Fat Fender Garage, an Arizona restoration shop, revealed the GT/FX at SEMA. The truck is based on a 1956 Ford F-100 and features a reshaped steel body.

Why it matters

The reveal shows how restomod builders are pairing classic truck bodies with modern performance hardware. It highlights a growing market for custom trucks that combine vintage styling with contemporary engines and chassis.

The GT/FX uses an 800-horsepower Ford Coyote 5.0-liter V-8 with a 3.0-liter Whipple supercharger producing 750 pound-feet of torque. It rides on 315/35R-20 Toyo Proxes Sport 2 tires at the rear.

The players

Fat Fender Garage

Fat Fender Garage is an Arizona-based restoration shop that built the GT/FX and its FF1 Performance Coilover chassis.

The details

Fat Fender Garage reshaped the 1956 F-100's steel body with a flatter hood and roof and wider front and rear fenders while leaving the original grille unchanged. The truck pairs a Ford 10R80 10-speed automatic with Wilwood disc brakes and carbon fiber side mirrors, and its tailgate drops at the push of a button.

Roadmap

The GT/FX applies the Ford Coyote 5.0-liter V-8, a crate engine that has become a common swap for classic vehicles, into a 1956 F-100 body. It follows a broader pattern of restomod builders pairing vintage truck bodies with modern powertrains.

Buyers interested in a restomod truck like the GT/FX would need to consider the build's cost and availability, neither of which was disclosed. Owners of such a truck would face the practical realities of maintaining a high-horsepower supercharged engine and custom chassis.

The takeaway

The GT/FX shows how classic truck bodies can be re-engineered around modern performance components while keeping their original character. Readers following custom truck builds can watch whether restomods like this move from one-off show vehicles into available production builds.
