Improve the reliability of your 2001-2016 GM 6.6L Duramax valvetrain with the Industrial Injection PDM-07184 Rocker Arm Spacer Kit. This kit addresses a potential weak point in the stock valvetrain design.
Key Features:
- Improved Reliability: By eliminating the factory valve springs between rockers, this kit prevents rocker arm shaft movement that can occur under high load or RPM conditions. This reduces wear on valves and rocker arms, promoting long-term engine reliability.
- Proper Rocker Arm Alignment: The spacers ensure proper rocker arm alignment during operation, optimizing engine performance and efficiency.
- Reduced Wear: Prevents irregular wear on valves and rocker arms caused by excessive movement.
