Up Down Air 4 Tire Inflation System - Jeep Wrangler JK & JKU Engine Bay Mount Driver Side Rear

Like the product, had it Professionally installed. The only thing I can't get to work correctly is the gauge tells me the tire is at 32psi and when I check the tires they'll all be off by 8psi.

Great item after installing not sure worth the money for what it is but it does work as it says would recommend to someone if price was slightly lower

UPDATE: After some real practical use of this system and trying to “fix” it and trying different or simpler methods, I have concluded that this system is worthless. The valves don’t allow enough air through, the lines are undersized, and the valves don’t seem to connect reliably to both the tire and the valves that are installed with the system. You would be better just building a T with 2 long lines & work 2 tires at a time. I bought a 1-3 adapter and added 2 long lines, added a pressure gauge and it works better.Great idea, poor execution on the Betty valves. The jumpers that tie the system together use convenient Betty valves for quick attachment & release on the valve stems. The problem is the internal design of these valves is extremely restrictive to air flow - which is the entire purpose and function of the system. Because of these poor flow valves, it takes WAY TOO LONG to actually air up or down. Worse is they don’t flow at the same rate. Some are slower than others and takes up to 20 minutes (after you think it’s done) to actually stabilize and equalize the pressure on all 4 tires. I replaced these poorly constructed valves with another type that allows better air flow. Now it works! But, the customer should not have to redesign and rebuild what should be a properly engineered system. At that rate, I could just build my own from scratch for cheaper & it would have worked more efficiently from the start.Only giving it 2 stars due to this fundamental failure in product quality review. I don’t think the manufacturer actually uses and tests it’s final retail product on their own vehicles to ensure its practical designed use is properly functioning.
