Conv Front Spring 5.5in x 9.5in x 700

The Conv Front Spring 5.5in x 9.5in x 700 from INTEGRA SHOCKS is a professional-grade coil spring engineered for drivers who demand precise suspension tuning and consistent handling performance. Whether you're building a track-focused daily driver, restoring a classic muscle car, or fine-tuning an independent rear suspension (IRS) system, this conventional front spring delivers the predictable spring rate needed for controlled ride quality and accurate suspension geometry. This is the spring choice for mechanics and enthusiasts who understand that suspension compliance directly impacts cornering grip, brake dive control, and overall vehicle stability.

Built from high-strength steel and finished with a durable black powder coat, the Conv Front Spring features a 700 lb/in spring rate with 5.5-inch outer diameter and 9.5-inch free length—specifications that provide a moderate spring constant suitable for street and mild performance applications. The conventional coil design offers linear load response with minimal hysteresis, meaning predictable damping characteristics that work seamlessly with aftermarket shocks and struts. At 10.95 lbs, this spring is engineered for weight efficiency without sacrificing structural integrity, and the compact 5.9 x 5.7 x 10.1-inch package dimensions make it straightforward to fit into tight suspension bays during installation or replacement.

This front spring is ideal for independent rear suspension conversions, vintage hot rods, and modern performance vehicles where OEM springs fall short of handling demands. The 700 lb/in rate strikes a balance between comfort and control—stiff enough to minimize body roll during aggressive driving but compliant enough to absorb road imperfections without excessive harshness. Installation pairs best with quality dampers matched to the same spring rate; verify your vehicle's suspension design and mounting points before ordering to ensure proper fitment and ride height optimization.
