Part #: BC0130
Designed for high rpm, Brian Crower single valve springs for the Evolution X are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. Brian Crower titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances. An excellent product at a great price. We recommend using these stiffer valve springs and lighter retainers when upgrading cams.
