QA1 Chrome Coil-Over Spring 10in 2.5in ID 250lb/in 10CS250

A quality coil-over spring is fundamental to suspension geometry and ride quality—get this wrong, and you'll compromise handling, comfort, and component longevity. The QA1 10CS250 delivers a precisely-rated 250 lb/in spring constant in a compact 10-inch package, making it an ideal choice for classic hot rods and street rods where space and aesthetics matter equally. The chrome-plated finish isn't just for show; it protects against corrosion while delivering the polished look that separates a show-quality build from the rest.

This spring fits QA1 coil-over shocks and any standard 2.5-inch ID coil-over system, offering bolt-on compatibility with minimal fabrication required. QA1's lifetime guarantee ensures the spring will maintain 98% of its original free height, so you're investing in durability that matches your build's ambitions.
