Another cool customer build coming through the shop! This L5P is equipped with the McGaughy’s Suspension 4” lift and 37” tires. This is the best way to clear 37’s and maintain good ride quality.

For all of your Duramax needs call Duramax Service Center.

You don’t see em this clean very often.
This LBZ Duramax rolled into the Service Center with just over 100k original miles. We got this one a new water pump and back on the road where it belongs.

With GMT800s only getting more popular, finding a clean, low mile example like this is getting harder and harder.

Exhaust leaks on the L5P motors are a common issue here at the shop. We use the DmaxStore L5P manifold stud kit and gaskets to ensure a proper seal once this job is done.

Need more range without hauling fuel cans around?
We recently installed a Titan Travel Trekker 50-Gallon Auxiliary Fuel Tank on this GMC.

✔️ Adds 50 gallons of extra diesel capacity
✔️ Automatic fuel transfer system
✔️ Fits under most tonneau covers
✔️ Maintains valuable bed space

Whether you’re pulling a trailer across the state or just tired of hunting for fuel stations, an auxiliary tank is one of the best upgrades you can make to your truck.

If you’re interested in a Titan Tank or other fuel system upgrades, give us a call and we’ll help you find the right setup for your truck.

This LBZ came into Duramax Service Center for an inspection and some maintenance, but after getting it up in the air we found some original parts that have been holding strong for over 10 years. Always cool seeing parts that have actually stood the test of time.

To freshen up the front end, we added a steering gearbox along with new Kryptonite pitman arm and UCAs. Now this truck is running a complete Kryptonite front end setup and ready for plenty more miles.

That’s the difference when companies build parts to last.

Step-by-step install on the Ram Air Intake for the L5P.

More airflow, better throttle response, and CARB-legal; this is one of the easiest upgrades you can make to wake your truck up without sacrificing reliability.

If you want more out of your turbo without going down a rabbit hole, this is it.

100k miles on a 2.8L Duramax means one thing…

Timing belt service.

Skip it and you’re gambling the entire engine.

This Colorado is getting the full service, belt, water pump, tensioner and seals, so it’s ready for the next 100k.

This customer upgraded to the new Stage 3 Leveling Kit paired with 2.5 Performance HTO shocks for a smooth, controlled ride. One of the most critical upgrades in any leveling kit is replacing the factory upper control arms. OEM arms are flat and can bottom out on the frame perch, creating unnecessary stress on the ball joint and arm—sometimes leading to complete failure and leaving you stranded.

Kryptonite control arms are engineered with added droop travel to match the increased range of a leveling kit, eliminating frame perch contact when installed correctly and delivering reliable, long-term performance.
