Description

Product Description: nnIncrease the performance of your 1998.5-2018 Dodge 5.9L/6.7L Cummins with the Hamilton Cams Valve Springs.  The stock springs have 78-82lbs of pressure on average at 1.380″.  If you have over 50psi (boost or drive pressure) and 3,800 rpm, stock springs do not fully control the valvetrain.  This allows a few negative things to happen.  First, valve float, which can cause serious damage to the valvetrain.  Second, the 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 reintroduced into the cylinder shield the fuel particles from oxygen in the cylinder.nnThis does a few things that negatively affect power. It increases the time delay from the start of injection to the 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.nnHamilton Cams suggests these springs if you are over 50lbs of boost (or drive pressure) or over 3800 rpm or when running aftermarket camshafts.  Hamilton has slightly lowered the pressure on the springs from 110# to 103#.  If you are running over 4,500 rpm with a large cam, they suggest going with 103# springs with different processing for better longevity in extreme applications as well as their lightweight 4130 or titanium retainers.  Retainers are not included.nn nnFits:n
