Truck Assist Jailbar

Truck Assist Jailbar

Resto completed August 2018

When we launched our Truck Assist brand, we knew we needed something special to promote it! Enter our bright orange 1946 Ford Jailbar - ironically found just outside Orange, NSW!

The Truck Assist team took the body and soul of this old vehicle and gave it some modern technology and safety upgrades, including, a six speed manual transmission, front end disc brakes; and a new V8 diesel engine. We also added some creature comforts ranging from air ride seats to twin fridges in the tray!
