Only 13 years old and already rolling on a fully loaded steel-body with JTXS on it. More importantly, he’s earned it. He’s always willing to lend a hand and help the team wherever it’s needed. The work ethic, dedication, and attitude dosent go unnoticed. This is just the beginning 🔥

The finishing touches are coming together on this truck. 🔥 We just got these stunning KG1 26x14 Elixirs wrapped in massive Fury MT2 405/30/26s, and they completely transformed the look of this build.
We’re officially in the final stretch. Just a couple more days of dialing everything in, and this bad boy will be ready for pickup. 💪🏾

This customer decided it was time to wake up his Ram dually. 🔥 We turned up the fuel with a set of 100% S&S Diesel Motorsport® injectors, Hamilton valve springs, and Hamilton pushrods. Since it was already equipped with a 12mm CP3 pump from the Phillips Fab 2nd Gen Swap we previously installed, this setup was ready for the extra fuel.
