FTI Performance Powerglide 300M High-Flow Input Shaft – Turbo Spline

If you’re pushing real power through a Powerglide, the input shaft becomes a liability fast.

This FTI Performance 300M high-flow input shaft is built to handle extreme horsepower and torque, while improving internal lubrication through its high-flow design.

Designed with a turbo spline configuration, this shaft provides increased strength and reliability for demanding drag racing applications where stock components simply won’t survive.

Key Features

  • Genuine FTI Performance component
  • Fits GM Powerglide transmissions
  • 300M alloy steel construction for superior strength
  • High-flow design improves internal lubrication
  • Turbo spline configuration for increased durability
  • Built for high horsepower and racing applications

Why Upgrade to a 300M Input Shaft?

Stock shafts fail when:

  • Torque levels increase
  • Shock load from launches spikes
  • Fluiding and lubrication become critical

This upgraded shaft helps:

  • Handle extreme load without twisting or breaking
  • Improve lubrication to critical components
  • Increase overall transmission reliability

Because when an input shaft fails… it usually takes other expensive parts with it.

Built for Serious Power

  • Drag racing builds
  • High horsepower street/strip cars
  • Turbocharged and nitrous applications
  • Competition Powerglide transmissions

⚠️ Important Notes

  • Designed for Powerglide transmissions only
  • Turbo spline configuration – verify compatibility before purchase
  • Intended for performance and racing applications
