From large parts to small parts, BIGFOOT 4×4 innovators will engineer custom parts that are unique to the monster truck industry. BIGFOOT 4×4 says the latest truck, BIGFOOT 21, out-performs previous trucks in BIGFOOT 4×4’s fleet. Reaching new heights and achievements in maneuverability, modification of parts were needed to meet performance demands. BIGFOOT 4×4’s shop foreman and leader of research and development, Bryan Bertoletti, is behind recent innovations.
