Santa Clarita resident Robb Robinson wanted to show what his body shop, One Off, could do. So when it came time to lay the smackdown, the choice was made to attack the sheetmetal of Robb's '02 GMC Denali. A shave was in order, so the MIG welder was plugged in and shaped pieces of sheetmetal were burned to the stock panels, removing all the external handles and third brake light.

The air compressor was cranked up to 125 psi and the impact spun the bolts off that held the rear bumper to the Denali frame. In its place, a roll pan was screwed to the bottom of the rear quarter panels. Then the cut-off wheel was snapped to the compressor and a carbon blade spinning 12,000 rpm sliced through the sheetmetal to shape a rectangular hole in the lower section of the roll pan.

The new hole in the roll pan was smacked with a hammer, while being supported by a mandrel to form the flare that surrounds the freshly cut hole. A chromed MagnaFlow Corvette-style exhaust exhales the V-8 engine through the custom-built roll pan. The gas door was welded and smoothed to clean up the body lines. Using a cut-off wheel, a welder, and the hinge from the old gas door, the rear taillight was given a second function as the new gas door.

With the Foose's Lusso 24x10-inch five-spoke wheels wrapped in BFG 305/35/24 G-Force T/As, the stance on Robb's Denali was going to need a droop. The techs at One Off took the impact gun to the upper and lower ball joints so the stock knuckle could be replaced with Mike McGaughy's drop spindle and torsion key. Out back, McGaughy's drop goods came with enough drop to level the Denali out.

The five-spoke Lusso 24-inch wheels have huge voids between the spokes, displaying the underlying brake system. While the suspension was being upgraded, the stock brake system was replaced with Bear's Eradispeed 14-inch rotors and aluminum sport calipers. All the Caddy goods were adapted to the Denali's exterior, including the roof rack, B-pillar caps, and rear glass.
