Pac Racing Springs RPM Beehive Valve Springs The latest technology available. By reducing the top coil of the spring it allows for a reduced mass retainer. Additionally, beehives offer a multi-arc (Ovate) that allows for the stress distribution of the wire to be equally distributed on the opposing sides of the wire. Combine these features and the result is a variable frequency spring that performs at a higher level RPM over traditional springs. Premium RPM processing and higher loads to withstand the vigors of street and strip use.
