Conv. Spring Front 5.5in ID 9.5in Tall 550lb

The DRACO RACING Conventional Spring Front 5.5in ID 9.5in Tall 550lb is a precision coil spring engineered for high-performance suspension tuning in racing and motorsport applications. This front-mounted conventional spring delivers a 550 lb/in spring rate, making it suitable for vehicles requiring responsive, linear spring behavior across a wide range of load conditions and track scenarios.

The 5.5-inch inner diameter and 9.5-inch overall height establish a compact footprint designed for space-constrained engine bays while maintaining adequate travel and load capacity. The 550 lb/in rate provides moderate progressive stiffness—stiffer than street springs but manageable for street-and-strip duty or weekend track use. Steel construction with durable purple powder coat finish resists corrosion and thermal degradation, ensuring consistent performance across multiple sessions. The linear rate characteristic means spring force increases predictably with suspension compression, enabling drivers to tune chassis balance with precision.

This spring is ideal for engine builders, suspension shops, and enthusiasts upgrading stock or worn suspension components on street, road-course, and bracket-racing vehicles. Proper spring selection depends on matching the rate to vehicle weight, intended ride height, and suspension geometry—making it essential to verify compatibility with your specific application before purchase.

Sold individually. Pair with a matching rear spring and quality dampers for complete suspension performance. Each spring must be inspected for cracks or permanent deformation before installation, and coil springs should be compressed evenly during installation to prevent binding or misalignment.
