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.
