Hey everyone, just a heads up.
Ultimate Callout Challenge is only 2 weeks away, and with 2 of our trucks getting ready to compete, our schedule will look a little different over the next few weeks.
• May 18th–22nd: Last week of normal full operations
• May 25th–29th: Very limited shop operations as we focus on final prep for UCC
• June 1st–8th: Shop closed while we’re getting loaded and away competing at UCC
• June 9th: Back to normal full operations

We truly appreciate your patience during this time. We’re doing our best to continue taking care of our customers while also pushing hard to get these builds ready to represent at UCC.

This is a huge opportunity for us, and we’re excited to bring you all along for the ride.

For those that don’t know, we’re gearing up for Ultimate Callout Challenge with TWO trucks this year…
One in UCC, and one in 72 Fast.

Right now, all of our time, focus, and late nights are going into getting both trucks ready to compete.

Because of that, I want to give everyone a heads up:
If responses are a little slower, or if your truck, parts order, email, or text takes longer than usual… you are NOT being ignored.

We’re still here. We’re still working. Just juggling customer work while pushing hard to show up and represent at a high level.

We appreciate the patience more than you know. None of this happens without you guys.

After UCC, it’s right back to full speed.
Let’s go 💪🏼

Fabrication & safety equipment are just about wrapped up. Huge progress being made!

If you’ve ever had a 6.7 Powerstroke pop a cold side pipe and leave you on the side of the road… you already understand this one.
