Hyperco Coil Over Spring 2.5in ID 12in Tall 1812B0400

A properly tuned coil-over spring is fundamental to suspension geometry and handling precision—this Hyperco unit delivers predictable, linear spring rates essential for dialing in your setup on track or at the strip. At 400 lb/in, this spring hits the sweet spot for road racing and autocross applications, providing enough compliance for bump absorption while maintaining the control needed for aggressive driving. The 12-inch length and 2.5-inch ID fit standard coil-over shock bodies, making this a direct bolt-in solution for builds where suspension tuning is non-negotiable.
