Power Driven 12v Street Conical Valve Spring Set

Power Driven Diesel presents this set of 12 high-performance drop-in valve springs for the 12v Cummins cylinder head. These lightweight valve spring assemblies are designed for maximum valve control up to 5,000 rpm, perfect for a hot street Cummins diesel. Springs feature 175 lbs. of seat pressure and 375 lbs. of open pressure. These street performance valve springs will accommodate the vast majority of street performance camshafts on the market while 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: Quantity 12 x conical valve springs, quantity 12 x chromoly steel retainers, and quantity 24 x 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.
