Eibach ERS 6.00 inch L x 2.25 inch dia x 300 lbs Coil Over Spring
This Eibach ERS coilover spring offers a 6.00-inch free height, 2.25-inch inside diameter, and 300 lbs per inch spring rate for coilover suspension systems. Designed for universal fitment in racing and performance coilover shocks, it supports custom setups on drag cars, autocross vehicles, and street performance builds. Expect improved cornering response and chassis control from its consistent rate and lightweight construction.
Key Features
- Chrome Silicon Steel: High-tensile alloy resists fatigue for reliable performance over thousands of cycles in demanding conditions.
- Shot Peened Finish: Surface treatment boosts strength and extends service life under high-load racing use.
- Preset and Scragged: Eliminates initial sag to maintain ride height and handling from the first lap.
- Ground Flat Ends: Squared ends ensure full contact with perches for even load distribution and stability.
- 300 lb/in Rate: Provides firm damping control suited for rear coilovers on lighter vehicles or front setups on heavier chassis.
Product Notes
- Confirm coilover shock inner diameter matches 2.25 inches before purchase.
- Store in a cool, dry location to preserve coating integrity.
- Ships via standard ground service with tracking provided.
Installation Notes
- Professional installation recommended.
- Use thread locker on adjuster collars and torque to manufacturer specs.

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...
