Skunk2 Alpha Titanium Retainer Set – Honda D-Series High Performance Valvetrain Upgrade

Part Number: 308-05-1600

Product Description:

Upgrade your valvetrain with the Skunk2 Alpha Titanium Retainer Set, engineered specifically for Honda D-Series engines. Designed to significantly reduce valvetrain mass, these retainers help unlock additional horsepower while improving overall engine stability at high RPM.

Building on Skunk2’s proven Pro Series design, the Alpha retainers feature refined engineering enhancements such as radius-cut edges for increased rocker arm clearance, strategically placed lightening grooves, and a reduced overall height for improved valve seal clearance. The result is a lighter, stronger, and more efficient valvetrain component ideal for both street performance and race applications.

Each retainer is manufactured from medical-grade titanium, ultrasonically inspected, CNC machined, and individually serialized to ensure unmatched quality, traceability, and consistency. Designed using advanced 3D CAD and FEA analysis, and validated through real-world dyno and track testing, this kit delivers the reliability serious builds demand.
