OK, editors are known for exaggerating and even I can be convicted of pumping things up a tad too much. But, when it came time to fire the ignition and go do some slalom runs, the Sierra went from work truck beater into Project Novakane. With a deep rumble from the Banks Monster exhaust and bulldog-like looks from the lowered suspension, our truck was ready to have some fun. Throttle response was instant, we could hear the throttle body actually sucking air into the intake, and what may have impressed us the most- the Nitto NT05 tires were completely planted. With a treadwear rating of 200, the tires are much stickier and literally eliminated tire spin during hard launches. Despite being designed for lifted and leveling kit-equipped trucks, the BMF wheels fit our lowered GMC perfectly and the deep lip gives the Sierra a unique, race-style look. Handling was impressive, as the slalom times show, we went through the cones 12 mph faster (an incredible feat for just basic bolt-ons). Hotchkis and McGaughy's lowering components worked very well together and combined to give the 4,300-pound GMC a compliant (though for some it may be too stiff for a daily driver) ride with sports car-like turning abilities. We spent just shy of six grand and considering the improvement, we can't think of anything that can transform your truck overnight better than these mods. Next month, check out how well the track-installed AP Racing big brakes, from Stillen, brought the Sierra to a halt from 80 mph.
