and great quality. Depending upon the capabilities of your air compressor - you can either do two tires at a time or all four at a time. The head unit will require 2 "AAA" batteries which do not come with the product. I have seen several of these types of systems on the market - I'm very happy with this choice, I would recommend.My grading scale:5 Stars = Knocks it out of the park, PERFECT BUY!4 Stars = Excellent find, you should definitely give it a shot.3 Stars = It works and functions as advertised.2 Stars = A little scary, but do your research and it may work out.1 Stars = Avoid this product and look elsewhere.All of my reviews are based on actual use of the product. I do not communicate with sellers and I am not compensated for positive or negative reviews - they are as honest as I can make them.

Amazing product. Works well and efficient. I have 37” tires and it fills them up easily. Quick tire reinfecting after off roading

Love this. It’s long enough to fit both my expedition max and crew cab ram 1500. You do need to close the valve for the gauge to give you accurate tire pressure and not a couple psi higher than actual while running a portable compressor.This ensures that all tires will have the same pressure. It does take a minute to roll everything back up.I didn’t read it in the item description anywhere but the gauge is auto turn on/off.

Works good

Battery area came all rusty looking. Seems really cheap
