Spring 5in Coil-Over 2.25in ID

The Spring 5in Coil-Over 2.25in ID from EIBACH is a precision-engineered coil spring designed for high-performance suspension systems where load isolation and durability are critical. Built to handle demanding automotive and industrial applications, this coil-over spring delivers consistent support and responsive handling characteristics. Whether you're upgrading a custom suspension setup, restoring a performance vehicle, or engineering a specialized application, this spring provides the structural reliability and tuning precision that professionals demand.

This spring features a 5-inch compressed length with a 2.25-inch inner diameter and a robust 600 lb/in spring rate, making it suitable for applications requiring substantial load support and minimal deflection under stress. The steel construction is finished with a durable red powder coat that resists corrosion and provides long-term protection in challenging environments. The 600 lb/in rate ensures precise wheel control and consistent ride height across varying load conditions, while the compact 5-inch profile integrates seamlessly into space-constrained suspension designs. Each spring is manufactured to EIBACH's exacting standards for consistent performance and longevity.

This coil-over spring is ideal for fabricators, suspension specialists, and enthusiasts building custom lowered systems, air suspension platforms, or performance upgrades. The 2.25-inch ID accommodates standard coil-over shock bodies and dampers, making compatibility straightforward across most aftermarket and custom builds. Installation requires proper suspension knowledge and appropriate tools to safely compress and seat the spring. At 1.73 lbs, the spring's weight contributes minimal unsprung mass while maintaining structural integrity under load. Proper spring rate selection is essential—verify that the 600 lb/in specification matches your vehicle's weight distribution and suspension geometry for optimal performance and safety.
