Coilover Spring 10in x 2.5in x 275lb

The Coilover Spring 10in x 2.5in x 275lb from SWIFT SPRINGS is a precision suspension component engineered for drivers and mechanics who demand refined ride quality and handling responsiveness. This coilover spring sits at the heart of modern suspension tuning, replacing worn or inadequate factory springs to restore vehicle geometry, reduce body roll, and improve overall chassis dynamics. Whether you're building a track-focused platform, lowering a street machine, or refreshing tired suspension on a daily driver, this spring delivers the foundation for predictable, controlled performance across varying driving conditions.

With a 10-inch free length and 2.5-inch inner diameter, this SWIFT SPRINGS coilover is designed to work with coilover shock assemblies, allowing you to fine-tune ride height and spring preload independently. The 275-pound spring rate strikes a balance between responsive handling and livable compliance—stiff enough to minimize suspension travel and reduce dive-and-squat during acceleration and braking, yet compliant enough for street use without excessive harshness. The compact 4.4 x 4.4-inch profile and 3.88-pound weight ensure straightforward installation in most aftermarket and OEM coilover platforms while maintaining structural integrity under load cycling and thermal stress.

This spring benefits suspension builders, performance mechanics, and enthusiasts working with bolt-on coilover kits from established manufacturers. Verify spring seat diameter, length, and rate compatibility with your specific coilover unit before purchase, as fitment varies across platforms and brands. Installation pairs best with quality shock absorbers matched to the 275lb rate, fresh suspension bushings, and proper wheel alignment to unlock the full potential of your suspension upgrade and maximize tire contact patch quality.
