NEW! Now includes TPMS sensor adaptor brackets! If you don't want to include TPMS sensors, simply remove the bracket from your Flat2s when installing, and set them aside in case you decide to add them later!

NEW! Red air-down collar has been re-engineered to be more ergonomic and easier to use.

Limited Time Exclusive! TPG RED modular Tire Pressure Gauges available now ONLY when bundled with a Monster Valve™ 5 pack!

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 STILL 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 40 sec. Air up with your Monster Chuck (included) directly on your Ventoso RED modular tire inflator gauge!

These Monster Valve™ 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 with a simple nut and washer. 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. 

Other companies with dual valve stem wheels include:

• Innov8 Racing - upon request
• Alpha Equipt XCommander
• Trail Ready - upon request

With an all-aluminum construction the total weight of each valve is a mere 1.1 oz. and does not require a tire rebalancing. Due to its construction, it is 5 times stiffer than a standard metal valve. We've seen a wheel deflect off a boulder on the trail without damaging the wheel or Monster Valve™. 

Because the Monster Valve™ is a secondary valve stem, you retain your TPMS sensors on your OEM valve stems. 

Note: Fits only KMC Beadlocks with dual valve stems as standard. The KM444 Mesa Forged does not work at the time of this writing. When installing in a KM236 Tank, rotate the beadlock ring to increase clearance for the Monster Chuck. We have not tested all models and fitments and some material may need to be taken out of the beadlock ring for Monster Chuck access such as on the KM237 Riot with -12 offset. Wheel compatibility with your specific model and fitment IS NOT GUARANTEED. 

Because of the incredible speed, we HIGHLY recommend a large, easy to read Tire Pressure Gauge on your Schrader Valve. 

The NEW Ventoso™ RED Tire Inflator Gauge and TPG RED Tire Pressure Gauge come standard with swappable chucks. Limited time exclusive optional add-on to any Monster Valve™ 5 pack kit.

The Ventoso™ RED is available in five gauge options and will come with both a HiPPO2 Schrader tire chuck AND a modified Monster Chuck without the ball valve for inflating directly with your Tire Inflator Gauge.

The TPG RED is available in five gauge options and will come with a HiPPO2 Schrader tire chuck to attach to your Schrader valve stem to monitor second-to-second tire pressure as you air down with the Monster Valve™ and air up with the standard Monster Chuck attached directly to your air source.
