Coil Spring - 2.5in x 9 220#

The Coil Spring – 2.5in x 9 220# is a high-travel coil-over suspension component engineered for serious vehicle modifications, custom builds, and performance applications. Whether you're upgrading a lifted truck, tuning a track-focused platform, or building a custom chassis, this spring delivers the precise load-carrying capacity and travel characteristics needed for controlled suspension geometry. Designed for builders and enthusiasts who demand reliability and repeatability, this coil spring is the foundation of responsive, well-tuned suspension systems.

This coil spring features a 2.5-inch inner diameter (ID), a 9-inch free length, and a 220 pound-per-inch spring rate, making it ideal for mid-range vehicle weights and moderate to aggressive suspension travel demands. The 220 lb/in rate provides sufficient stiffness to support lifted applications and performance setups without excessive harshness on street driving. Constructed from steel and finished with a silver powder coat for corrosion resistance and durability, the spring resists road salt, moisture, and UV degradation. The powder-coat finish also minimizes surface contamination that can compromise long-term performance in harsh environments or extended storage.

This spring is best suited for coil-over suspension systems, making it compatible with adjustable damper setups commonly found in lifted trucks, off-road rigs, and street-performance vehicles. The 2.5-inch ID and 9-inch length pair well with standard coil-over bodies, allowing for easy tuning of ride height and suspension preload. Always verify your specific platform's spring seat dimensions and total suspension travel before installation to ensure optimal performance. Proper setup with matched dampers and geometry correction will yield a balanced, responsive suspension capable of handling both street comfort and demanding terrain.
