Hamilton Cams Valve Springs

Product Name: Valve Springs
Manufacturer: Hamilton Cams
Application: Most Diesels

If you are running more boost, drive pressure, or more rpm than OEM, stock springs do not fully control the valve train. This allows a few negative things to happen. First, valve float, which can cause serious damage to the valve train by allowing the valves to close at a higher velocity as opposed to closing at the rate the cam dictates. Second, intake and exhaust valves can be blown open by boost and exhaust drive pressure which allows reversion. Reversion can hurt your power potential by allowing exhaust gasses to enter the cylinder on the intake stroke. Inert gasses in the exhaust, when re-introduced into the cylinder shield the fuel particles from oxygen in the cylinder. This does a few things that negatively affect power. It increases the time delay from start of injection to start of combustion, it decreases the maximum pressure and maximum temperature reached in the cylinder and it increases the total time needed to completely burn the available fuel. Correct valve spring pressure is a very important piece of power production. Hamilton Cams designs high-performance valve springs for diesel truck owners seeking to harness the most power, torque, fuel mileage and pulling strength for their truck.
