Billet Main Shaft | ZF 8HP70 / 8HP75 / 8HP76 Transmission

The ATS Billet Main Shaft is engineered for the ZF 8HP70, 8HP75, and 8HP76 transmissions, delivering the strength and reliability needed for high-horsepower street cars, drag racing applications, and extreme-duty builds where factory components can become a limitation.

Precision-machined from premium alloy steel, each shaft undergoes heat treatment and hardening processes to maximize strength, durability, and resistance to torsional fatigue under extreme loads.

Designed as a direct upgrade over the OEM main shaft, the ATS billet design incorporates reinforced geometry to withstand hard launches, increased torque, aggressive shifting, and repeated abuse in performance applications.

Whether you’re building a boosted street car, drag car, roll racing setup, or full race vehicle, this upgrade is built to help push the ZF 8HP platform to the next level.

Features:

• Precision-machined billet alloy steel construction
• Heat-treated and hardened for maximum durability
• Increased torsional strength over OEM shaft
• Reinforced geometry for extreme power applications
• Designed for hard launches and aggressive driving
• Ideal for drag racing, roll racing, and high-horsepower street builds
• Direct fit for ZF 8HP70, 8HP75, and 8HP76 transmissions

At Applied Torque Solutions, every component is developed with one goal in mind: advancing the ZF 8HP platform beyond factory limits.
