The owner of this 2006 GMC Sierra 3500 came to WJPE looking to transform his unassuming stock truck into an awe inspiring, daily driven show truck. The first step in the transformation was for Wayne to design, fabricate and install a custom 4 inch diameter exhaust system with dual 6 inch diameter chrome stacks. Next we needed to make the truck match the massive stacks. We decided the best way to accomplish this was to install an 8 inch suspension lift kit. We chose to install a Superlift lift kit because of their reputation for building high quality products engineered to withstand the stresses this vehicle will exert on them. Once the lift kit was completed, we turned our attention to the now puny looking stock wheels and tires. We swapped the stock wheels and tires out in favor of a set of 10 lug 22.5 inch diameter wheels from a Freightliner tractor trailer. We wrapped these massive wheels with a set of Goodyear all terrain tires. While test driving this now massive truck, we noticed two issues caused by the increased height and weight. The factory brakes needed some help to slow the truck down, and under acceleration the rear axle would wrap up the leaf springs too much. To help out the brakes, we installed a Pac-Brake exhaust brake and to control the axle wrap we installed a pair of RCD ladder bars.

After driving the vehicle for a couple months, the customer decided he wanted WJPE to install a dual front shock setup with remote resivoir shocks. The only problem was we could not find a shock hoop that would work with the Superlift lift kit. Well, it was not really a problem with Waynes fabrication skills. We ordered in a dual shock hoop and some ¼ inch thick steel mounting tabs. After mocking the hoop in place we cut, sectioned, welded, grinded, and painted the now custom shock hoops. We welded the mounting tabs to the top of the frame rail to mount the lower legs of the shock hoops. To finish the dual shock hoop installation we installed a set of Pro Comp MX6 adjustable remote resivoir shocks. With the trucks looks now transformed, we turned our attention to the drive train and fuel system. First, we installed an Edge Juice with Attitude module, an AFE cold air intake, and a FASS fuel system. These modifications netted approximately 100 hp and 200 lb/ft of torque. Now the truck runs as good as it looks!!

The customer returned a few months later looking for more power. WJPE warned the customer that additional power would hurt the longevity of the transmission. The customer decided that if the transmission did not hold up, he would have us get a transmission built to withstand the additional power. With that understood, we activated the “hot unlock” on the Edge Juice with Attitude module and installed a Snow Performance water/methanol injection system. The “hot unlock” netted approximately 20 hp and the water/methanol injection not only netted approximately 70 hp, but also reduced exhaust gas temperatures by 150 degrees.

When the transmission finally gave up, we installed a Suncoast stage V transmission and torque converter. We decided to use the Suncoast transmission and torque converter because of their unconditional 2 year warranty, plus they have rated the transmission to handle 800 RWHP and 1400 lb/ft of torque. With the transmission issues resolved, it was time for even more power! We were already pushing the limits of the factory cp3 injection pump, so we decided to install a dual cp3 pump kit by ATS. This kit adds a second cp3 injection pump driven off of the engines’ accessory belt and electronics that allow the two pumps to work together to supply the engine with all the fuel it needs.

We needed more airflow to burn all of the fuel the dual cp3 pumps were supplying, so it was time for a turbocharger upgrade. Due to the massive amount of air the engine needed, we chose to install an Aurora 5000 turbo upgrade kit by ATS. This turbo is absolutely massive compared to the stock turbo. The Aurora 5000 turbo is capable of flowing over two times more air and twice the boost psi of the stock turbo. With the capability of producing 70 psi of boost we absolutely need to install a set of ATS head studs.
