Coil Over Spring 2.5in ID 14in Tall

The Coil Over Spring 2.5in ID 14in Tall by HYPERCO is a purpose-built suspension component designed for automotive enthusiasts and professional tuners who demand precise ride height control and consistent spring rates. This coil-over spring serves as the backbone of any modern coil-over suspension system, delivering the adjustability and performance required for everything from street cars and track day vehicles to full competition builds. Whether you're lowering your ride for aesthetics or engineering a dedicated performance setup, this spring provides the engineering foundation that separates bolt-on upgrades from true suspension mastery.

Engineered with a 2.5-inch inner diameter and 14-inch overall length, this HYPERCO spring features a linear 200 lb/in spring rate, meaning it compresses approximately 0.5 inches under every 100 pounds of load—ideal for calculating suspension geometry and predicting vehicle behavior under cornering loads. The steel construction provides consistent, predictable spring behavior across wide temperature ranges, while the blue powder coat finish protects against corrosion and road salt while maintaining a professional appearance. At 5.16 lbs per spring, the lightweight construction minimizes unsprung weight, a critical factor in suspension tuning where every pound counts toward response time and handling precision.

This coil-over spring is best suited for dedicated suspension builders pairing it with matching dampers and mounting hardware as part of a complete coil-over kit or custom suspension assembly. The 200 lb/in rate works well for street and mild track applications on vehicles in the 2,800–3,500 lb range per corner, making it popular among sport compact and lightweight sports car builds. Installation requires proper suspension geometry knowledge and precision measurement to ensure correct ride height and spring preload; always pair with quality dampers matched to this spring rate for optimal control. Verify inner diameter clearance and available coil-over body lengths before ordering to guarantee compatibility with your chosen damper package.
