Howards Cams Electro Polished Valve Springs
The unique design of the inverted conical valve spring offers increased harmonic resistance for greater spring stability. This design requires less spring pressure for better valve control. Manufactured of aircraft-grade chrome silicone with advanced heat-treating. Springs then receive an advanced electro polished finish and stress relieved. This enhanced finish increases valve spring life and fatigue resistance for lap after lap consistency. Designed for racing hydraulic and mechanical flat tappet as well as performance hydraulic roller camshafts. Sets of 16.
