4 Tire Inflation System, 4 Tire Inflation Deflation System, 4 Tire Air Up Down System, 4 Tire Pressure Equalizer, Inflate or Deflate All 4 Tires at Once, Fits Up to 125" Wheelbase

It works as expected.

Works excellent on my new onboard air setup on my rock crawler.

It took some work to get this inflator to work for me. First off the push-on chucks would not work with my factory valve stems on my '05 4Runner. They'd clip on, but not seal, so it just blows air out. It was really simple to replace the chucks with others that I know work and have used for years.In replacing the chucks, I found the most restrictive part of this system: the crimped on 1/4npt hose ends. EDIT: That said, the schrader valves on tires is actually more restrictive that this passage. The average tire valve can only move 2cfm of air, and I doubt the hose ends constrict any less than that.EDIT (continued): I've had in very positive contact with with manufacturer and they are considering a change in chucks. The current push-on style is convenient, but don't always work

I chose the UHARBOUR kit for it being a little bit cheaper than Morrflate, and I'm thrilled with my decision. The kit is as described, came in a well-designed storage bag, making it easy to pack and unpack. The material of the bag seems to be tough and long-lasting. The "IM" quick connector fits my ARB air compressor perfectly, eliminating the need for additional adapters.I particularly appreciate the ability to disconnect any side for customized pressure settings of front and back, it won't air down unless the air chuck is connected AND valve is open. The airing up/down speed is really fast, going down from 40Psi to 20Psi took about 2 minutes, and aired back up in about 3 minutes, which beated the other guys in the group. It was really nice sitting in the car while watching them airing up theirs.In summary, the UHARBOUR 4 Tire Inflation System is a fantastic investment for off-road enthusiasts. Highly recommended!

The media could not be loaded. I cannot see a reason to purchase the more expensive sets.The hose rubber is flexible and doesn’t expand under pressure. Handles heat well, my compressor gets very hot. The fittings are good quality and easy to use. The gauge is very accurate, within 2 tenths.Great set very pleased so far.With the compressor in the video it only took less then 6 minutes to fill 35s from 15 to 40 psi.

If you trail and air down this is a must have.

I was super excited to get the Uharbour 4 Tire Inflation system. I have seen similar products at Jeep Jamborees and local off road parks. I recently had my tires rotated by a dealer when this arrived. I had to try it out as 34" tires are impacted more than smaller tires when the temperature change.There seems to be some leaks on the unit that I did not expect. I had to connect the pneumatic fitting to the pressure gauge and it included a roll of teflon tape. The leak was not from my fitting, but the other connections. When using this to try and get all four tires at the same pressure you need to act quick when done.I have started the process to return this item. The fittings leak.

Good quality, only issue it is not 100% air tight
