Spring 6in Coil-Over 2.25in ID

The EIBACH Spring 6in Coil-Over 2.25in ID is a precision-engineered suspension component designed for high-performance coil-over systems and custom suspension builds. With a 450 lb/in spring rate, 6-inch length, and 2.25-inch inner diameter, this coil spring delivers the stiffness and geometry required for controlled load handling and consistent ride characteristics across varying driving conditions.

Built from high-grade steel with a red powder coat finish, this EIBACH coil-over spring resists corrosion and maintains structural integrity under repeated compression cycles. The 450 lb/in spring rate is moderate-to-firm, suitable for street-driven vehicles that require responsiveness without excessive harshness. The 2.25-inch ID accommodates standard shock absorber tubing, making this spring compatible with most coil-over kits and aftermarket suspension platforms. Weight of 1.95 lbs reflects the solid construction necessary for reliable performance in suspension duty.

This spring suits builders and enthusiasts upgrading to coil-over suspension for improved geometry, adjustability, and tuning capability. Whether for road course preparation, autocross duty, or street performance applications, the 6-inch coil-over spring provides the foundation for a properly balanced suspension setup. EIBACH's reputation for precision spring manufacturing makes this component a trusted choice for suspension specialists and serious automotive builders.

Coil-over springs are engineered to work within complete suspension systems where spring rate, mounting height, and shock damping must be matched for optimal performance. The 450 lb/in rate positions this spring in the moderate stiffness range, offering a practical balance between wheel control and ride comfort for daily-driven or weekend-use performance vehicles.
