Eibach ERS 16.00 in. Length x 3.00 in. ID Coil-Over Spring - 400 lb/in

The Eibach ERS 16.00 in. Length x 3.00 in. ID Coil-Over Spring with 400 lb/in rate serves as a high-performance component for custom coilover assemblies in drag racing, autocross, and street applications. This spring fits a broad range of coilover shocks and struts requiring precise 3-inch inner diameter and 16-inch free height. It delivers reliable handling, consistent ride quality, and endurance under demanding conditions.

Key Features

  • 16.00 in. Free Height: Provides ample suspension travel and customizable ride height in most coilover setups.
  • 3.00 in. Inner Diameter: Matches standard coilover body diameters (2.5-2.75 in. OD) for direct fitment.
  • 400 lb/in Linear Rate: Balances stiffness for sharp cornering, straight-line stability, and load handling.
  • Chrome Silicon Steel: High-tensile material shot-peened, preset, and scragged for sag resistance and fatigue life.
  • Zinc Plated Finish: Resists corrosion from road salt, moisture, and track environments.

Product Notes

  • Pair with compatible coilover shocks; verify body OD and perch design before purchase.
  • Store in dry conditions to maintain plating integrity.
  • Lightweight at 5.60 lbs for reduced unsprung mass.

Installation Notes

  • Professional installation recommended.
  • Use heavy-duty spring compressor rated for 400+ lb/in rates.
  • Compatible with aluminum or steel perches; torque to manufacturer specs.

Coilover Springs

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...
