Construction & Design

Each valve spring in this kit is crafted from premium spring steel, heat-treated to withstand the rigors of high-performance operation. The beehive shape tapers the spring diameter, reducing mass at the top end of the spring. This design minimizes inertia in the valvetrain, allowing for quicker valve response and reducing the risk of valve float during aggressive driving or racing conditions.

Supertech’s precision manufacturing process ensures each spring maintains consistent tension and durability over extended use. The springs are engineered to meet strict OEM specifications while providing enhanced performance characteristics, making them a reliable upgrade for both street and track applications.
