Photo 2/38 | 2015 Chevy Silverado 2500 Rear Three Quarter | Four-thousand miles was all the ’15 Silverado had on its odometer when it became a project truck. The owner, Chad Hall, started with some basic tuning, then simply handed it over to Chris Rosscup at Deviant Race Parts (DRP), where it became a development platform for a Duramax 6.6L LML-based compound-turbo system.

Photo 5/38 | Edge Tuner | While monitoring the critical functions of any diesel engine is important, keeping a close eye on the functions of an all-new compound setup—as it is being developed—is even more imperative. In lieu of using gauges for this, Chad chose an Edge Insight CTS and mounted it right on the A pillar so it’s just a glance away.
Photo 6/38 | 2015 Chevy Silverado 2500 Front Three Quarter | Definitely subtle, Vinyl Fire graphic services provided the flat black wrap on the front to delete some of the chrome.
Photo 7/38 | 2015 Chevy Silverado 2500hd Rear Three Quarter | Vinyl vehicle wraps have quickly become the “new black” of sorts, for trucks and their other wheeled brethren. Vinyl Fire of Hayden, Idaho, laid the Alligator colors across the panels of Chad’s Silverado.

Photo 9/38 | Rear Airbag And Shock | The Pacbrake airbags, along with a 3-inch leveling kit from CST Performance Suspension, help a lot to keep the back from squatting too much when Chad or the guys from Alligator head down the road with the loaded 32-foot race trailer.
Photo 10/38 | Drp Sump | Getting a larger supply of fuel out of the tank to feed a bigger, thirstier injection system is always a challenge. Deviant makes a simple, one-hole sump that attaches to the underside of the tank, instead of having to drop the tank and spend countless hours fiddling with a draw-straw style lift system.
Photo 11/38 | Exhaust Tip | The AFE 4-inch dual exhaust—one of the truck’s first add-ons—handles the spent gas from the Deviant Race Parts compound-turbo kit for Duramax LML engines.
Photo 12/38 | Allison Transmission | It didn’t take long for the heat and strain of more power and heavy towing to take their toll on the six-speed Allison transmission. To get it in better than original condition, it was sent out to No Zone Diesel for a rebuild. Dmitri at No Zone rebuilt it with SunCoast clutches and a torque converter.

Photo 14/38 | 2015 Chevy Silverado 2500hd Grille | Vinyl wrap isn’t just for graphics, Chad used flat black wrap from Vinyl Fire to camouflage some of the chrome up front.
Photo 15/38 | Cal Tracks | Even though this wouldn’t (yet) be considered a race truck, the CalTracs traction bars are still practical on the street; they keep the rear axle from wrapping up or twisting while pulling away from a dead stop with a heavy load.
Photo 16/38 | B And W Hitch | Chad uses a B&W Turnover ball for attaching a 32-foot gooseneck race trailer.
Photo 17/38 | Power Steps | Since this truck is a daily driver and tow rig, it’s outfitted with a set of AMP Research’s electric side steps just to make the enter/exit routine much easier.
Photo 18/38 | Shock Reservoir | Tow rigs need more than just added power—they also need to be able to handle a loaded trailer. In Chad’s case, said trailer is often a 32-foot gooseneck that hauls the Deviant Race Parts race truck. CST Performance Suspension’s 3-inch leveling kit features a pair of remote-reservoir shocks and stout upper control arms up front.
Photo 19/38 | Ppe Diff Cover | Heat is the enemy not just of anything that uses oil. PPE’s thicker, finned differential cover helps keep those gears cool.
Photo 20/38 | Transmission Cooler Line | Diesel Race Parts makes a set of heavier-duty replacement transmission cooler lines that directly replace the OEM lines.
Photo 21/38 | 2015 Chevy Silverado 2500hd Duramax Engine | One of the other challenges Chris Rosscup from Deviant Race Parts faced while physically building the first compound kit was fitting it all neatly under the hood. Even as a development package, the AFE air filter, S475 turbocharger from High Tech Turbo, and custom tubing look like they’ve always been there.
Photo 22/38 | S475 Turbocharger | The compound kit for the LML platform is comprised of an S475 turbocharger from High Tech Turbo and the stock turbo and injectors. When combined with tuning from Motor Ops, this combination makes a very respectable 650 hp with a race tune and a reliable 520 hp on the towing tune.
Photo 23/38 | Stock Turbocharger | The compound system currently features the stock ’charger mounted ahead of the bigger S475 unit from High Tech Turbo. Stock fuel injectors are retained, but the kit is being further developed.
Photo 24/38 | Allison 1000 Transmission | The Allison automatic transmission had already begun to show some signs of the strain behind the new power setup, so it was handed over to Dmitri Millard at No Zone Diesel where it was rebuilt with clutches and a torque converter by SunCoast.
Photo 25/38 | Blacked Out Front Grille | Vinyl wrap isn’t just for graphics, Chad used flat black wrap from Vinyl Fire to camouflage some of the chrome up front.

Photo 27/38 | Front Shocks | Leveling kits are more intended for weight distribution and handling than they are for general truck aesthetics. Chad’s rig features CST Performance Suspension’s 3-inch leveling system, which includes stouter upper control arms and dual remote-reservoir shocks.
Photo 28/38 | Fuel Lethal Wheel | Fuel’s 20x9 Lethal wheels have become more than just a little popular lately, and they do look great. However, for Chad’s truck they are more for go than show. The Northwest can offer up challenging weather at any time of the year, and the wheels, paired with the 305/55R20 Toyo Open Country AT II tires, are more than up to the task of handling inclement conditions.
