Description
If you’re building a coil-over suspension setup, spring rate is everything—and the QA1 C/O Spring delivers a solid 450 lb/in rate that hits the sweet spot for street and entry-level track applications. This 12-inch spring compresses and extends with predictable linearity, giving you the control you need without excessive harshness. The silver powder coat protects against corrosion while maintaining a clean appearance in engine bays or suspension galleries.
