Eibach ERS 7.00 inch L x 2.50 inch dia x 350 lbs Coil Over Spring - Universal Racing Fit
Eibach ERS coilover spring delivers 7.00 inch free length, 2.50 inch diameter, and 350 lbs per inch rate for custom coilover setups on drag cars, road race vehicles, and street performance builds. Engineered for extreme conditions, it maintains consistent rates under high loads for sharp cornering and launch stability. MPN 0700.250.0350 pairs with most 2.5 inch shock bodies from QA1, Bilstein, and Fox.
Key Features
- Chrome Silicon Steel: High-tensile alloy resists fatigue, supports repeated high-stress cycles in racing.
- Shot-Peened Process: Increases surface strength, reduces sag for reliable performance over thousands of passes.
- 350 lbs Rate: Provides firm response for drag launches or autocross grip, with progressive design for compliance.
- Precise Dimensions: 7.00in tall x 2.50in diameter ensures drop-in fit on standard coilover perches and retainers.
- Powder Coat Finish: Dual-layer green coating prevents rust, withstands track chemicals and weather exposure.
Product Notes
- Measure shock body and perch for 2.50in inner diameter compatibility prior to install.
- Spring rate tested at 40% compression; actual installed rate varies with preload.
- Packed in protective cardboard sleeve; store vertically to preserve coil shape.
Installation Notes
- Professional installation recommended.
- Apply anti-seize to perches; preload to 20-30% of free height before assembly.
- Compatible with aluminum or steel coilover hardware; use nylon or Delrin spacers.

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...
