4.33 - 15x65 Final Drive for Opel F18 / F20 gearbox

Final Drive for Opel F18 / F20 Gearbox

Available Ratio:

• 4.33 – 15/65

Material:

Manufactured from billet and forged Ni-Cr-Mo steel, providing outstanding mechanical strength, high impact resistance, and long-term durability under extreme torque loads.

Hardness:

• HRC 56–60, ensuring excellent wear resistance and surface fatigue strength, even in high-performance and motorsport applications.

Surface Treatments:

Multiple advanced surface treatment processes are applied to maximize durability and reliability:

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

Heat Treatments:

To achieve maximum structural integrity and performance, the following heat treatments are used:

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

Performance Benefits:

• Increased torque multiplication and improved acceleration
• Designed for Opel F18 and F20 gearboxes
• High resistance to shock loads and sustained high-RPM operation
• Ideal for motorsport and high-performance street use
