Been using a lot of products from our friends recently,customer having us replace his stock turbo for a better more beefy fleece performance cheetah turbo in a 2016 ram 2500, with there oil feed line and oil drain line replacement kits for better looks and simplicity. Another customer brought there 2007 6.0 Powerstroke in for a code for fuel sending unit malfunction and upon removing the stock sending unit the pickup screen was plugged. So we put in the fleece performance fuel sending unit assembly, and compared to the stock one the fleece will hold up to a lot more and carry more fuel volume for the fuel system. If you’re wanting to upgrade your truck with any fleece products come see us and we will get your truck running better than ever.

Customer brought in their 2016 ram for a loose heater grid wire and got very lucky that when it broke it welded its self and didn’t fall into the engine. So don’t wait call and make an appointment to swap out the old restrictive intake horn and grid heater and have us install the awesome monster ram to save your engine! We’re also installing a coolant filtration kit on it to keep this cooling system clean!

🚛🔧 Another truck back on the road — running the way it should!

During a recent inspection, we found a fuel filter that needed immediate replacement and a glow plug that wasn’t functioning properly. Instead of just telling the customer, we sent real video clips showing exactly what was going on — because we believe you deserve to see what your truck needs.

✅ Fuel filter replaced
✅ Glow plug diagnosed & repaired
✅ Customer kept informed every step of the way

➡️ Before & after fuel filter replacement
➡️ Diagnostic video screenshots showing the difference between a failing and properly working glow plug

At our shop, transparency matters. No guesswork. No surprises. Just honest diesel repair and quality work you can trust.

🔋 Truck won’t start? Check the battery first! 🔧

Dead batteries are one of the top reasons diesel trucks refuse to crank on a Monday morning. Cold temps, corrosion, or just old age — your battery might be the culprit.

🚛 Stop by Trilogy Diesel for a quick battery test and inspection.
We’ll get you powered up and back on the road in no time.

🛠️ DIRTY FIND OF THE DAY 🛠️
Pulled the intake and found this clogged heater grid—absolutely packed with soot and grime! 😷
This kind of buildup can choke airflow, kill performance, and even mess with cold starts.
Diesel engines need to breathe—don’t skip that intake inspection! 💨🧰

🚨 Don’t Be That Truck! ⛽️💀

Running out of diesel isn’t just embarrassing…
It’s a fast track to air in the lines, injector headaches, and a bad day. 😬

👉 Top off before that needle hits E.
👉 Save yourself a tow bill (and our "I told you so").

Your truck deserves better. And so do you.
Keep it fueled. Keep it alive. 🔧💪
