A chassis built to support 1,000 lb-ft of torque
Watch Roadster Shop engineer a custom Spec Series chassis for LokJaw, our supercharged Duramax-powered ’66 Chevy big-window longbed. Not only does the chassis have to accommodate a much larger engine than a typical C20 pickup, but it must also withstand over 1,000 lb-ft of torque. Not to mention it has to lay flat on the ground. In other words, they have to create a Swiss Army knife.
