Kit provides everything you need to do your push rods and valve springs on 24V Cummins.If you are over 750hp, the cylinder pressures acting on the valve can bend your OEM pushrods before the valve opens. This can retard cam timing and reduce valve lift These pushrods are a 3 piece design that features 12mm diameter .120″ wall, which is much thicker than the OEM 3/8 or other performance shops 7/16″ Diameter.
If you are over 35 PSI (boost or drive pressure) and 3,800 RPM, we suggest going with Hamilton Cams 103lb springs with heat treat and shot peen, for better longevity in extreme applications. Hamilton Cams springs at 103 lb spring pressure and 180 lb nose pressure are better than stock which can cause valve float and reversion.
