5.31 - 13X69 Final Drive for Renault Megane 3 PK4 gearbox

Final Drive for Renault Mégane III

PK4 Gearbox

Available Ratio:

• 5.31 – 13/69

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 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 treatment processes are applied to maximize durability and reliability:

• Sandblasting – Ensures uniform surface finish and optimal surface 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 achieve maximum strength, dimensional stability, and service life, the following heat treatments are applied:

• Carburizing – Produces 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 significantly improved acceleration

• Designed specifically for Renault Mégane III PK4 gearboxes

• High resistance to shock loads and sustained high-RPM operation

• Suitable for motorsport and high-performance street use
