  • Stage 0

    This stage is designed for daily drivers or time attack-style vehicles that require a power-capable and reliable transmission, but don't need to launch aggressively or push the limits in second gear. It features upgraded and revised clutch packs, allowing you to maximize the potential of your build without the concern of reliability.

  • Stage 1

    Ready for both the streets and the drag strip on the weekends, this stage is designed to handle aggressive launches and hard acceleration while maintaining smooth shifting and reliability. It's the ideal build for stock motor cars looking to push their limits without compromising performance.

  • Stage 2

    Do you have a built motor and ready to push the limits of your setup, this stage has you covered. It maintains smooth, stock-like shifts while ensuring your transmission can handle nearly anything you throw at it.

  • Stage 3

    The strongest build for the cars ready to try and set records but ensure your transmission is going to stay strong throughout the race season.

All ratings are wheel horsepower and wheel torque and are based off our testing. They are not guaranteed and will vary depending on abuse, lack of care, and maintenance. Stage 0 is meant for street car applications due to the fact it retains your stock cast E hub and can break during abrasive driving in 2nd gear.
