Monster Valve 4- KMC Edition Rapid Tire Air Up and Air Down Kit
incredible inflation and deflation speeds of the previous Monster Valve versions with a foolproof install process. Monster Valves are over sized, light-weight, yet strong valve stems that you install as a second stem to your wheel. Made from 7018 aluminum, they are the fastest tire deflation and inflation product on the market.
Imagine airing down a 40x13.50x17 tire from 35 psi down to 10 psi in under 30 seconds. This kit also includes a Monster Chuck which, when used with a , will inflate that same tire in 45 seconds.
These Monster Valves have been engineered with KMC Beadlocks with dual valve stems in mind. They simply drop into one of the stock holes and the rubber grommet is tightened from the back using the included Monster Key.
There are no modifications to the wheel. Unlike the Monster Valve 1, these can not be installed with the tire mounted but, because you do not need to tap or drill into your wheel, the install is much easier.
With an all aluminum construction the total weight of each valve is a mere 1.6 oz and does not require a tire rebalancing. Due to its construction, it is 5 times stiffer than a standard metal valve.
We recommend adding a tire pressure gauge with a large, easy to read face to get accurate readings while you're airing up and down. You'll thank yourself when you see how quickly the pressure drops.
