We have made changes and upgrades to every component on the original Power Tank to get super fast tire inflation speeds. The only thing we couldn't upgrade was your stock valve stem. Until now.
Monster Valves are an oversized secondary valve stem you install in your wheels. They make the fastest tire inflation system on the market even faster. Imagine airing down a 40 x 13.50 x 17 tire down 15 PSI in 17 seconds. This kit also includes a Monster Chuck which, when used with a Power Tank, will inflate that same tire in the same amount of time.
We machine our Monster Valves out of 7075 aluminum to be extremely tough and they are so light that your tires don't need rebalancing after install. If you have bigger tires, Monster Valves are essential trail equipment.
The Monster Valves requires drilling and tapping a 7/16 hole in your rim and does not necessitate tire removal for install. We include a bright steel tap when you buy a set of four or five valves to clean installs.
