Designed for the increased duties of aftermarket camshafts and increased rpm operation. We've sourced springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy. The included titanium retainers put your valvetrain on a diet with a weight reduction. On parts that change direction quickly, this goes a long way!
