Austin Denny: The Relentless Heart of Denny Family Racing

Forged in Fire, Fueled by Family, Ready for UCC 2025

In the world of diesel competition, heart often matters as much as horsepower — and Austin Denny is bringing both to the 2025 Ultimate Callout Challenge.

Representing Denny Family Racing with pride, passion, and perseverance, Austin is setting out to prove that when dedication meets engineering, greatness follows.

The Build: All-In on Power, Precision, and Passion

At the center of Austin’s campaign is a machine built for serious battle — a 2006 F250 6.0 Powerstroke transformed into a full-fledged competition rig:

• WDI 500/400 Injectors — Delivering monster fueling with competition-grade precision.
• WDI-Built Long Block — Forged for durability, tuned for power.
• Flatout Diesel 4R100 Transmission — Transmission toughness ready to survive the worst UCC can throw at it.
• SoCal Billet Compound Turbo Kit — Featuring 80mm and 94mm Bullseye Power NLX ball-bearing turbos, breathing fire into every launch.
• 25.6 Chassis Certification — Crafted by Nathaniel DeLong for serious safety and serious speed.
• Custom 9" Axles — Hand-built by Austin Doidge, giving Austin’s truck brutal strength and race-ready reliability.

Every piece, every weld, every part of this build carries the signature of a team willing to put it all on the line.

The Crew Behind the Wheel

No champion stands alone — and Austin Denny is backed by a loyal, hard-hitting team:

• Alex Mahr
• Shane Cave
• Kyle Bernard
• Austin Engleking
• Warren Long

Together, these friends and family members form the backbone of Denny Family Racing — a crew that brings not just skills, but heart and belief to every run down the track and every pull across the dirt.

Lessons from 2024: Fueling the Fire

Austin’s 2024 UCC run was a year of challenges — a hard-fought weekend that didn’t show the full potential of the build.

Mechanical battles and tough event conditions kept him from posting the numbers he knew the truck had inside it.

But true competitors aren’t judged by easy weekends — they’re judged by how they come back stronger.

And Austin Denny is coming back with a vengeance for UCC 2025 — armed with experience, refined power, and an unstoppable drive to prove what he and his team are truly capable of.

The Spirit of Denny Family Racing

In a world where big-dollar teams often dominate the conversation, Austin Denny’s story is a powerful reminder of what diesel competition is really about:

• Building with your own hands.
• Fighting through setbacks.
• Celebrating every late night, every wrench turn, every breakthrough — together.

With sponsors like Warren Diesel Injection, Bullseye Power Turbos, SoCal Billet Inc, Hot Shot’s Secret, Flatout Diesel, and Cave Iron and Metal Works standing behind him, Austin Denny is ready to light up the UCC battlefield once again.

Ready to Write the Next Chapter

UCC 2025 won’t just be another event for Austin Denny — it will be a chance to showcase everything he, his team, and his family have built together.
