Description
If you’re building a coil-over suspension system, spring rate directly impacts your vehicle’s handling balance, ride height control, and overall chassis dynamics. This QA1 spring delivers a solid 350 lb/in rate—stiff enough for performance driving without being so aggressive that it compromises street manners. The 2.5-inch inner diameter and 14-inch length make this a go-to choice for many custom suspension applications where precision tuning matters.
