The Monster Valve Wedge (or MV-Wedge, formerly MV3) 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.

Note: All Monster Chucks are now standard with a 45° elbow rather than the 90° elbow pictured.

They are easy to install into steel or aluminum wheels. Just drill a 1/2" hole and tighten them from the back using the Monster Key included with every four or five pack kit. Unlike the Monster Valve 1, these can not be installed with the tire mounted but, because you do not need to tap 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.

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

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.

User note: When finished airing down, screw the red collar down until air flow stops or screw down fully and back out 1/8-1/4 rotation to properly seat the o-ring and prevent leaks.
