Those huge 40-inch Toyo M/T tires were mounted onto new RBP 20x10-inch T904 chrome wheels
Starting with the suspension, 2 Brothers teamed up with Off-Road Direct to get the '06 GMC Sierra up in the air. Dave and Brian welded on an Off-Road Direct front solid axle conversion with a Dana 44 to the 4WD, then proceeded to lift the truck a total of 14 inches with leaf springs. Dual Sway-a-Way reservoir shocks keep the ride as comfortable as possible, and a custom front sway bar keeps the body roll down. The Off-Road Direct solid axle kit came with optional dual Sway-a-Way steering stabilizers aiding in turning. Out back, Dave ordered lift leaf springs from Off-Road Direct and bolted those on for added height. Custom rear shock mounts allowed Dave to bolt on the dual Sway-a-Way shocks and coiled yellow diff vent hoses front and rear provide the old-school look the Timm brothers were going for. With a serious lift under the truck, Dave was able to add brand-new 20-inch RBP T904 chrome wheels with red inserts, which were mounted onto huge 40-inch Toyo M/T tires. The look and proportions of a standard cab lifted on 40s brings back an era of lifted Toyotas with 42 Rancho neon-green shocks. Sporting killer paint and a tall suspension, 2 Brothers began to look at making the GMC spin those Toyo tires.
Under the painted hood lies a 5.3L V-8 equipped with a supercharger from Vortech. The blower receives air from an AEM Brute Force intake with Dryflow filter and forces 6 psi of intercooled boost into the combustion chambers. Fuel is supplied from an Aeromotive fuel pressure regulator and high-flow aluminum fuel rails. Dynatech long-tube stainless headers expel the gases into Cherry Bomb exhaust, which was bent by Ken's Auto Repair. The dual exhaust exits out the passenger side, thanks to two chromed rectangular tips. Meanwhile, the tuning chores are handled by a Diablo tuner, and helping the tires spin much easier are 4.56 gears stuffed into the front and rear differentials with Pro Comp covers. Now that Dave could outrun the law-well, at least his brother Brian's police car-the 2 Brothers crew looked to make the interior shine.
Dave has been designing and building killer audio systems for more than a decade, so his personal truck was no exception. Custom door panels kick off the interior and feature two sets of Treo Engineering RSX 6-1/2-inch components, two Treo RSX 5-1/4-inch components, and four 1-inch dome Treo tweeters. The door panels were covered in suede and feature the exposed Treo crossovers with Escalade chrome door handles. Powering the door speakers is a Treo Engineering 80.4 amplifier. Supplying the bass are three Treo Engineering TSX 15-inch subs in a pass-through box behind the seat, which receive power from a Treo 2000.1 amp. Mounted into the suede headliner is a SAVV 10.4 monitor. Sending the signals to the amps and SAVV monitor is a Kenwood 8019 head unit and DVD player, which are powered by a Kinetik battery. Dave purchased all of his audio gear at Benchmark Auto Sound and Security in Springfield.
