The mission was to design the ultimate off-road transaxle that could handle over 1000 hp with 40” tires in a 6000-pound open-wheel vehicle. This all-new gearbox design for 2019 takes the race-winning proven design of the FRS5 and adds strength across the board. Raising the bar to the next level, this is the strongest transaxle period.
