Available Ratios

• 4.785 – 14/67
• 5.167 – 12/62

Material

Manufactured from billet and forged Ni-Cr-Mo steel, offering exceptional mechanical strength, high impact resistance, and long-term durability under high torque and aggressive driving conditions.

Hardness

HRC 56–60, ensuring excellent resistance to wear and surface fatigue, even in demanding motorsport applications.

Surface Treatments

Multiple advanced surface treatments are applied to maximize durability and reliability:

• Sandblasting – Ensures a uniform surface finish and optimal preparation
• Shot peening – Increases fatigue strength by inducing compressive surface stresses
• WPC treatment (optional) – Enhances surface hardness, reduces friction, and improves micro-surface durability

Heat Treatments

To achieve maximum strength, dimensional stability, and service life:

• Carburizing – Produces a hard, wear-resistant surface while maintaining a tough core
• Cryogenic treatment (optional) – Improves dimensional stability, wear resistance, and long-term gear mesh performance

Performance Benefits

• Increased torque multiplication and improved acceleration
• High resistance to shock loads and sustained high-RPM operation
