Description

The Manley Performance 22408-16 is a set of dual valve springs designed for high-performance street applications and long service life. These springs are manufactured from high-tensile Chrome Silicon steel wire and are shot-peened to MIL spec for maximum fatigue life. Manley's proprietary multi-step heat treating process minimizes load loss, and computer-aided design reduces valve bounce and valve gear separation.
