This month’s Fantastic Four tech install is on a 2011 Chevy Silverado 4WD. These are amazing trucks from the factory, but could use a bit of help in some areas. The owner bought the truck to haul dirt bikes and motocross gear all over Southern California, Arizona, and Nevada. We decided on a moderate lift to give the truck more ground clearance when off-road, an intake and exhaust for better engine respiration, and beefy wheels and tires for improved off-road safety and capability.

For the suspension, we contacted Summit Racing and ordered a Skyjacker 6-inch lift kit. We also upgraded the leaf springs and rear shocks since the owner would be hauling heavy dirt bikes around. The intake we went with was AEM’s Brute Force intake kit from autoanything.com. This came with the new Dryflow oil-free filter for ease of use. We ordered a Cherry bomb exhaust, also from Summit Racing, since the owner wanted a rowdy sounding truck and according to Cherry Bomb, they have been disturbing the peace since 1968. Finally, for the rolling stock, BMF was contacted for their M-80 wheels in stealth finish for a mean look, and a set of General’s new Red Letter Grabbers in the 35x12.5R20 size were ordered from 4 Wheels Parts. We had heard good things from other truck owners about the Grabbers and were excited to see how they performed.

For the intake and exhaust install, we used our Tech Center and Truckin’s Editor Dan Ward handled turning the wrenches and holding back the expletives. The truck was then taken to Trader’s Truck Accessories, in Santa Fe Springs, California, to have the suspension installed, along with the wheels and tires. Once we arrived, technician Ox Higgins made quick work of giving the truck a better stance and new shoes. Follow along to see how we upgraded Chevy’s newest pickup.
