April 20th-23rd: Anniversary Bash, Rush Off-Road
presented by RACELINE WHEELS


Ultra4 USA heads to the mountains of Kentucky for the first East race of the 2023 season. This woods course will challenge racers with varied and sometimes unpredictable terrain. This event is a treat for spectators, as America Pro Rock Racing puts on a show you won't want to miss Saturday night. Rock bouncers and UTVs will run knockout hill climb races as well as a bounty hill, a display of horsepower and force that is exciting to watch.


Tickets & camping arrangements can be made directly with Rush Off-Road for this event. Click the button below to go to their website for more information.
