Designed for high rpm, BC 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.

BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances. BC recommends using titanium retainers on dual springs ONLY if limited street use (less than 7000 miles per year). Although titanium is approximately 40% lighter, and is perceived as stronger than steel, it will wear over time on a dual spring setup.
