Power Tank Monster Valve Kit - Monster Valves

You may think your standard valve stems are good enough for your wheels-until you see a Monster Valve in action. We drilled a set into a pair of Walker Evans beadlock wheels and, instead of drilling out the preexisting valve stem hole, we left the standard valve stem and drilled a new hole for the Monster Valve. Why? The Monster Valves have a much larger body than standard inflation chucks, so pressure gauges will not fit. Leaving the standard valve stem allows you to still fill your tires up at a gas station if you don't have access to an air source and your Monster Valve inflation chuck.   |   power Tank Monster Valve Kit air Chuck And Valves How fast do these work? We were able to deflate a 42-inch tire from 22 psi to 10 psi in 13 seconds. We were also able to fill a 42-inch tire from 0 psi to 22 psi in 22 seconds with a standard air source and the Monster Valve inflation chuck. Next time this truck goes out to the sand dunes, it will be much nicer to air down the tires and get out there in a hurry!
