FZ Shifter Joins America’s Trophy Series, Expanding Junior and Senior Gearbox Racing in 2026!
PHOENIX, AZ —
February 24, 2026 — FZ Shifter is proud to announce its official entry into the America’s Trophy series for the 2026 season. Introducing the
FZ85 Junior and
FZ125 Senior categories, this partnership brings high-performance shifter karting to one of the nation’s premier racing programs, running fully alongside the established Rotax Max Challenge (RMC) categories.
The action-packed series kicks off at the
Musselman Honda Circuit in Tucson, Arizona, on March 20-22. By joining the America’s Trophy schedule, FZ Shifter provides a strategic advantage for drivers, offering a high-level competitive platform to gain valuable track time and setup experience just one week prior to the SKUSA Pro Tour WinterNationals at the same venue.
"Our goal has always been to make shifter karting more accessible without sacrificing the 'Formula 1' feel that drivers crave," said Justin Stefani, FZ Shifter representative. "Joining the America’s Trophy series allows us to showcase the reliability and performance of the FZ platform on a national stage while providing a streamlined logistical solution for teams staying in Tucson for the SKUSA opener."
