MIKKUPPA 4 Tire Inflation System - 4 Tire Inflation Deflation System, Tire Pressure Equalizer with Quick Coupler Adaptor Closed Flow Air Chuck for Car Trucks Off Road Vehicles Up to 195" Wheelbase

It’s new to us and we have only used it 4 times now out on the trails but for airing up and airing down it works flawlessly. For the money spent keeping our 35” Toyo open country rt trails perfectly matched and quickly it’s a great value. I would buy again or recommend to a friend. Hopefully it holds up long term. The quick connect attachments never leak (knock on wood)!

I love this! I own(ed) a 3X locked 80 series Land Cruiser (it recently got stolen) and took it out for the whole month of September out west to Colorado, Utah, etc. The remote places I went to necessitated airing down/up, making it a breeze. I tested the accuracy of the gauge and it was spot on. The quality is very good and the quick air chucks are perfect. I will be getting another one because mine was in the Land Cruiser when it was stolen. I paired this up with the Thor's Lightning dual compressor.

I got this to equalize and/or pump up the air pressure in my 4x4 tires. I truly appreciate the same PSI in all tires and this makes it easy. The valve stem attachments are easy to use, the rubber hose is flexible and easy to use, the cutoff valve works well. The bag it ships in seems compact enough but getting all the hose back into the bag after you use it for the first time is challenging but doable. You will need to determine how you will connect this to your preferred air compressor. I already had an existing 12v portable air compressor and I purchased a separate adapter from another Amazon seller that connects into the hub (using the same style connector) and allows my portable 12v air compressor output hose to screw on to the adapter (it looks like a tire valve end). Overall, very pleased with what you get for the price.

Only one coupler worked well and the rest were either super leaky i couldn't fill with. And the last one didn't even grab on the valve right and no air was getting in or out the tire.

Perfect for inflating all four tires after trails. Can make sure all are at the same pressure. I matched it with my ARB and it's all I need.

This has been great for cutting down on the time airing up and down. Only 4 stars because the gauge is off by 2 psi and the couplers that attach to the valve stems are not the greatest quality, you need to spray them with lubricant often to get them to operate well.

So here is the skinny on this kit. I have loved it so far. I have used it to air down my jeep 4 or 5 times now and have had zero leakage issues with the vales or the connections. I even took it to work as I am a tech for a dealership and used it to air down new car tires for delivery and found the gauge is about 2 lbs off after checking it to the cars TPMS. (Hence the 4 start accuracy rating). For the money you cant go wrong with this kit!!!

This inflation / deflation system has all the right components. The hoses are flexible and easy to roll up. The digital gauge is accurate and has a nice backlight readout which is easy to read in the dark. I saved at least $60 and I don't see where I sacrificed any quality or convenience. I love this system and use it on my jeep every weekend to air up and air down.
