Eibach ERS 8.00 inch L x 2.25 inch dia x 500 lbs Coil Over Spring - Universal Coilover Fit
This Eibach ERS coil over spring measures 8.00 inches in free length with a 2.25 inch diameter and 500 lbs per inch rate, designed for high-performance coilover shocks. It fits most coilover struts and shocks featuring 2.25 inch body diameters used in drag racing, road racing, and street performance setups on cars, trucks, and imports. Engineered for consistent response and resistance to sagging, it supports precise suspension tuning for better cornering and stability.
Key Features
- Spring Rate: 500 lbs per inch delivers firm control for aggressive driving and track use without compromising ride quality on street setups.
- Dimensions: 8.00 inch free height and 2.25 inch outer diameter ensure compatibility with standard coilover shock bodies from QA1, AFCO, and similar systems.
- Material: High-tensile chrome-silicon steel provides exceptional strength and fatigue resistance under repeated high-load cycles.
- Processing: Shot-peened, stress-relieved, and preset during manufacturing to maintain rate stability and prevent settling over time.
- Finish: Black epoxy powder coating protects against corrosion and harsh track environments for long-lasting performance.
Product Notes

- Store in a dry area to preserve coating integrity and spring performance.
- Ships as a single spring unit via standard ground service.
