QA1 Chrome Coil-Over Spring 12in Length 2.5in ID 225lb/in Rate 12CS225

A proper coil-over spring is foundational to suspension performance—it controls weight transfer, maintains consistent ride height, and directly impacts handling precision. This QA1 chrome coil-over spring delivers a 225 lb/in rate in a compact 12-inch package, making it an ideal choice for hot rods, street rods, and classic builds where both performance and aesthetics matter. The chrome-plated finish provides show-quality appeal while the spring maintains QA1's strict manufacturing tolerances throughout its service life.

The 2.5-inch inside diameter makes this spring compatible with QA1 coil-over shocks and other standard coil-over systems using that specification. Installation is straightforward on any coil-over setup—simply compress and install. Whether you're fine-tuning suspension geometry on a weekend build or replacing a worn spring on a performance vehicle, this part delivers reliable spring rates without compromise.
