[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

Very happy with this purchase. This air compressor is super powerful. It’s well built. I live on the Texas Gulf Coast and we have plenty of legally accessible beaches to drive on. I’ve always dreaded to have to reinflate our tires. I have 35 in truck tires that need inflated at 65psi front and 70 rear. It only takes me less than 10mn to take it out of the truck, inflate all four tires to back in the truck. Something that used to take me over 45mn. I also like that you can preset the pressure so you don’t have to babysit the compressor for each tire. It also has an auto shutoff to cool it down and restarts by itself until desire pressure is achieved. It’s compact enough to fit perfectly on the side of the bed between the tailgate and the wheel well. Can’t think of anything bad to say about it. I eventually bought the 4 way extension and that’s made my life even easier. Just have to top off the rear ones for the extra 5psi. Weight wise, it’s not ultra light, but it’s very manageable to carry around with one hand. I’ve had to help someone with a completely flat spare tire for their car and it took what seemed barely 30s to inflate it. So a bit of an overkill for a car, but invaluable for a truck.

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.

LASFIT X4 Off Road Air Compressor has performed very well on several off road trips. Aired up 35's from 12 psi to 37 psi in under 3 minutes per tire. Recommended.

I have just used it for the first time yesterday at the end of our jeep run I also purchased a house system at the same time allowing you to connect all four tires at the same time and inflate them to the same pressure equally Well, I unraveled the hoses got them all connected to the tires open my hood found a flat spot to set the compressor hooked up the hoses turned on the compressor set the pressure to 34 and to my surprise it was very quick. The compressor kicked off a couple times and I thought oh that was quick but then after looking at the gauge on the hose set up, it was balancing it. Did this two or three times and finally it settled on 34 and both gauges agreed it only took a couple of minutes. Then one of the other club members was struggling with a little compressor he had he had 35 inch tires and when I hooked the gauge up to him, they were down to 18 psi. I brought the compressor over. We plugged it into the hose set up, turned it on And within a few minutes we were at 36 psi in his tires. The real surprise was, I had just stared up two vehicle tires ahead of the others who were just airing up their own tires. This compressor kicks butt I do have to say, though the manifold that you plug the compressor in with the gauge on it by the time you get to the end of the second set of tires, it’s so hot you don’t wanna hold onto it So I’m wondering if they have some sort of heat sink that they can attach to a keep people from burning their fingers but great products would highly recommend

I do not recommend it, it went bad after just a couple uses, it will not build air pressure past 60psi anymore , its useless for me now, and no answer from the “warranty department “ since weeks ago.

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.

Very strong, heavy, does get very hot if you do all four tires, but it is fast. The digital display is very hard to see in the sun, but 1st world problem there. It blows my massive Bronco Raptor tires from 25-40 lbs in about 15 secs per tire. Very reliable, sort of loud, but it includes the gloves you will need to wear. Comes with generous extension cord and ease of use is simple. You can blow up 4 tires in about 2-3 min. With that said, the compressor is uber hot by the 4th tire. WEAR THE GLOVES and await the compressor to cool down before throwing back into the car/case. Very nice, would buy again, but heavy and takes up quite a bit of space in the truck.....as would be expected.

This compressor works great. I use it with the lasfit four tire system for inflating my tires after airing down for four wheeling. It airs all four tires up from 20 PSI to 35PSI in less than five minutes. Better than expected!
