New to Ultra4 USA racing? We made you a checklist.
Welcome to the most exciting off-road racing series in the country! Our racers tackle the toughest terrain and courses we can put together from East to West, all battling for hardware, prestige, and points to land on the final podium at Legends of the Fall at the end of the year. If you want in on the action, go through the checklist below. Contact us with any questions you may have, and we look forward to you joining our race family!




STEP 2
REGISTER YOUR RACE #
Every racer participating in an Ultra4 USA race must have a registered race car number through the KOH/Hammerking group. As KOH is the first race in our series each year, racers must comply with their numbering requirements. Click the link below to request a race number from King of the Hammers. You'll need your race number in order to purchase a USAC license as well as register to race. This link opens an email to make the request.
STEP 3
USAC LICENSE
Anyone racing with Ultra4 USA, planning to be in the hot pits supporting a racer (crew), or otherwise on course or near a race car in action (i.e. media), is required to have a USAC license as they are the sanctioning body of our race series. Click the link below to purchase your 2023 yearly license now (good for all races), or come back later and single-event licenses will be available as well. Note there are separate licenses for drivers and non-drivers.
STEP 4
RACE REGISTRATION
Once you have a race number & USAC license, you're ready to register to race! Click the link below to go through the process - and a reminder: there is a late fee for registering after Tuesday of race week (i.e. less than 5 days before the race), so make sure to get registered as soon as you can! Having a good idea of racer count helps us plan the details of each race.
