The Manley Nextek Dual Race Valve Springs feature a unique design that utilizes a dual-race design for the valve stems.

These valve springs are available in a range of spring rates to suit various engine applications. The specific spring rates for your engine application can be determined by consulting the Manley catalog or contacting their technical support team.
