Unleashing the beast: The Summit USMTS National Championship presented by RacinDirt is the ultimate proving ground where only the fiercest, most skilled dirt slingers in North America dare to tread. This is where legends are forged, battles are won and the roar of engines drowns out the weak.

Back in 1998, Todd and Janet Staley took a raw, untamed beast called the United States Modified Series and unleashed it on the world as the USMTS. Since 1999, this juggernaut has been tearing up the tracks while dishing out over $20 million in hard-earned cash to more than 4,700 warriors across 185 battlefields in 19 states.

This is where the elite meet, and every driver from the top guns to the local heroes, get a shot at glory. Over 1,500 gladiators from 36 states have thrown down at 58 of America's most brutal dirt tracks, turning each event into a spectacle of speed, skill and sheer audacity.

As we charge into the 27th season in 2025, get ready for 22 of the toughest, grittiest arenas in the land to host 39 nights of relentless, heart-pounding action. This is where the real racers of dirt modified racing come to show their mettle. Are you ready to witness the chaos, the speed, the glory? This is where legends are made, the dirt flies and the engines roar. Get ready for the USMTS—where only the toughest survive.
