🔥 ANOTHER BANKS UPGRADE IN THE BOOKS! 🔥

This 6.7L Cummins came in for a serious airflow upgrade, and left with a fresh Banks Monster-Ram Intake System installed and ready to work.

✅ Removed the restrictive factory intake horn
✅ Cleaned years of soot buildup from the intake grid heater area
✅ Installed the Banks Monster-Ram with upgraded plenum design
✅ Improved airflow and throttle response

The amount of carbon buildup hiding inside these factory intake systems is always eye-opening. A clean intake path combined with the Banks system helps these trucks breathe easier and perform the way they should.

Here’s a good example of why routine brake inspections matter on heavy trucks.

These drums came in with severe heat checking, cracking, and surface damage from excessive heat cycles and wear. You can clearly see the spiderweb cracking throughout the braking surface — once drums get to this point, they’re beyond safe service limits and become a serious safety concern.

Common causes of damage like this include:
• Worn brake shoes
• Out-of-adjustment brakes
• Dragging brakes
• Excessive heat from heavy loads or repeated hard braking
• Ignoring early warning signs like vibration, pulling, or overheating smells

On heavy-duty applications, failing drums don’t just risk poor braking performance — they can lead to catastrophic failures, damaged wheel ends, downtime, and unsafe road conditions.

✅ New drums installed
✅ Braking surface restored
✅ Back on the road safely

If your truck has brake vibration, excessive heat, uneven braking, or you’re due for an inspection, don’t wait until it turns into a major repair.

Talk about a failed valve cover gasket on a Chevrolet 6.5L Detroit….😳

The old gasket was so cooked and brittle it looked more like burnt plastic than rubber. Oil seepage everywhere, dirt packed on the block, and that classic “why does it smell like burning oil every time I drive it?” diagnosis😂

Sometimes the little leaks turn into BIG messes when they’ve been ignored for long enough. Safe to say this one was overdue for some attention 👨🏻‍🔧🔧

Fresh gasket going back on and getting this old 6.5 cleaned up the right way 💪🏻

“Just a simple tune-up,” they said… 😅

This Dodge Charger rolled into the shop for plugs & coils after a misfire concern. Pulled the intake and found plugs that were LONG overdue 👀

Then one thing led to another…
➡️ Transmission issues
➡️ Bad driveshaft center support/carrier bearing
➡️ More teardown than expected

Now she’s getting the full treatment instead of a band-aid fix 💪

Sometimes the small symptoms are just the beginning of a much bigger problem and catching it before total failure saves a customer from an even worse day later on.

Ended the night getting this Mack concrete pumper back up and rolling after a failed wheel seal took out the bearings. Pulled apart, cleaned up, replaced, and back together so they could get back to work first thing this morning!

Breakdowns don’t always happen during business hours — but we do our best to keep our customers moving when it counts. 💪

This International came in after the front cover failed — causing a major teardown to get everything repaired correctly. 🔧

Pulled down the front of the engine, replaced the damaged front cover, inspected components, cleaned everything up, and got it all reassembled and sealed back up the right way. ⚙️

Breakdowns like this are exactly why quality repairs and attention to detail matter on heavy-duty equipment. Glad to get this one headed back in the right direction. 💪

Keeping the heavy stuff rolling 🔧🚛

Got this International back together with a new wheel seal after a pretty good mess inside the hub. Leaking wheel seals don’t just make a mess, they can contaminate brake shoes, reduce braking performance, and turn into a much bigger repair if ignored too long.

Cleaned up, resealed, and back ready for the road the right way 👌

If your truck is slinging oil around the wheel ends, smelling hot, or showing brake contamination, don’t wait until it becomes a roadside problem.
