The MASSFX Pit Viper wheels are some of meanest wheels you can throw on an ATV/UTV. They were designed to strike fear into any obstacle or opponent they come across. The Pit Vipers are constructed from aluminum, which allows them to be lightweight and also extremely strong. The “snake tongue” spokes also add to their rigidity. Their stylish design compliments the tire as well as whatever vehicle you put them on. These wheels have a 12×7 with a 4/156 bolt pattern (most common among Polaris RZRs) and come in a Black finish. Be sure to check out the Gun Metal wheels as well! Start “Doing Fun Right” with MASSFX!
