This 1967 Jeep Kaiser M715 is The Metal Shop’s flagship monster truck. But it’s more than just a monster truck, it’s the driving force behind the constantly evolving chassis design now seen all over the sport. The Shaker is the product of a lifelong dream between a father and a son. Rick Disharoon and his son, Ryan Disharoon, first developed the Shaker for mud racing. By 2014, Shaker had been taken to the next level – ready to compete in the monster truck circuit. Its namesake is a tribute to the men and women who served our country and paid the ultimate sacrifice during the Vietnam war.
