Billet Main Shaft | ZF 8HP45 / 8HP50 / 8HP51 Transmissions

The ATS Billet Main Shaft is engineered for ZF 8HP45, 8HP50, and 8HP51 transmissions operating in high-performance, high-horsepower, and extreme-duty environments where factory components can become a limiting factor.

Precision-machined from premium alloy steel, each shaft undergoes heat treatment and hardening processes to deliver exceptional strength, increased durability, and superior resistance to torsional fatigue under demanding conditions.

Designed as a direct replacement for the OEM main shaft, the ATS billet design incorporates reinforced geometry to better withstand increased torque loads, aggressive launches, drag racing conditions, and hard street use.

Whether you are building a boosted street car, drift application, drag vehicle, or dedicated race setup, the ATS Billet Main Shaft provides the strength and reliability needed to push the limits of the ZF 8HP platform.

Features:

• Fits ZF 8HP45, 8HP50, and 8HP51 transmissions
• Precision-machined billet alloy steel construction
• Heat-treated and hardened for maximum durability
• Increased resistance to torsional fatigue and shaft failure
• Reinforced design for high-horsepower applications
