Ultra4-National-Championship-Off-Road-9-19-13CONGRESS, AZ: The 2013 ULTRA4 Nitto Tire National Championship race is back on at Thunder Rock Off Road Ranch in Congress, Arizona.

The race was originally cancelled in Las Vegas due to a permitting issue that caused two off road racing organizations, including ULTRA4, to cancel races the weekend of September 27th.  At the request of ULTRA4 drivers and their sponsors,  a suitable location was found for the same weekend at Thunder Rock Off Road Ranch in Congress, Arizona.
