Outran 4 Tire Inflation Deflation System,Air Up Down Kit with 300psi Digital Tyre Pressure Gauge Closed Flow Air Chuck 4 Tire Inflator for Truck, Car, Trailers & Motorcycles

This is a great item at a great price, which is why I feel compelled to leave a review. For its very modest cost versus the greater than 2-times price difference with its competition, I was expecting a lesser product. This was a very good surprise! I used it with my All-Top Dual Cylinder automatic compressor and it worked quite well. There is a mistake in the description: the hoses are 1/4”, not 3/8”, which is a 50/50 result. The 3/8” hoses would air up faster with lower heat build up at the compressor, BUT the hoses would take up much more space in my overloaded cargo area.The hybrid hoses are definitely the right choice, and the lengths were more than ample to reach from the engine compartment to all 4 tires on a Sprinter 2500 (shorter version). I was able to inflate all 4 tires from 18psi to 45psi in just under 2 minutes, and then I disconnected the hoses/chucks to the lower pressure tires (front) and continued to fill the rear tires to 76psi. The clamp-on chucks only flow air when they are clamped on. The chucks themselves are solid brass, are heavy duty-sized, and the clamp mechanisms are robust. I expect them to last.The manifold is a solid, quality part that will also have a long life. The digital gauge registered the exact same pressures as my handheld digital ARB gauge and also appears to be another robust item in the kit. The manifold has a ball valve for shutting off the air flow when it comes time to walk around and disconnecting the chucks. At first I could not shut off the gauge’s digital display via the on/off button, but realized that I had forgotten to release the manifold pressure by opening the ball valve, and once that was released, the gauge could be shut off as expected. The only light duty component is the carry bag, but for the price of the whole kit I am happy to spend $20 for the exact bag I want. Pleased with this purchase!

Works great!! I'm impressed with this set up. I tried it out on my wife's '14 Jeep JKU in the driveway. I used Bolder Tools tire deflators to deflate the tires. I think it's way easier and faster to use deflators instead of unrolling the 4 Tire Inflator to deflate. In 4 to 5 minutes the tires are flat at 10lbs. Boulder deflators work great. On sale for $16.99 down from $36 (Boulder Tools Tire Deflator - 80 PSI Air Pressure Gauge - Adjustable, Automatic for Cars, Trucks and Motorcycles - Ideal Offroading Accessories) After the tires were flat I pulled the 4 Tire kit out. There are no directions but easy enough to figure out what to do. No leaks in valve connections. The gauge is accurate. Inflated tires to 32lbs per supplied gauge. Checked with my other gauge and it was 32lbs. One review said the gauge does not shut off. It will turn off after 3 1/2 minutes. I timed it. No need to remove the batteries. It took about 7 minutes to inflate 4 tires from 10lbs to 32lbs using a Maddox 12V 125PSI High Performance Inflator from Harbor Freight. This will speed up airing up 2 Jeep JKU's after the Dunes and the Trails. The hoses come packed with plastic strips wrapped around for shipping. I cut some pieces of velcro to secure the hoses in the bag. I recommend this product for inflating after you are off the dunes and trails.

Works well

Easy to use but you have to have a large air compressor if you are impatient. Take your time with the valve stem locks and they work fine. Storing the air lines is a bit cumbersome. Only dislike is gauge immediately turns on upon battery insertion and does not turn off until battery removal. However, gauge shows basically same pressure as two other gauges I compared it to. It is a keeper for $120.

Everything worked great, and price point is better than some of the “brand names” in the off-road industry. I hope it lasts!

Works very well. Quality seems high. The schrader valve connectors feel very high quality and easily connect and disconnect with zero air loss. I'm OCD and like seeing my car's TPMS show the same PSI on all four tires so this helps a lot with that.

Purchased the kit for my 16' Jeep Wrangler JKU. I've only tried it out in my drive way but was able to equalize the pressure on all four tires, deflate all four, and then inflate all four. The manifold and pressure gauge connected directly to my ARB Compressor. To get the correct pressure reading you need to close the valve on the manifold. It takes some practice but it makes airing up and down very easy and all four tires end up with the same pressure when you're done. I had to change out the chucks to fit the valve stems on my headlocks but the kits comes with standard sizes that make it easy to swap out parts to fit your needs.

works fine however used it for the 1st time today and one of the air chucks came missing the pin that locks it to the valve stem when clipped on. Aside from that works well.
