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

The Monster Valve™ Primary - MV-P is the latest entrant in making Monster Valves™ easier to install and fit a larger variety of wheels. This can be run in a standard valve stem hole and works as you Primary and only valve stem! No modifying 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. 

These Monster Valves™ fit in most standard valve stem holes using a 30 degree bracket and an optional spacer for recessed valve stem holes. They are secured on the back with a nut and washer and sealed with a rubber grommet. A TPMS bracket is included and can be used to retain your factory TPMS sensors or add aftermarket TPMS sensors. 

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™. 

The included TPMS bracket allows you to reuse your factory or aftermarket TPMS sensors. 

Japanese vehicles may have TPMS incompatibility. We recommend this aftermarket TPMS sensor.

The included Monster Chuck only works in Power Tank Tire Inflator Gauges with a RED Quick-Switch Coupler. You can purchase your Monster Valve™ Primaries with a new Ventoso™ RED Tire Inflator Gauge, upgrade any generation Power Tank Tire Inflator Gauge with the RED Upgrade Kit, or skip the Ventoso™ RED Tire Inflator if you already have a RED Quick-Switch Coupler on your Tire Inflator Gauge. Previous generation Switch-Hitter and Big Kahuna models are Monster Valve™ Primary compatible.

Note: While we based the angle bracket on typical valve stem fitment, there is no standard to follow and we can not guarantee fitment in your wheel. Recessed valve stem holes, bead lock rings, faux lock rings, and certain wheel designs can all cause interference issues. Wheel compatibility with your specific wheel model and fitment IS NOT GUARANTEED.
