This month's Fantastic Four involves a bone-stock white '05 Chevy Silverado 2500 HD 4WD Crew Cab longbed powered by a 6.0L V-8. Our assignment was to enhance the Silverado's ride height, appearance, power, and fuel efficiency. The overall size of the 2500 HD Silverado is intimidating, with its 167-inch wheelbase, it is no fun at all to park. To bring the truck up a few inches without breaking the bank, we installed a Pro Comp front torsion bar Level Lift and a set of Mamba M2-8 20x10-inch wheels wrapped in Nitto Durra Grappler Highway Terrain LT275/60R20 (a little taller than 33 inches) rubber. The fuel efficiency and power was improved by installing a CGS Motorsports air intake and after-cat exhaust system.
The first stop of the day was at 4 Wheel Parts Performance Center in Santa Ana, California, where Raul Meyers, Mark Allen and Chuy installed the leveling lift. From 4 Wheel Parts, we took a road trip to CGS MotorSports in Pomona, California, where Casey and Ron Scranton installed an air intake and after-cat exhaust system. Once the dust had settled, our wallet was out less than $3,000 and out truck looked ready to tow, haul, or handle any other duties we threw in its path. For one day's worth of work, the Chevy performed on a whole new level.
 To raise the front ride height,...  To raise the front ride height, a Pro Comp torsion key leveling lift kit will be installed. This allows the front torsion bars to be re-indexed, lifting the front suspension approximately 21/2 inches. The kit also included shock extenders. |  Raul, from 4 Wheel Parts in...  Raul, from 4 Wheel Parts in Santa Ana, California, used a tape measure to check the factory front ride height by measuring from the center of the wheel to the front wheel well lip, which was 23 inches. |  After the grounded measurements...  After the grounded measurements were taken, the Silverado was lifted and the factory wheel/tires were removed. After removing the torsion bar adjusting bolt, a special torsion key tool was used to release the torsion preload on the key to allow Raul to remove the block. |
