Stress Factor the Legend was constructed by Aaron Tuana of Monster Trucks W.A as a tribute to both the original Stress Factor and the late Mike Tuana. It operates on the former Stress Factor chassis, which was re-built in 2022.
It was initially set to debut at the Claremont Showgrounds 'Showground Slam' in May of 2025, however the truck would experience issues and was unable to compete. The team requested the body not be shared online until it was announced officially. The truck made its long awaited debut at the Mandurah Boat, Caravan, 4WD and Camping show in October of 2025.
The name is a play on the phrase 'the man, the myth and the legend', with the truck being the physical manifestation of the legend.
