Few years ago, in one of my articles, I called them Brothers in Ultra4 because the bond between Rob Butler and Levi Shirley goes beyond friendship and team spirit. Rob supported Levi in Europe and Shirley helped Butler in the States.

This year at the King of the Hammers the roads of these two extraordinary drivers will once again unite to compete in the UTV class. Robert Butler will drive the Polaris RZR Turbo S Velocity, purchased by 2-time “king” Mitch Guthrie, and Levi Shirley will take on the role of co-pilot.

Robert Butler bios

Rob Butler and his highly experienced crew are one of Europe’s top Ultra4 offroad race teams and Ultra4 vehicle builder. Since 2012 Rob Has placed highly at Ultra4 races in both Europe and the USA gaining many podiums, consisten regular 1st place qualifier, fastest lap awards and night stage wins. Robert Butler raced twice at King of the Hammers: 2015 and 2016. In 2015 he drove Layla Levi Shirley's old vehicle but got fought in a huge bottleneck at Sledghammer and ran out of time as a result. In 2016 he shipped his own mid engine Eurofighter (solid axle) to the Lakebed and he completed the race in time placing 23rd... only like 35 cars finished the race. Rob is still the only European driver ever to compete and finish King of the Hammers in a European built Ultra4 vehicle (his Off-Road Armoury built solid axel Eurofighter).

Levi Shirley bios

Levi Shirley was named the Ultra4 Sportsman of the Year 2011 and 2014. The title is a huge honor, as fellow drivers in Ultra4 vote on this title. In 2015, Levi proved himself a top contender by taking 3rd place at the toughest off-road race in North America, King of the Hammers in Johnson Valley, CA. He followed this huge accomplishment with an incredible race season of five top-ten finishes. He then ended the 2015 season with the Ultra4 National Championship. In 2017, Levi had five podium finishes, and became the Ultra4 West Coast Series Champion and runner up in the 2017 Ultra4 National Championship. Levi is also well known in the Ultra4 Europe community. He was the first American driver to race in the Ultra4 European Series. Levi became a triple threat after taking three titles in the 2014 Ultra4 Europe Series: King of the Mountains in Italy, King of the Valleys in Wales, and King of Portugal.
