Beehive springs offer an assortment of benefits over stock-style cylindrical springs, including reduced valve spring mass, faster valve acceleration, increased valvetrain rigidity, and reduced valvetrain component stress among other benefits. Beehive springs are shaped like cylinders at the bottom and gradually taper and get smaller towards the top. These springs don’t require the extreme seat pressures needed with standard style valve springs. With lower seat pressures, valve train components—especially the pushrods, rockers, and lifters, are less stressed while performing the same work. Effectively Beehive springs can increase the engine’s upper rpm range over stock cylindrical springs.
