Description
If you’re building or tuning a coil-over suspension system, spring rate consistency is non-negotiable—and this QA1 unit delivers the predictable 350 lb/in response your chassis needs for precise handling and repeatable performance. The 2.5-inch ID and 12-inch length make it a direct fit for most aftermarket coil-over kits, eliminating guesswork during installation. Backed by QA1’s reputation for quality manufacturing, this spring will maintain its rate under sustained track use without degradation.
