Conv. Spring Front 5.5in ID 9.5in Tall 400lb

The DRACO RACING Conv. Spring Front 5.5in ID 9.5in Tall 400lb is a purpose-built front coil spring engineered for high-performance suspension tuning and custom vehicle modifications. Designed for enthusiasts and shop mechanics who demand precision control over ride height, spring rate, and handling characteristics, this conventional coil spring delivers the stiffness and consistency required for competitive driving, autocross, or aggressive street setups. Whether you're building a track-focused chassis or dialing in a custom lowered stance, this spring provides the foundation for repeatable, controlled suspension geometry.

Manufactured from high-grade steel with a durable purple powder-coat finish, the DRACO RACING spring features a 5.5-inch inside diameter and 9.5-inch free length, paired with a 400 lb/in spring rate that strikes a balance between responsive handling and real-world comfort on varied road surfaces. The 400 lb/in rate is stiffer than OEM springs, reducing body roll and dive under braking while maintaining enough compliance to absorb road imperfections—critical for maintaining tire contact and traction. The purple coating provides corrosion resistance and visual identification, essential for organized suspension work where multiple spring rates are in play. Weighing 5.84 lbs per unit, these springs are optimized for front-end applications where unsprung weight directly impacts steering response and ride quality.

Front suspension applications benefit most from this spring's stiffer rate, particularly in vehicles running aftermarket lowering kits, coilover systems, or custom independent front suspensions. Mechanics and builders commonly pair 400 lb/in front springs with matched rear rates to achieve balanced weight transfer and predictable handling during cornering and acceleration. Installation requires proper tools—spring compressors are essential for safe removal and installation—and verification that the spring's 5.5-inch ID diameter matches your vehicle's strut or spring perch design. Verify compatibility with your specific make, model, and year before ordering, as suspension geometry and mounting interfaces vary widely across platforms.
