Coilover Spring 7in x 2.5in 550LB Barrel

The SWIFT SPRINGS Coilover Spring 7in x 2.5in 550LB Barrel is a precision-engineered suspension component designed for builders and enthusiasts who demand responsive handling and precise ride height control. This coilover spring serves as the foundation for modern performance suspension systems, whether you're tuning a street car for daily comfort or setting up a track-focused platform.

Built by SWIFT SPRINGS—a manufacturer with proven expertise in suspension dynamics—this spring enables you to achieve repeatable, adjustable geometry that stock setups simply cannot match. With a 550-pound spring rate and a 7-inch free length paired with a 2.5-inch inner diameter, this barrel-style coilover spring delivers the stiffness required for controlled body roll while maintaining compliance during compression events. The barrel design concentrates load-carrying capacity in the active coil region, reducing buckling risk under lateral load and extending service life compared to linear spring profiles.

Mechanics and suspension technicians rely on SWIFT coilover springs for drift cars, road-racing platforms, and street applications where factory geometry is insufficient. The 550LB rate is aggressive enough for performance applications—ideal for vehicles running wider wheels, lowered stance geometries, or increased downforce—yet manageable for street driving when paired with appropriate dampers. This spring integrates seamlessly into coilover assemblies without adding significant unsprung mass.
