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. 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.

Important Notes: Only for use on K-series engines originally equipped with single valve springs that are upgrading to dual valve springs. .440-inch inner diameter. Note: If this product is drop shipping from Skunk2 directly, it takes 3 business days to process the order prior to shipping.
