2015 RANCHO CORDOVA, CA : A record-breaking 115 drivers took part in the 2015 MetalCloak Stampede held at the Prairie City SVRA park outside of Sacramento. With thousands of fans present for a full day of racing, the event was the largest to date for ULRA4 Racing at the park in both car count and spectator turnout. For the first time in ULTRA4 history, the limited and UTV classes outnumbered the unlimited 4400 class at the MetalCloak Stampede. The largest limited classes were the 4500 modified class and the 4800 legends class. The 4500s and the 4600 stock class raced together as did the 4700 spec cars and the 4800 legends cars and the UTV Sportsman and Pros also raced together.
Hammerking has established a racing class known as the ULTRA4 class. The defining characteristic of this class is that all cars must be capable of 4-wheel drive. Beyond that, the class is unlimited. These cars come in all shapes and sizes and are capable of speeds over 100+ MPH and still contain gear ratios as low as 100 to 1 for technical rock crawling.
