🔥 A Decade of Diesel Dominance. A Legacy That Keeps Growing. 🔥

Since 2016, the Ultimate Callout Challenge has been the proving ground for diesel performance excellence. From Lavon Miller’s three-peat dynasty and Derek Rose’s long-awaited championship, to the rise of Justin Zeigler, Tony Burkhard, and Kenny Bruner, UCC has become the ultimate showcase of innovation, grit, and horsepower. Each year, new records are set, new heroes rise, and the diesel world witnesses the relentless evolution of power at its absolute finest.

🔥 The Pinnacle of Diesel Competition. The Best of the Best. 🔥

The 2026 Ultimate Callout Challenge (UCC) isn’t just another event — it’s the crown jewel of diesel performance, a battlefield where only the elite compete.

At the heart of UCC is something truly unique:
➡️ An Invitation-Only Competition, where the top competitors from across North America are handpicked to face off in an extreme three-day test of power, endurance, and engineering mastery.

These aren’t just racers — they’re builders, innovators, and champions — and they’re bringing the absolute best that diesel technology has to offer.

The UCC Challenge:

• 🏁 Friday: Drag Racing — Diesel monsters tearing down the quarter-mile, where precision tuning meets raw, ground-pounding horsepower.

• 🚜 Sunday: Sled Pulls — Old-school grit meets cutting-edge engineering as these trucks hook to the sled and fight for every inch.

Only the strongest survive. Only the most complete team claims the crown.
