Manley Dual Valvesprings and Ti Retainers 4G63 4G63T DSM

This is a set of 16 Manley single wound Valvesprings and Titanium Retainers for Mitusbishi 4G63 Engines commonly found in the Eclipse GST GSX, and many other 4g63 powered vehicles.

Manley is known for their superior quality in manufacturing. These springs are wound from super clean chrome silicon high tensile strength steel alloy, and are heat treated and shot peened to ensure long service life in applications featuring high lift cams. These valvesprings are specifically designed to live in the extreme conditions of a race engine reving at high rpm with high lift cams.

Manley's lightweight titanium retainers decrease the amount of mass at the end of the spring, allowing you to rev higher while avoiding dangerous valve float conditions.
