Overview

To make big power, you run an aggressive cam profile with high lift.To maintain control of the valve train, the valve spring needs to provide adequate seat and nose pressure, and be able to last a reasonable life cycle in a sometimes brutal environment. In today’s performance engines, this is one of the most highly stressed components; for this reason, you should only consider the highest quality spring you can buy.
