PAC Racing Beehive Series Valve Springs

PAC Racing Beehive Series valve springs combine the latest technologies available to produce the best performing springs on the market. Reducing the top coil of the springs allows for a reduced mass retainer. Additionally, beehive springs offer a multi-arc (ovate or egg-shaped) 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 than traditional springs.
