18IN COIL OVER SPRING 3 IN ID SILVER

The 18IN COIL OVER SPRING 3 IN ID SILVER from Eibach is a precision-engineered coil-over suspension component designed for high-performance automotive applications where custom ride height and spring rate tuning are essential. This individual spring serves as a critical suspension element for builders and enthusiasts who demand adjustable damping characteristics and reliable load support. Whether upgrading a street performance vehicle or building a dedicated race platform, this coil-over spring delivers the consistency and durability required for controlled handling and stability across varied driving conditions.

Built from high-quality steel and finished with a durable silver powder coat, the 18IN COIL OVER SPRING 3 IN ID SILVER features a 500 lb/in spring rate that provides moderate stiffness suitable for both street and motorsport applications. The 3-inch inner diameter (ID) accommodates standard damper bodies, while the 18-inch length accommodates most coil-over suspension designs. The 500 lb/in rate strikes a balance between supporting vehicle weight and maintaining ride comfort, making it versatile for various setups and load requirements. The silver powder-coated finish resists corrosion and presents a clean aesthetic while protecting against environmental degradation.

This spring is ideal for suspension tuners, performance shops, and dedicated enthusiasts building or refreshing coil-over systems on street cars, track vehicles, and autocross platforms. Proper installation requires secure seating on compatible damper bodies with correct preload adjustment to achieve desired ride height and handling balance. Verification of vehicle weight distribution and target spring frequencies ensures optimal performance; consult suspension geometry data and damper specifications before final assembly. Each spring is sold individually, so multiple units may be required depending on your platform's suspension design.
