Final Drive for Honda D15B / D16A9 for cable clutch kit release

Available Ratios:

• 4.92 – 14/69

Material:

Manufactured from billet and forged Ni-Cr-Mo steel, delivering 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 motorsport and high-performance street applications.

Surface Treatments:

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

• Sandblasting – Ensures a 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 longevity, the following heat treatments are applied:

• Carburizing – Produces a hard, wear-resistant surface while maintaining a tough 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 Honda D15B / D16A9 gearboxes

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

• Suitable for motorsport and high-performance street use
