One Off Design is no one-hit wonder. Its owner, Robbie Robinson, has built an '02 Corvette Z06 and a '62 Cadillac. But he wasn't sure if his '02 Denali project would stand as proof of the Santa Clara, California, shop's accomplishments, or if it would nose dive into its namesake: Nero Inferno, aka Black Hell. Hang onto your winter clothes, Robbie, and put away the pitchforks, because you won't be riding south in this Denali. It's too good for that
One Off did all the work on this GMC. Mercedes Black Pearl cloaks the upper half of the body. Khamla Seelapasay coaxed the lower fringe of that black into curling flames that he intertwined with licks of Mercedes Red Pearl, offsetting the Lamborghini Orange that dresses the lower part of the Denali's body. Herb Martinez pinstriped classic green and blue hot-rod strings on the cargo hatch and some blue to outline the split line's flames. Clean and shaven, the body is bereft of door handles, tailgate handles, and an obvious gas filler. A Sir Michaels roll pan with a custom bottom by One Off eases the eye's journey across the Denali's rump, and a custom taillight conceals the relocated fueling point behind it. Stainless steel running boards and an Escalade rear glass, back pillars, and roof rack lend a touch of class. A diamond-wire grille from Stull underscores the flare of the hood's ram-air nostrils.
An overall 3/5 drop gives the Denali an easy-going stance. Chip Foose 24-inch Lusso wheels wrapped inside low-profile T/A KDW BFGoodrich g-Force 305/352R24 tires spin on McGaughys two-inch drop spindles. Hotchkis sway bars keep the Denali vertical. Baer's AlumaSport two-piston calipers and 14-inch EradiSpeed rotors and stainless lines put the brakes on the vehicle's forward momentum. Peel away the hood to get a view of the engine cover, airbrushed by paint master Khamla, and of the upgraded Vortec 6.0L eight-cylinder powerplant sporting JBA Cat4Ward headers, an AEM intake, and alternator from Powermaster. One Off also built a modified throttle body and a custom, 3-inch exhaust connected to a MagnaFlow muffler. A Hypertech power programmer tweaks the tranny
Inside the Denali is a rolling wilderness of 'glass and electronics. A mountain of mobile goodies dominates the cargo area. Khamla built a fiberglass enclosure for some Alphasonik gear: three down-firing 15-inch PSW8154 ALPHA 800 subwoofers that bristle from the top of it, three PMA800DA 800-watt mono amplifiers for the subs, and a PEQ20LX sound processor. A PMA4150A 240-watt, four-channel amplifier for the component speakers clings to the inside of the rear hatch. Two Optima YellowTops are located by the sub box. Four 6-1/2-inch component speaker sets were broken up with the mids placed two per door in custom speaker pods. A tweeter was put in each A-pillar. Two more were put in the 'glassed center console above an Audiovox 7-inch monitor, providing a center channel for passengers in the rear seats. A 13-inch Audiovox screen is in the front of the center console, at the dash. Both monitors are fed by an Audiovox AVD300 DVD player in the center console. Aaron O'Brien wired the entire audio and video system
The fiberglass on the dash and center console was painted orange, while the 'glass on the doors, tailgate, and headliner received a dose of black. A Cadillac Escalade gauge cluster provides the driver with engine readouts, while Trenz a shifter and billet pedals are reserved for the hands and feet. Toupals Upholstery in San Jose, California, lined the stock seats with Black Allante and Wallabie upholstery. The floor is covered with black Bentley carpeting.
Robbie thanks MHT who manufactures and provided the Foose wheels, Baer Brakes for the product it contributed, his family, and the crew at One Off (Khamla, Mario, and Wes) for taking the risk to support this project. Many of the Denali's upgrades were built from scratch, and Robbie is grateful to everyone who committed their time and resources toward a show vehicle that would evoke an unknown result. But the bigger the risk, the bigger the reward, and clearly, Robbie came out on top.
