Works great
Everything seems quality, the quick connects seal first try, I’ve had it all up to 80psi and no issues. The T is much better than having to fill each bag individually.

Air
Everything works and seems to be pretty good quality, especially for the price. It doesn't hold air 100%. But it does last more than a day.

Great deal, worked perfectly
Everything was as advertised. There were plenty of parts to use as optional mounting configurations. Quality was good price was great, shipping was fast. I installed airbags on my E350 tow van, just towed my toyhauler 150 miles and everything did great. Very pleased, definitely recommend 👌!!!

Contains Every Thing You Might Need
I purchased this kit to help me solve an air leak problem I was having with a new Air-Lift kit I purchased for my 2025 Silverado. I have used Air-Lift systems for year's with no problems. The latest install I was not so lucky the new Air-Lift kit contained air hose and fittings that were minimal at best. The hose was short and there were only two fittings, the elbows for the top of the bags. I found a leak in one bag and one elbow fitting, both were replaced under warranty, only to find out I still had a leak. Nothing left but hose? I order this kit and with the fittings it allowed me to test the system in sections and locate the leak in the lines. I had enough hose and fittings to install the system with a manual fill option, and no leaks.

Le kit est parfait, mais le tuyau est beaucoup trop rigide, beaucoup de misère à la déplier, mais ça fait la job
