Description
Power Driven Diesel | 12v Street Conical Valve Spring Set
Set of 12 high performance drop-in valve springs for the 12v Cummins cylinder head.
These light-weight valve spring assemblies are designed for maximum valve control up to 5000 RPM, perfect for a hot street Cummins diesel.
Springs feature 175 lbs of seat pressure, and 375 lbs open pressure.
These street performance valve springs will accommodate the vast majority of performance street camshafts on the market while still maintaining reasonable open pressure for cam lobe and lifter/tappet life.
As with any aftermarket valve spring upgrade with higher than stock pressure, it’s recommended that a higher quality engine oil is used to protect the cam and tappets.
Kit contains: 12 conical valve springs, 12 chromoly steel retainers, 24 lock halves (enough for 12 valves)
These street conical springs, retainers, and locks are designed to drop-in at a 1.950″ installed height and 175 lbs of seat pressure.
