1993 Chevy 1500 - Brace For Impact

More than a decade ago, this 1993 extended Chevy 1500 4x4 showed up at the still-budding doors of WFO Concepts, in Auburn, California. Its owner had given the truck a 4-inch IFS lift, a Vortech supercharger, and bigger tires ... along with a new frame, a few new rear axles, and a couple new paint jobs. The truck just wasn't holding up to the abuse it was getting with its larger tires, more powerful engine, and owner's aggressive driving style. The one thing the truck did have going for it was someone willing to spend the money to make it work right. After reading an article about a Chevy solid-axle swap done by WFO Concepts, the lucky truck's owner dropped it off for a massive makeover, at WFO's discretion. His only demand: It must fit 44-inch Boggers.

Off came the entire independent front suspension and everything suspending the rear. The truck was gutted under the framerails as Trevor and Beau Huiskens went to work building a new subframe to hold the new suspension links. The Huiskens brothers built a three-link in the rear and a four-link in front using SolidWorks to create a suspension that cycles 16 inches with zero degrees of caster change.

To feed the front Dana 60 and rear Dana 70 axle, an NV4500 five-speed manual transmission and Offroad Design NP203/NP205 dual transfer case setup with Tom Wood's driveshafts was used in place of the stock NV3550 and NP241 combination.

With the truck sitting on suspension, WFO went to work adding a '93 Yukon fuel tank behind the rear axle and a '93 Suburban fuel tank in front of the rear axle, giving it a 72-gallon capacity. With all that work into it, the Huiskens brothers decided that only custom-bent-and-welded 1/4-inch plate bumpers would do.

In both the front and rear, WFO Concepts cut, bent, and welded 1/4-inch steel plate until custom bumpers were formed.

Needless to say, the then-owner couldn't have been more pleased. Fast-forward 10 years, and the truck had been reduced to "dust collector." It wasn't getting used the way it should, and by chance it found its way back into the hands of the guys at WFO Concepts, who bought the truck for their own collection.

Upon seeing the truck in WFO's garage, we coaxed them to go out for an early morning shoot while we were in town. What started as a leisurely trip out for a few photos turned into an underwear-grabbing experience for Trevor Huiskens.

Did he save it? You bet. He held on tight, didn't lose his head, and turned into the roll while hitting the throttle and bringing the truck back onto its wheels.
