Skunk2 Steel Spring Base Kit – H-Series VTEC (H22A / F20B)

The Skunk2 Steel Spring Base Kit for Honda H22A and F20B engines enables H-style VTEC cylinder heads to utilize Skunk2’s high-performance Pro Series Valve Springs and Titanium Retainers originally developed for B-Series engines. This precision-engineered kit ensures perfect compatibility, reliability, and performance for high-revving VTEC applications.

Each spring base is developed using advanced 3D CAD modeling and Finite Element Analysis (FEA) to optimize strength, geometry, and long-term durability. Every design is rigorously dyno-tested and validated to meet the extreme demands of racing engines. Manufactured from ultrasonically inspected, certified high-strength steel, each base is CNC-machined to exact tolerances, then individually inspected to guarantee flawless fitment and performance.

Ideal for performance builders converting or upgrading H-series engines to run B-series valvetrain components, this kit ensures seamless compatibility and lasting strength under high-load conditions.
