Greenfield Customs works to bring your custom design to life. Whether bending, cutting, or shaping, we can handle it all. With a variety of tools and skills in our shop, we can cut signs — wooden, aluminum, and stainless steel, to any shape or size.

• BEGINNING IN THE 1980’S

  Tim Greenfield developed his own way of doing things with monster trucks. By starting with junkyard parts and a few friends with various skills, he turned his scrapyard truck (originally called the Predator) the Intimidator, into a Hall of Fame, all-time classic.
