Jackson Strong, Jacko, grew up riding on his family's farm in Australia and joined the Crusty Demons as a teenager. Brian Deegan invited him to ride with Metal Mulisha and he spent six months at Deegan's Temecula compound. He went on to ride the international FMX tours and compete in X Games Best Trick.

In 2011 he landed the first frontflip at X Games and won gold. He won again in 2012 and kept developing frontflip combinations and the Jack body varial. His jackhammer frontflip took Best Trick gold at Ventura in 2024. Jacko's Headstrong films show the riding and testing behind those tricks, using the ramps and foam pit at his Australian compound before taking them to dirt and competition.
