[2026 Upgraded] LASFIT H4 Tire Inflation Deflation System [No Leak & Kink] 200″ Wheelbase Universal Rapid High Flow Off Road Tire Deflator, 4 Tire Air Up Down to Inflate or Deflate at Once

Phenomenal performance!! I use it with an ARB twin compressor mounted in my Bronco and it works flawlessly!! The 2 hoses are easy to deploy and roll back up and they store easily in the bag it came with.

Well packaged and matches my Red 4Runner! One thing to note is that the digital reader takes two AAA batteries (not included). Works extremely well and very accurate. The PSI reading matches my TPMS readings inside the car. Has a solid quality feel in the hands. The quick disconnect ports all function nicely without that ‘loose’ feeling when handling. Even has a built-in backlight in case you need to use it in low light conditions. The metal part (manifold?) under the digital reader gets hot when in use. So remember to use gloves when handling! Used it one time so far and it makes the whole ‘airing up/down’ so much nicer without the guessing. One little touch of detail I love is that each port has a little rubber cover attached to prevent dirt getting into the hose. I got it bundled with their matching LasFit x4 dual air compressor. Comes with a 5 year warranty too! 🤩 10/10 would recommend.

I absolutely love this system, and will recommend it to everyone. The hoses are lay-flat rubber and the connectors are all solid. There's only one caveat that I can think of: it works fine with the average garage compressor that uses the standard compressor fittings you can get at places like Harbor Freight, Home Depot, etc, but if you plan on using it offroad and you have an air compressor like a Smittybilt 2871, then you'll likely need to get an adapter or see if "universal" connectors will fit. The offroad compressors such as the Smittybilt have an open, high flow design typically referred to as "Japanese" or Nitto fittings and they WILL NOT work with the "standard" fittings you get with garage compressors, even the high flow ones. I paired a male standard fitting with a female Nitto adapter ("CTA Tools 7043 Quick Coupler Adapter - Nitto" here on Amazon) and I now have an extra adapter that I can use when out on the trail and I need air. Some of these 4-tire inflation systems come with a Nitto adapter but this one did not and I didn't mind spending a few extra bucks to make the adapter for my own use. The other day the car my wife drives had low tire pressure so I drove out to her workplace, connected this system to all four tires (which automatically equalizes the pressure in the system across all the connected tires - just make sure that the slide valve on the system is set to closed), inflated the entire system to a safe minimum and then drove back home and it only took about 5 minutes to connect, inflate, disconnect, roll up the hoses, and pack it up in the bag.

Great item, does what it says it’s going to do. .

Works as desgined no complaints so far very impressed
