Coilover Spring 8in x 2.5in x 100lb

The Coilover Spring 8in x 2.5in x 100lb by SWIFT SPRINGS is an essential suspension component for serious automotive enthusiasts and fabricators building custom coilover systems. This precision-engineered spring is designed to work within a complete suspension assembly, providing the foundation for adjustable ride height and damping control. Whether you're building a track-focused setup, lowering a street car, or engineering a competition platform, a properly selected coilover spring determines how effectively your suspension responds to road inputs and maintains consistent geometry through corners.

This 8-inch coilover spring features a 2.5-inch inner diameter and 100-pound spring rate, specifications that define its load-bearing characteristics and deflection under compression. The 100lb/inch rate means the spring compresses approximately one inch for every 100 pounds of force applied—a moderate rate suitable for street and light motorsports applications on mid-weight vehicles. The 8-inch free length provides adequate travel range when paired with compatible dampers, allowing for proper suspension geometry tuning and adjustable ride height control. Quality coilover springs like this SWIFT offering are manufactured from high-tensile spring steel with precise winding geometry to ensure repeatability, consistent performance, and durability through thousands of compression cycles.

Mechanics and suspension builders select this coilover spring when assembling custom kits for vehicles requiring moderate spring rates and standard 2.5-inch bore compatibility. The 8-inch length and 100lb rate combination works well for compact and lightweight platforms, drift cars, autocross competitors, and street-performance builds where aggressive lowering isn't the primary goal. Installation requires proper damper selection—your shock absorber's piston rod diameter and overall length must match this spring's 2.5-inch inner diameter for seamless assembly. Always verify spring rate against your vehicle's corner weight and desired handling characteristics before purchase, and ensure all suspension components are torqued to manufacturer specification during installation.
