Coilover Spring 3.0in ID 8in Tall 450lb

The Coilover Spring 3.0in ID 8in Tall 450lb from DRACO RACING is purpose-built for serious suspension tuning on street and track vehicles. Coil-over springs form the backbone of adjustable suspension systems, allowing drivers to dial in ride height, spring rate, and damping characteristics with precision. Whether you're lowering a performance car, upgrading to independent suspension geometry, or building a competition rig, this 450 lb/in spring rate delivers the stiffness needed for controlled body roll and consistent handling across varied loads and track conditions.

Manufactured from high-tensile steel and finished in durable purple powder coat, this coil-over spring measures 8 inches in length with a 3.0-inch inner diameter, engineered to integrate with most aftermarket coilover dampers and sleeves on the market. The 450 lb/in spring rate—measured as the resistance force per inch of compression—strikes a balance between street compliance and track responsiveness, making it suitable for road course use, autocross, and aggressive street applications where factory suspensions fall short. The compact 4.5 x 4.35 x 11.55-inch package and 3.67-pound weight ensure minimal unsprung mass while maintaining the structural rigidity required for sustained cornering and braking loads.

Buyers upgrading suspension systems on sports cars, drift platforms, or time-trial vehicles will find this spring ideal when paired with quality dampers and adjustable mounts. Installation requires proper suspension geometry knowledge and correct pairing with a compatible coilover body; verify inner diameter and spring seat design before ordering. The 450 lb/in rate works best on lighter vehicles or in front-axle applications where moderate spring rates prevent excessive harshness while maintaining sharp turn-in response and body control during aggressive driving maneuvers.
