Wolf In Wolf’s Clothing: 2003 Chevrolet 1500 2WD

A sensible individual has to respect an impressive truck build, no matter what the make or model. Personally, we’re pro-Chevy here at OFF-ROAD magazine, but we think even the most anti-Bowtie guy would have to appreciate the amount of work that went into James Mullinex’s ’03 Chevy 1500.

Between the construction performed by both KibbeTech in Simi Valley, California, and A&A Corvette in Oxnard, California, this Chevy has turned out to be just as mean as it looks. With over 500 horsepower feeding through a 4L80E to a built 9-inch rearend, this KibbeTech long-travel truck—packing over 20 inches of front suspension travel—can absolutely fly over rough terrain.

Thirty seven-inch Baja T/A tires tuck under Glassworks and Trailer Products fiberglass, which allow the front tires to compress a full 10 inches upwards from ride height. James —who works at A&A Corvette building almost quadruple-digit horsepower engines—built himself one serious LQ9 that sits under the ’03’s slanted hood. Even after the parasitic loss of power through the drivetrain, James’ engine pumps out 435 horsepower to the rear wheels.

And like any other project, James’ truck is still not quite done. His next step is to connect the engine cage and bed cage in between with a full interior rollcage that will follow through the fire wall to the engine cage and out the rear of the cab to the bolt-in bed cage. Not only will it bring safety to the truck, it will add rigidity and improve the way the truck works.
