Coilover Spring 7in x 2.5in

The SWIFT SPRINGS Coilover Spring 7in x 2.5in (Model 070-250-350B) is a precision-engineered coil-over suspension component designed for enthusiasts and builders seeking fine-tuned ride control and adjustability in custom vehicle builds. This barrel-style spring serves as the core suspension element in coilover assemblies, enabling independent spring rate tuning and ride height adjustment that far exceeds OEM capabilities. Whether you're building a track-focused platform, lowering a street car, or dialing in suspension geometry for autocross competition, this coilover spring delivers the performance foundation serious modifiers demand.

Manufactured from high-quality steel and finished with a durable black powder coat, the coilover spring features a 7-inch length and 2.5-inch inner diameter (ID) configuration optimized for compact coilover mounting on modern and classic platforms. The 350 lb/in spring rate provides medium-stiff damping characteristics ideal for street-to-sport applications, offering responsive handling without excessive harshness on daily-driven vehicles. The barrel design—tapered coil geometry—ensures consistent load distribution, reduced spring surge, and predictable performance across suspension travel, while the powder-coated finish resists rust and corrosion in harsh weather and road salt environments. At 3.02 lbs per unit, the spring maintains minimal unsprung weight while delivering the structural integrity required for sustained track use or aggressive street driving.

This coilover spring is ideal for builders assembling custom coilover kits, upgrading factory suspension geometry, or creating adjustable lowering platforms on performance vehicles. Mechanics and suspension technicians favor SWIFT SPRINGS components for their repeatability and quality—each spring is individually wound and tested to specification tolerances. When pairing with appropriate shocks or dampers and adjustable perches, this 350 lb/in spring enables corner-weighting, ride height tuning, and suspension balance refinement that transforms vehicle dynamics. Installation requires basic suspension knowledge and proper tools; consult vehicle-specific coilover instructions and spring seating procedures to ensure safe, level installation and correct preload setup.
