Construction & Design

The AST Suspension Linear Coilover Springs are meticulously crafted from premium chrome silicon wire, a material renowned for its excellent tensile strength and fatigue life. The springs are coiled on state-of-the-art Wafios compression coiling machines, which ensure tight tolerances and uniformity in every spring produced. This precision manufacturing process results in a reliable, high-performance spring that maintains consistent characteristics throughout its lifespan.

The springs feature a linear rate, meaning the force required to compress them remains constant regardless of the amount of compression. This design provides a predictable and linear response, making it easier to tune your suspension for optimal handling and comfort. The springs are pre-blocked, which helps prevent unwanted movement or settling, and are protected against corrosion to withstand harsh driving conditions and exposure to the elements.
