When you’re building a 6R80 to handle serious power, the input shaft is one of the first places to upgrade — and Bluestreak’s billet input shaft is built to take the hit. Made from premium 300M alloy and precision-crafted in Australia, this shaft is a direct replacement for the stock unit, requiring no machining or modification.

Designed to keep stock dimensions while drastically increasing strength, this is the piece you install when you don’t want to think twice about failures under load. Whether you’re on the drag strip with a transbrake or making big torque on the street, this shaft is proven to hold over 2,000 horsepower without flinching.

Features:

  • Made from high-grade 300M alloy

  • CNC-indexed splines for perfect engagement

  • Double tempered and shot peened for extreme durability

  • Precision ground for tight tolerances

  • Drop-in fit — no machining required

  • Proudly made in Australia

Works on all 2015-2017 Mustang 6R80 transmissions
