4 Tire Inflation Deflation System, 4 Tire Air Up Down System, 4 Tire Pressure Equalizer, Inflate or Deflate All 4 Tires at Once, Flexible Air Hose Fits Up to 155" Wheelbase.

Arrived safely. Nice bag although it will probably be hard to put back in it. Haven't used it yet but if it leaks I'll just add Teflon tape that comes with the kit. Don't see any failures to exist. Would recommend

Works exactly as anticipated, I was going to make my own and once I started to add up the cost of the parts, it became clear that purchasing would be wiser. I tested it out, works great for both deflating and inflating. This will be living in the truck from here out.

Super easy to use. Glad for the different chucks. The bigger ones wouldn’t work with my rims, but the smaller ones worked fine.

Higher quality than expected equal to others costing 30-100% more. Came with 4 alternate style spare air chucks and a female QD for the compressor as a bonus.

I recently installed an onboard air setup on my Jeep, which means I have a 7 liter air tank and a continuous duty cycle compressor an order to keep about 140 PSI at all times.With this kit, I can hook up to the quarter inch air outline that I have, and use this to fill up all four tires in one go and it ends up being quicker and more efficient, while also catching eyes. What I really like about having this setup is by airing up all four tires at the same time off the same line, you can equalize pressure across all of them and you don't have to run around and check each tires pressures and add or remove air to equalize them.

If you play with your tire pressure when you hit the trails, one of these is a must have.Hook it all up, and release pressure evenly.Then when you're back, you don't have to go around the truck with the compressor one by one. Just hook them all up and let the compressor go to town on them all at once.Really you can't NOT get equal pressure to all corners.

I have always considered making up my own 4-tire setup to get equal pressure in all 4 tires. I HATE the time spent trying to accomplish that while checking and airing up or down each tire. I sometimes think the tiny bit of difference in one is the result of the air used in the gauge. A pound or two hi or lo in all four isn't so much a problem for me as is a pound from one to the next.This set is perfect for obtaining equal pressure in all four tires and all I had to do was order it and hook it up. I now have even pressure in the tires of my car, truck, and even yard wagon. It is particularly helpful with the wagon as I lose pressure over time in one in particular and the others occasionally. When one is low now I simply hook up all four to air them up.For a pro shop getting things precise could be a business selling point. I always hate checking my tires after installation and finding out they didn't air them equally.For offroad enthusiasts you know the importance of different tire pressure for different conditions. Rock crawling, mud, sand, etc. One tire with the wrong pressure can mean the difference between getting stuck in the middle or finishing at the top of your game.Great product. Great value.

The media could not be loaded. If you are like me, you don’t enjoy the idea of putting air into all the family vehicle tires, going to each one, checking the pressure, and then adding and removing air to get each one to the correct tire pressure. This little device can make it easier.Basically you have one hose with four different sections leading from the air pump to the four wheels of the vehicle. Since the connectors are a closed design, you can actually do any combination from one to four wheels, and it will work just fine. As you connect the tires to the hoses, you will hear a small air sound as the tires try to equalize pressure between them. Once all are connected, the pressure gauge near the pump, which is battery-operated and included, will show the pressure of the tires. Pay attention to the instructions on how to move the valve and when to start the pump; otherwise, some pumps can be damaged by overpressure. Run the pump until you have the tires all at the correct pressure and then shut down the pump, close the valve and let the gauge settle for a time to make sure the tire pressures are set. If the pressures are too high, a small valve will release some air from all the tires.When you are finished you can actually get the set back into the bag by taking off the hoses and wrapping the Velcro around the wrapped hoses. This is a big bonus to me since most items like this never fit back into the bag they come inside.This is a fantastic system for quickly and easily inflating or deflating multiple tires to the exact same pressure. It seems well made and designed. I could not be happier with the system.
