What: Monster ValvesUsing It: Installation seems daunting at first, but it's not bad. You drill and tap a hole, then screw in the Monster Valve, using some quality pipe dope or at least four wraps of Teflon tape. Once installed, the Monster Valve looks like an ordinary valve stem, only jumbo-sized. We tested ours with the company's Monster Valve kit (PN MON-8200) with the Monster Chuck for fast filling. We also tested the company's Monster Ready Tire Inflator Gauge (TIG, PN 8211) that can be used with the included hands-free chuck for standard valve stems or with the Monster Chuck. Once installed, to deflate you can either unscrew the Monster Valve core just like a normal valve stem, or you can unscrew the red anodized knob to open the bleed ports, allowing quick deflation without the risk of loosing the valve core. We tried it both ways and found the bleed ports every bit as blazing fast as removing the valve core. To inflate with the optional TIG, close the valve to seal the bleed ports and fill with your compressor or Powertank hooked to the Monster Chuck. It's fast-really fast. After using the Monster Valves, we'd almost consider them mandatory for 40s or larger tires.Highs: Very high-quality components; sturdy, solid feel; incredibly fast deflation and inflation ratesLows: Installation a little scary for some; so fast they really need use of dial-type gauge hooked to stock valve stem to prevent over deflation/inflationPrice: $130 (set of 4 with Monster Chuck); $70 (TIG-60 gauge w/ standard chuck); Total as tested: $200Get It: Advanced Air Systems, 209/366-2163,
