- Bimetallic Construction: Features a mid-stem weld that joins a premium-grade austenitic stainless steel valve head (EV16) to a high-grade, high-chromium steel stem (HNV3), optimizing the valve for both heat resistance and structural integrity.
- Advanced Nitriding Treatment: The entire surface is nitrided and precision polished, a process that significantly reduces friction within the valve guide and enhances fatigue resistance against repetitive high-RPM cycles.
- Enhanced Tip Hardness: The valve tip is hardened to a minimum of 50 HRC (Rockwell Hardness Scale), providing a robust contact surface that resists mushrooming and wear under heavy valvetrain loads.
- Superior Material Composition: The use of HNV3 steel for the stem provides the necessary wear resistance to extend service life, while the EV16 head offers the thermal stability required for the demanding environment of a Cummins combustion chamber.
- Warranty and Fitment: Specifically engineered for the 5.9L and 6.7L Cummins platforms and backed by a 1-year limited manufacturer warranty.
- Wafer: N
- Length: 4.907
- Stem Type: 1G
- Nitride Finish
- Seat Angle: 30
- Tip Length: 0.2990
- Head Diameter: 1.299
- Stem Diameter: 0.2756
The SBI 02014R Performance Intake Valve represents a critical upgrade for the 1998.5–2024 Dodge Ram 5.9L and 6.7L Cummins engines. In high-performance diesel applications, the intake valve is subjected to extreme thermal cycling and mechanical stress that can lead to premature wear or catastrophic failure in standard components. To combat this, SBI utilizes a sophisticated bimetallic construction. By employing specialized manufacturing processes, this valve offers a significant leap in durability over stock units, ensuring that your valvetrain can handle the increased pressures of modern performance tuning while maintaining long-term reliability.
