Coil Over Spring 2.5in ID 8in Tall

The Coil Over Spring 2.5in ID 8in Tall from HYPERCO is a precision-engineered suspension component designed for serious vehicle builders and performance enthusiasts who demand consistent spring rates and reliable ride control. Whether you're developing a custom lowered build, upgrading a track car, or fine-tuning a street performance machine, this coil-over spring delivers the linear load progression necessary for predictable handling characteristics. The 2.5-inch inner diameter and 8-inch compressed height make this spring ideal for tight engine bay installations and modern coil-over shock assemblies where space and packaging efficiency are critical.

Built from high-quality steel and finished with a durable blue powder coat that resists corrosion and maintains aesthetic appeal under underbody exposure, this spring features a 425 lb/in spring rate—a moderate, versatile specification that balances comfort for street driving with sufficient stiffness for cornering support and load management. The consistent rate ensures predictable suspension geometry, reduced body roll, and improved tire contact patch consistency through dynamic driving conditions. At 3.34 lbs per unit, the spring contributes minimal unsprung weight while maintaining the structural integrity required for repeated compression and extension cycles over thousands of miles.

This spring is most commonly paired with adjustable coil-over shock absorbers in independent suspension systems on street rods, muscle cars, import tuners, and dedicated track vehicles. Installation requires removing the factory suspension and integrating the spring into a coil-over assembly with compatible dampers; proper setup includes ride height adjustment, corner balancing, and alignment verification to achieve optimal handling geometry. For builders seeking a reliable, intermediate spring rate suitable for mixed-use applications, the HYPERCO coil-over spring delivers proven performance without requiring specialized tuning knowledge or extreme modification budgets.
