The Monster Valve Flat - KMC Edition (or MV-Flat, formerly MV4) packs incredible inflation and deflation speeds 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 40"x13.5"x17" tire from 35 psi down to 10 psi in under 30 sec. This kit also includes a Monster Chuck which, when used with a Power Tank, will inflate that same tire in 45 sec.
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 Tap, 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.
We worked directly with Alpha Equipt to ensure their xCommander Beadlock wheel is MV-Flat Compatible. Innov8 racing can also drill a Monster Valve
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.
Save 10% on a tire pressure gauge when you bundle with your monster valves! We recommend adding a Tire Pressure Gauge (TPG) 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. If you option your Monster Valves with a TPG, we'll include a free EVA Case! ($22 value)
Note: Fits only KMC Beadlocks with dual valve stems as standard. The KM444 is not compatible at the time of this writing.
