FORTIN FRS5 4.0 SEQUENTIAL
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.

FRS5 SEQUENTIAL
Fortin Racing developed and converted the first Hewland Transaxle, originally designed for Formula and Indy Car racing, for off-road desert racing in 1971. The Hewland DG 300 with Fortin modifications quickly became the off-road racing industry leader as it allowed unlimited class teams to increase their engine size to 3.2 litre.
In the early 1980’s Fortin Racing began developing the Fortin 5spd. The Fortin Transaxle has continued to evolve to meet the demands of off-road racing, desert rally racing, endurance road course racing and drag racing around the world. The transaxle is currently running up to 700 Hp in off-road racing, over 1000 Hp in recreational vehicles and over 1100 Hp in front-wheel-drive drag race cars. The new off-road desert and short course truck gearboxes are currently being run with over 800 Hp. The most recent Fortin Transaxle wins include the 2007 Dakar Rally, the 2008 BITD Terrible Town 250, the 2008 SCORE Baja 500, the 2008 SCORE Baja 1000 and the 2008 BITD Vegas to Reno. McDowell Motorsports recently won the 2008 BITD points championship and “The King of The Desert” award for fastest mile per hour average among all classes for the entire season using the FRS5 transaxle.
The original Fortin 5 speed has evolved during the past 20 years into a complete line up of gearboxes including 4 and 5 speed “H” pattern gearboxes and 4, 5 and 6 speed sequential gearboxes. No matter what your application is we can match you with the right gearbox.
