Conv. Spring Front 5.5in ID 10.5in Tall 375lb

The DRACO RACING Conventional Spring Front 5.5in ID 10.5in Tall 375lb is a precision coil spring engineered for front-end suspension tuning in competitive motorsports and high-performance vehicles. This conventional coil spring delivers a 375 lb/in spring rate with a 5.5-inch inner diameter and 10.5-inch compressed height, providing the progressive load support necessary for consistent handling during cornering, acceleration, and braking events.

The 375 lb/in spring rate is the critical specification here. For front suspension applications, this rate influences both ride quality and chassis geometry. A stiffer spring resists body roll during aggressive maneuvers and maintains suspension ride height under dynamic loads, but at the cost of increased harshness on uneven surfaces. The 10.5-inch length and 5.5-inch ID have been sized to fit within standard front suspension packaging on purpose-built race cars and track-focused street vehicles. Purple powder coat finish protects the steel against corrosion while allowing easy visual identification in the engine bay or suspension workspace.

This coil spring is intended for buyers actively tuning front suspension geometry—road racing drivers, autocross competitors, and fabricators working on independent front suspension systems. Spring rate selection depends on vehicle weight, desired roll stiffness, and front-to-rear balance; the 375 lb/in rate suits mid-weight platforms requiring moderate spring support without extreme preload. Each spring is sold individually, allowing buyers to match pairs or stack springs to achieve target spring rates.

DRACO RACING coil springs are designed within the motorsports aftermarket, where suspension geometry and ride frequency directly affect lap times and vehicle control. When selecting a front spring, verify mounting point spacing, available suspension travel, and load capacity against your vehicle's curb weight and expected dynamic loads to ensure safe and effective operation.
