🔧 RANDALL IS GETTING IT DONE! 💪

Here’s Randall hard at work on a 2012 Jeep Grand Cherokee motor swap! 🛠️ The motor is out, and he’s busy swapping over the parts that need transferred before getting everything ready to go back in!

We appreciate our crew and all the hard work they put in every day! 👏

🚛 CONTRACTORS & TRAILER OWNERS — WHEN WAS THE LAST TIME YOUR TRAILER WAS CHECKED? 🔧

Your trailer works just as hard as your truck, but some of the most important parts can wear out without you ever noticing!

⚠️ Things like:
🔹 Worn or failing wheel bearings
🔹 Brake problems
🔹 Cracked or dry-rotted tires
🔹 Bad wiring, lights, or connectors
🔹 Worn suspension components
🔹 Loose lug nuts
🔹 Damaged safety chains or couplers

🔧 Let us check your trailer over and inspect for common wear and tear before small problems turn into costly repairs. Keep your trailer safe, reliable, and on the road longer!

📲 Share this post with a contractor or trailer owner who needs to hear it!

🔧 UNDER THE HOOD - TIMING CHAIN JOB! 🔧

This engine is stripped down and ready for timing chain work! ⛓️ A timing chain keeps the engine’s internal components working in sync, and when problems arise, getting it repaired correctly is important to protecting your engine!

We take pride in doing the job right and getting you back on the road! 💪🚗
