Ferrea has been manufacturing hardcore racing valvetrain components for nearly 50 years, and their Pro-Series titanium retainers represent the pinnacle of valvetrain technology. The lightweight titanium construction reduces reciprocating mass, allowing for higher RPM operation while maintaining superior strength and stability. These retainers are ideal for engine builders seeking maximum performance and reliability in high-performance street or race applications.

Note: Sold individually. Complete VR38DETT valve spring kits typically require 12 exhaust retainers (E11110) and 12 intake retainers (E11107).
