Hamilton Cams 07-S-001 12-Valve 155 lb Valve Springs
The Hamilton Cams 07-S-001 12-Valve 155 lb Valve Springs are engineered to enhance the valvetrain performance of 1989-1998 Dodge Cummins 5.9L 12-valve engines. These springs provide increased seat pressure to prevent valve float and reversion, ensuring optimal engine efficiency under high boost and elevated RPM conditions.
Detailed Product Description
Increased Seat Pressure
Stock 12-valve springs typically offer lower seat pressures, which may be insufficient under high-performance conditions. The Hamilton Cams 07-S-001 springs provide a seat pressure of 165 lbs, effectively controlling the valvetrain at boost pressures over 30 psi and engine speeds exceeding 3,500 RPM.
Prevention of Valve Float and Reversion
By providing higher seat pressure, these springs prevent valve float, which can cause significant valvetrain damage. They also mitigate reversion—the unwanted entry of exhaust gases into the cylinder during the intake stroke—thereby maintaining combustion efficiency and power output.
Conical Spring Design
The springs feature a conical design, which enhances valvetrain stability and allows for higher RPM operation without compromising durability.
Compatibility and Installation
These valve springs are compatible with 1989-1998 Dodge Cummins 5.9L 12-valve engines. They are suitable for applications involving high boost pressures, elevated RPMs, or aftermarket camshafts. The kit includes retainers and 10-degree locks for secure installation.
