Description
Valve spring retainers are critical to maintaining proper spring seat pressure and preventing valve float under aggressive engine conditions. Manley’s titanium construction reduces rotating mass in the cylinder head, allowing higher RPM capability and more consistent valve timing throughout your powerband. These 10-degree retainers are engineered for dual-spring applications and deliver the precision fitment and durability expected in serious racing and high-performance builds.
