PowerTank Monster Valve Tire Deflator

Airing down is crucial for traction while on the trails. When you get to the trailhead, it can take quite some time to air down all 4-tires. This PowerTank Monster Valve Kit is the fastest tire deflation product available. This oversized heavy-duty valve stem is installed as a second stem into your wheel using a drill/tap (Sold separately). This allows you to air down from 35 to 10 psi in a 40x13.50" in as quick as 30-seconds! Easily installed in steel or aluminum wheels. Tires do not need to be unmounted & do not require re-balancing after installation. Due to the materials used this new valve stem is 5-times stiffer than a standard metal valve stem. Please note: Sold individually. Two are shown to better show the product.
