2009 Chevy Silverado 3500 Buildup - Anatomy Of A Custom Truck

After unplugging the factory light bulb sockets, the new Recon lights were plugged into the OE harnesses.

For all you dualie owners out there, this mod should be on your to-do list. These LED cab roof lights really clean up the annoying yellow lights on top of the cab.

As you can see, the bright orange doesn't exactly fit the dark theme of the truck build. Not to worry, Recon will fix this in a matter of minutes.

Again, simply using a screwdriver, Reuben removed the factory lights and swapped them in favor of the smoked Recon lights.

Another simple mod, these LED marker lights for dualie fenders will add some much-needed styling to those bulging sides.

But after simply using a plastic pry tool to free up the lights and unplugging the wiring harness...

Safety is important and all the Recon LED lights are DOT/SAE compliant, including this LED third brake light.

We were now ready for the Bully Dog GT tuner. This new tuner simply plugs into the OBD-II port under the dash and instantly provides 15 different engine vitals, four on-the-fly power levels, and it has the ability to read and erase diagnostic codes. As a bonus, the GT tuner also receives internet updates, so your truck will have the latest and greatest tuning for years to come.

Perfect for towing, increasing mileage, or for just hauling the mail, the Bully Dog GT tuner really woke up our turbo Duramax.

To maintain cool running temps for our one-ton gears, we added a Mag-Hytec diff cover to the dualie. Featuring a built-in dipstick, drain plug, and larger fluid capacity, the Mag-Hytec cover is the best on the market.

As an added bonus, the Mag-Hytech cover also looks burly and with the external fins, it lowers differenital temps by as much as 50 degrees. The Royal Purple gear oil keeps the gears protected.
