1992 GMC K1500 - Fool-Size Fun

Posted in Features on September 16, 2014

It takes a special kind of person to wheel a fullsize truck. When we say “wheeling” we don’t mean driving down dirt roads, but following Jeeps and buggies through tight rocky trails. Some might call this foolish, but Jeff Noggle has taken up this gauntlet, picking lines above the expansive hood of his ’92 GMC.

The different-color body panels betray past sheetmetal smashing, but the great thing about this generation of truck is that parts are easy to come by. Jeff knew what he was getting into with this truck, having built several fullsize Chevys for mud and rocks. He put everything he learned from those rigs into building this truck, with bigger axles, more tire, and enough suspension to ensure that the tires stay on the ground.

The factory interior is still in place, right down to the bench seat and stock steering wheel. Jeff Noggle did build a full rollcage from 13⁄4x0.120-wall steel that goes through the dash—a wise investment for the type of wheeling he does.
