Machined Forged Apply Piston

Upgrade Option Specific Steps & Procedures

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

• Forged Piston Replacement

  Replace stock piston with a high-strength forged steel piston for enhanced durability.

  The stock apply piston, often a weaker cast or stamped component, is replaced with a high-strength forged steel piston. Forging involves shaping premium steel under intense pressure, creating a denser, more durable structure. This upgrade, performed by PNH, significantly enhances the piston’s ability to withstand high torque and stress, preventing deformation and ensuring long-term reliability in high-performance applications like racing or towing.

• Precision CNC Machining

  CNC-machine the forged piston to precise tolerances for perfect fitment.

  The forged steel piston is CNC-machined to precise dimensions using advanced computer-controlled equipment. This accuracy ensures a perfect fit within the torque converter’s lockup clutch assembly, minimizing misalignment and vibration. PNH’s meticulous machining process guarantees smooth operation and consistent clutch engagement, critical for maintaining performance under the extreme demands of modified engines or aggressive driving conditions.

• Surface Finish Optimization

  Optimize surface finish to improve clutch plate engagement and friction material bonding.

  The piston’s surface is finely tuned through precision machining to optimize clutch plate engagement and friction material bonding. A smooth, consistent finish enhances grip between the piston and clutch plates, improving lockup efficiency. PNH’s expertise ensures the surface promotes strong adhesion of high-performance friction materials, reducing slippage and boosting power transfer in demanding scenarios like drag racing.

• Torque Capacity Enhancement

  Increase torque capacity to handle high-performance engine demands.

  By using a forged, high-strength piston, the upgrade increases the torque converter’s ability to handle higher torque loads. This allows the lockup clutch to manage the power output of modified engines, such as those with superchargers or turbochargers. PNH’s design ensures reliable power transfer to the drivetrain, enhancing acceleration and performance in high-horsepower vehicles without compromising clutch integrity.

• Heat Resistance Improvement

  Enhance heat resistance to prevent warping under extreme conditions.

  The forged steel piston is engineered to resist warping under high temperatures, a common issue in performance driving. Its robust material properties and heat-treated construction maintain structural integrity during extreme conditions. PNH’s upgrade ensures the piston performs reliably under prolonged stress, extending the torque converter’s lifespan and maintaining consistent clutch engagement in high-heat environments like racing or heavy-duty use.
