Eibach ERS Linear Main Spring - Silver 3.00" I.D. x 2.00" Universal Coilover

Eibach ERS Linear Main Spring delivers race-proven performance in coilover suspension setups. This silver coilover spring features a 3.00-inch inside diameter and 2.00-inch free length with a consistent 4.0 lb/in linear rate for responsive handling in drag, road race, and autocross applications. Built from high-tensile chrome silicon steel, it withstands extreme conditions while maintaining precise ride control.

Key Features

  • Linear Spring Rate: 4.0 lb/in (0.70 kg/mm) provides predictable damping and suspension response under load.
  • 3.00" Inside Diameter: Direct fit for standard 2.5-inch shock body coilovers used in performance builds.
  • 2.00" Free Length: Compact design lowers center of gravity for improved stability and cornering grip.
  • Silver Shot-Peened Finish: Increases surface durability, resists corrosion, and extends fatigue life in harsh environments.
  • Chrome Silicon Construction: Heat-treated and preset for zero sag and reliable performance over thousands of cycles.

Product Notes

  • Confirm perch ID and shock diameter match 3.00" before installation.
  • Pair with matching Eibach bump stops for full stroke utilization.
  • Standard ground shipping; handles like standard package freight.

Installation Notes

  • Professional installation recommended.
  • Compress spring safely using coil spring compressor tool.
  • Compatible with most threaded body coilovers like QA1, Penske, and Bilstein; verify thread pitch.
