GM rolled out its redesigned HDs earlier this year, so we thought it would be cool to get a hold of one and then do some simple Fantastic Four upgrades to the intake, exhaust, suspension, and wheels and tires. The new HDs certainly look fresh, but they share more with their last-gen versions than you think. The suspension in the '07 HD is essentially the same as the '06 models, which means the aftermarket manufacturers only have to update the labeling on their lifting and lowering kits. We went with a 6-inch suspension lift kit from Bulletproof Suspension that was already in existence for the '06 models. The Duramax 6.6L diesel in the '07 HD is certainly new, if nothing else than for its aggressive, EPA-mandated emissions controls. Rolling Big Power (RBP) provided an aftermarket exhaust system to replace the OE system. At the other end, we nabbed a Volant intake system. Toyo was chosen for a set of 35-inch tires and the new 20x10-inch wheels came from RBP. The gents at 714 Motorsports in Westminster, California, installed the products onto the truck for us. Shall we begin?
