4.92 - 14x69 Final Drive for Mitsubishi Lancer EVO 5 speed gearbox

Final Drive for Mitsubishi Lancer EVO – 5-Speed Gearbox

Available Ratio:

• 4.92 – 14/69

Material:

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

Hardness:

• HRC 56–60, ensuring superior wear resistance and surface fatigue strength, even in demanding motorsport applications.

Surface Treatments:

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

• Sandblasting – Provides a 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 strength, dimensional stability, and longevity, the following heat treatments are applied:

• Carburizing – Produces a hard, wear-resistant surface while maintaining a tough and ductile core

• Cryogenic treatment – Improves wear resistance, dimensional stability, and long-term gear mesh performance

Performance Benefits:

• Increased torque multiplication and improved acceleration

• Designed specifically for Mitsubishi Lancer EVO 5-speed gearboxes

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

• Ideal for motorsport and high-performance street use
