Coilover Spring 10in x 2.5in x 100lb

The Coilover Spring 10in x 2.5in x 100lb by SWIFT SPRINGS represents a precision-engineered suspension component designed for automotive enthusiasts and professional mechanics seeking to fine-tune vehicle handling dynamics. This 10-inch coilover spring is engineered for applications where weight transfer control and ride height adjustment are critical to performance tuning. Whether you're building a track-focused setup, lowering a street car, or developing a custom suspension geometry, this spring delivers the progressive spring rate needed to maintain consistent damping response across varied load conditions.

The 100-pound spring rate provides a middle-ground stiffness ideal for drivers balancing comfort and cornering performance without sacrificing daily driveability. At 2.5 inches in diameter and weighing just 2.38 pounds, this spring integrates seamlessly into most aftermarket coilover assemblies while maintaining lightweight construction—a critical factor in unsprung weight reduction that directly improves braking response and acceleration. The 10-inch free length accommodates both lowered ride heights and progressive-rate suspension geometry, allowing mechanics to dial in precise suspension kinematics without compromising shock absorption or bottoming-out risk during aggressive driving or track days.

This coilover spring is ideal for sport compact vehicles, drift platforms, and street performance builds where adjustable ride height and tunable spring rates are essential for optimal performance. Mechanics and builders commonly pair 100lb springs with coilover dampers on vehicles in the 2,500–3,500 lbs range to achieve predictable corner entry behavior and mid-corner stability. When sourcing replacement springs or assembling a complete coilover kit, confirm shock body bore diameter compatibility and verify that your damper assembly accepts 2.5-inch diameter springs to ensure proper fitment and sustained performance across your suspension envelope.
