HAMILTON CAMS TOOL STEEL RETAINERS 07-S-004 | 1998.5-2018 CUMMINS 5.9L/6.7L

The Hamilton Cams 07-S-004 Tool Steel Retainers are designed to complement upgraded valvetrain components in 1998.5–2018 Dodge Ram trucks equipped with the 5.9L or 6.7L Cummins diesel engine. These retainers are engineered to work specifically with Hamilton valve springs, providing improved durability and stability in high-performance diesel applications.

Manufactured from high-strength tool steel, these retainers offer excellent resistance to wear and fatigue while maintaining an ultra-lightweight design. Reducing valvetrain mass helps improve valve control at higher engine speeds, making these retainers ideal for performance builds operating at elevated RPM levels.

The Hamilton 07-S-004 retainers are well-suited for engines running over 4,500 RPM and camshafts with more than .320-inch lobe lift. Their durable construction and lightweight design help maintain consistent valve operation in demanding diesel performance environments.
