One of the first things many off-road enthusiasts modify on their trucks, following the usual suspension lift and rolling stock upgrade, is a custom bumper. You can choose to upgrade the stock bumper with either a winch mount or driving lights, or you can fabricate a completely new bumper that will outperform the stock unit in both areas. We wanted to see how a fabrication shop scratch-builds a new custom bumper, so we took a trip out to IMZZ Industries' new shop in Brea, California, to watch as the crew fabricated a trick new bumper for a Toyota Tundra that would see limited desert use. The goal was to build a bumper that would adequately protect the front end and the wider aftermarket fiberglass fenders, as well as provide a place to mount a skidplate and driving lights.
