The Skunk2 Pro Ti Retainer Set is engineered for Honda B16, B17, B18, H22, and F20B VTEC engines, offering a substantial upgrade in performance and reliability over factory steel retainers. Crafted from ultra-lightweight, medical-grade titanium, these retainers dramatically reduce valvetrain mass—improving throttle response, power delivery, and high-RPM stability.

Skunk2’s titanium retainers are 42% lighter than OEM steel retainers, helping to minimize valve float at high RPM while increasing durability under extreme conditions. Designed using 3D CAD modeling and Finite Element Analysis (FEA), each retainer is optimized for strength, clearance, and reduced height, ensuring perfect spring fitment and precise installed height.

Unlike generic alternatives, Skunk2’s Pro Ti Retainers feature radius-cut edges for improved rocker arm clearance, strategic lightening grooves, and a low-profile design that maintains proper valve seal clearance. Every retainer is CNC-machined, ultrasonically inspected, and serialized to guarantee flawless quality and traceability.

Perfect for high-performance street, drag, and circuit applications, these retainers pair seamlessly with Skunk2’s Alpha Series or Pro XP Valve Springs for the ultimate valvetrain stability.
