1957 GMC Chevrolet Truck - Twin Turbo

1957 GMC Chevrolet Truck - Twin Turbo


This is the biggest machine ever to roll out of the Shack. Beginning life in the US way back in ‘57, this truck came to us in a bit of a sorry state, although the chassis and cab had held up well to the rigours of time. 


We begin by disassembling the entire vehicle and taking it back to bare metal. From there, Jack and the team began to restore, repair and improve, always with one goal in mind - creating a British-built truck that would put Jack’s Shack on the map both in the UK and in the US - with this huge machine, we believe the team has done just that!


This truck is immaculate inside and out, there is not a scratch, not a bump, not a ridge, not a scuff and not a mark. There are new cars that leave factories that are not as clean as this machine!


Under the ‘hood’ much has changed, modern running gear and DAF 45 axels are under the control of a Z1 5-speed gearbox, air clutch and a hugely powerful Cummins engine, complete with a unique twin-turbo setup - fitted right here at the Shack.


With all that power, we thought it was right to seriously beef up the brakes, in fact, replacing them entirely, with a set of air-over-hydraulic brakes that, in the American parlance, ‘stops on a quarter and leave a dime’. 


An air-ride system, with roughly 5-inches of travel, leaving the truck resting on its sills, makes for both a great showpiece, a practical option for speed bumps and a great ride. 


Outside, huge house-built exhaust stacks give this truck yet another entirely unique aspect, although it’s hard to say that they dominate, as that accolade must fall to the wood-finished, remote-controlled, custom tipping bed, complete with hidden ramps and built-in lockers. The bed measures in at 18ft long and 6ft 9inches wide, giving the truck in its entirety a length of 26ft! 


The exterior will be completed by a one-off paint job, befitting this already award-bound machine. Think Rootbeer red and metallic grey. 


Inside, the cab will play host to a classic three-seat bench, covered in a rich tan leather. While there will be a nod to modernity in the form of a GPS speedo system. 


This really will be a one-of-a-kind vehicle when complete, ideal for anyone with a car or motorbike collection they want to transport in unrivalled style. Or someone who simply loves a proper American classic done right.
