Diesel Mafia’s race truck is honestly one of a kind. 🤯🔥

Seeing this truck in person at UCC completely blew our minds. The attention to detail, the craftsmanship, and the performance packed into this build are on another level. It takes a lot to impress our team, but this truck did exactly that.

Huge shoutout to the crew at Diesel Mafia for bringing one of the wildest builds at the entire event. If you got the chance to see it at Ultimate Callout Challenge, you know exactly what we’re talking about. 🔥💨

Don’t be this guy. 😬

The factory grid heater bolt on a 6.7 Cummins truck is a known failure point. When that bolt breaks loose, it can get sucked directly into the engine, causing severe damage to pistons, valves, cylinder heads, and even the turbo. What starts as a small hardware failure can quickly turn into a complete engine replacement.

A grid heater delete removes this weak point and helps protect your truck while improving airflow into the engine.

If you’re driving a 6.7 Cummins and haven’t addressed your grid heater yet, now is the time.

There were some insane burnouts all weekend at UCC, and a few definitely stood out from the rest. 👀

Who do you think had the best burnout?👀
