ULTRA4

The unlimited qualifying series for the toughest off-road one-day race on the planet.

THE ULTIMATE RACE ON THE ROCKS

A competition that spans endurance desert racing to competition-style rock crawls to short course racing.

Ultra4 vehicles are built to face the most grueling challenges in off-road racing, mixing all types of terrain and testing the reliability and resilience of competitors in day-long events. After adding numerous events across America over the years, the Ultra4 season continues to kick off with KOH, before splitting off into multiple regional series that reconvene for a national championship race in Reno.
