Designed for high rpm, BC & CryoHeat valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. Choose from the premium beehive design valve spring or the dual for those who perfer added pressure. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances. The titanium retainer option is only designed to work in race only applications with limited miles (under 2500 annually). BC H13 tool steel retainers are the correct choice for those looking to install the kit and forget about it for the rest of the engine's cycle life. Tool steel offers the ultimate in wear resistance. For those looking for an economical alternative, BC's 4140 chromoly steel retainers are the correct choice, but the wear characteristics are not as durable as the tool steel option.
