The Eibach ERS 8.00 inch L x 2.50 inch dia x 450 lbs Coil Over Spring delivers precise spring force for custom coilover builds. Designed for 2.5-inch inner diameter shocks, it suits high-performance racing and street applications requiring firm suspension response. This spring ensures consistent rates under extreme loads for better cornering and stability.
Key Features
- Exact Dimensions: 8.00-inch free length x 2.50-inch diameter supports compact strut assemblies with 450 lb/in linear spring rate for predictable damping.
- Premium Material: Wound from high-tensile chrome silicon ASTM A227 Class II steel resists fatigue in demanding track conditions.
- Shot Peened Construction: Quadruple shot peening plus 550°F stress relieving extends spring life by up to 400% over standard springs.
- Corrosion Protection: Black powder coat finish guards against rust and maintains performance in wet environments.
- Precision Engineering: Manufactured with Eibach's Pro-Street-Line tolerances (±1% rate accuracy) for repeatable setup in coilover systems.
Product Notes

Coilover Springs
Coilover springs are the replaceable compression springs that wrap around the shock body in a coilover assembly, determining ride height, spring rate, and the balance between comfort and handling stiffness. Swapping springs is the most direct way to tune a coilover setup for a new application without buying an entirely new system.Popular UpgradesLinear-rate springs in the 6 to 12 kg/mm range are the most popular choice for street performance and track day builds where predictable handling is more important than maximum compliance. Progressive-rate springs that soften on small bumps and stiffen under load are preferred for street cars that need to be both comfortable on rough roads and controlled in hard cornering. ID60 and ID65 springs are the most common inner diameter specifications across popular coilover platforms.What is the difference between linear and progressive coilover springs?A linear spring has a constant rate from full droop to full compression, providing consistent an...
