Hardened Steel Hub

Upgrade Option Specific Steps & Procedures

**Performance Modification Protocols can Deviate Based on Individual Situations**

• Hub Forging

  Forge an impeller hub from high-grade steel.

  An impeller hub is forged from premium steel, creating a dense, robust component that resists deformation. This forging process enhances strength compared to standard hubs. PNH’s expertise ensures the hub delivers superior durability and reliable torque transfer.

• Heat Treatment Application

  Heat-treat the hub to the appropriate material hardness.

  The forged hub undergoes heat treatment to achieve an acceptable Rockwell hardness. This significantly increasing its strength and wear resistance. This process hardens the steel, preventing damage under high torque. The treated hub enhances longevity and performance reliability.

• Precision Spline Machining

  Machine hub splines for exact fitment.

  Hub splines are CNC-machined to precise tolerances, ensuring perfect fitment with the torque converter’s components. This accuracy minimizes vibration and wear. PNH’s machining process guarantees smooth engagement and efficient power transfer, boosting overall durability.

• Durability and Performance Testing

  Test the hub for strength and reliability.

  The hardened hub is tested under simulated high-torque conditions to verify strength and durability. This quality control confirms resistance to wear and deformation. The testing ensures enhanced reliability and performance.
