Coilover Spring 7in x 2.5in 450LB Barrel

The Coilover Spring 7in x 2.5in 450LB Barrel by SWIFT SPRINGS is a precision suspension component engineered for vehicles requiring custom ride height and handling adjustments. Built for enthusiasts and mechanics who demand tunable suspension geometry, this barrel-style spring integrates seamlessly into coilover assemblies for street, track, and performance applications.

At 450 lbs/inch of spring rate, this coil spring resists compression with substantial force, making it ideal for heavier vehicles, turbocharged platforms, or setups running aggressive anti-roll bars and adjustable camber plates. The 7-inch free length and 2.5-inch outer diameter barrel design minimize binding and coil bind while maintaining compact packaging within typical coilover bodies. SWIFT SPRINGS manufactures these springs from high-tensile steel with precision winding tolerances, ensuring consistent rate and eliminating sag that compromises alignment stability over thousands of miles.

This spring is ideal for builders upgrading OEM coilovers or assembling custom coilover kits on front-wheel-drive, rear-wheel-drive, and all-wheel-drive vehicles. The barrel profile distributes load evenly across coils, reducing stress concentrations and extending service life in high-frequency bump and rebound cycles, making it a reliable choice for serious builds.
