Valve Spring Locator

Skunk2's high-quality Spring Bases for Honda's K-series engines are designed to allow any K-series cylinder head originally equipped with single valve springs to accept higher-performance, dual valve springs, like those from Skunk2. Each Spring Base is manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to make sure the design is optimized for strength and longevity. Engineers then test and prove the design on the engine dyno. Once approved for manufacturing, engineers make sure to only use high-quality steel that's been ultrasonically inspected and certified. After CNC machining, each Spring Base is then individually inspected to ensure proper dimensions and that it's free from machining defects. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality and remain standard-issue on each Skunk2 vehicle that we build and support.
