The Hamilton 103LB Valve Springs increase the overall seat pressure to ensure proper function of the engines valve-train, preventing any loss in performance or reliability of the engine. The factory valve springs are not designed to withstand the added pressure's or RPM's associated with performance modifications and can quickly become compromised anytime you increase your engines boost, drivepressure or RPM.
These valve springs were carefully designed with a lower "nose pressure" to minimize wear and tear on the camshaft, making these a perfect option for most mild to moderate applications.
