As horsepower gets easier and cheaper to make and racers set the bar higher and higher, a need is created for numerically lower gear sets with higher strength requirements. Today’s high HP racer needs a durable transmission with a less aggressive starting line ratio. Most racers achieve this by converting the Turbo 400 transmission to a 2-speed unit allowing them the ability to leave off the transbrake in 2nd gear. ATI now has an answer for this market and offers three variations of a 2-speed Turbo 400! OEM cased units are rated to 1800 HP and not intended for heavy weight cars. ATI SuperCase recommended over 2000 HP!

*Optional HD 300M output shaft recommended for vehicles over 3,000 lbs (with BBC) or 3,200 lbs (with SBC)
