FTI Performance TH400 Short Output Shaft – Steel

If you’re running power through a TH400, the output shaft is one of the first things to complain… or fail.

This FTI Performance short output shaft is built from durable steel construction, designed to handle the demands of performance builds and racing applications where stock components may not hold up.

Whether you're replacing a worn shaft or upgrading during a rebuild, this component helps ensure reliable power transfer and long-term durability.

Key Features

  • Genuine FTI Performance component
  • Fits GM TH400 transmissions
  • Short output shaft configuration
  • Steel construction for strength and durability
  • Designed for performance and rebuild applications

Why the Output Shaft Matters

The output shaft handles:

  • Torque transfer to the driveshaft
  • Load from acceleration and traction
  • Stress from hard launches

If it fails:

  • Power doesn’t go anywhere
  • Internal damage can follow
  • And you’re pulling the transmission again

Built for Performance

  • Drag racing TH400 builds
  • Street/strip performance vehicles
  • Transmission rebuilds and upgrades
  • Custom driveline setups

⚠️ Important Notes

  • Designed for TH400 transmissions only
  • Short shaft configuration – verify compatibility
  • Intended for performance and racing use
