I was impressed until my buddy used his ARB onboard system to air up 8 tires before I had air in 3. All four jeeps had 33 inch tires - one had 10.5 and the others 12.5 width. Took 30 minutes. Air up was from 12 to 30 psi. Not worth my money.

Avoid this kit!!
Nothing good about this mess. Compressor isn't dust or waterproof, must be mounted upright, isn't 100% duty cycle. Tank is only designed to be mounted upright so very limited installation locations. Requires you to buy extra parts for installation. After 3 days I still haven't tracked down all the air leaks from the cheap parts used in this kit. I do NOT recomend this kit at all.

On Board Air is the only way to go for quick changes in tire pressure to deal with mud and snow. The system is 100% complete out of the box no need to buy additional parts,Installed correctly I find there is no more than 10lbs "leak down" in a 24 hr period. The pressure recovery is fast, quiet and automatic so there is no drain on the battery when left on 24 7.It also has an option to mount your air filter remotely for quick change replacement of filters and prime location. I have used many systems over the years and this is the best by far. The only thing I would consider is upgrading the air lines if you are in cold weather climate.

Good Ounboard Air System
I love this on board Air System, easy to use, the only problem is the installation if you want to do it right you need to run many air and electric lines.
