Material:
Manufactured from billet and forged Ni-Cr-Mo steel, providing exceptional mechanical strength, high impact resistance, and long-term durability under extreme torque loads.
Hardness:
HRC 56–60, ensuring excellent resistance to wear and surface fatigue, even under high torque and aggressive driving conditions.
Surface Treatments:
The final drive components undergo multiple advanced surface treatment processes to maximize performance and service life:
Sandblasting – Improves surface uniformity and preparation
Shot peening – Increases fatigue strength by inducing compressive surface stresses
WPC treatment – Enhances surface hardness, reduces friction, and improves micro-surface durability
Heat Treatments:
To ensure maximum strength, stability, and reliability, the following heat treatments are applied:
Carburizing – Increases surface hardness while maintaining a tough, impact-resistant core
Cryogenic treatment – Improves dimensional stability, wear resistance, and long-term gear mesh durability
Performance Benefits:
Increased torque multiplication and improved acceleration
Optimized for motorsport and high-performance street applications
High resistance to shock loads and sustained high-speed operation
Specifically designed for PSA MA gearboxes using circlip + threaded fixation systems
