Eibach ERS 5.00 inch L x 2.25 inch dia x 800 lbs Coil Over Spring (Universal Fit)

Eibach ERS coilover springs deliver a precise 800 lbs/in rate in a 5.00-inch free length and 2.25-inch inside diameter for custom coilover assemblies. Designed for drag racing, road course, off-road, and high-performance street applications, this single spring maintains consistent rates under heavy loads. It reduces body roll and improves cornering response with reliable deflection control.

Key Features

  • Spring Rate: 800 lbs per inch provides firm response for high-grip track conditions and heavy vehicle setups.
  • Dimensions: 5.00 inches free length x 2.25 inches inside diameter fits standard coilover shocks in compact spaces.
  • Construction: Chrome silicon steel shot-peened and preset resists fatigue for extended spring life.
  • End Design: Ground square and flat ensures secure, even seating on perches without slippage.
  • Rate Coding: Factory-applied color stripe allows instant identification during setup and maintenance.

Product Notes

  • Sold individually as a single coilover spring for precise matching in dual-spring or custom configurations.
  • Regular inspection advised to check for cracks or rate loss in racing environments.
  • Packaged in protective tube to prevent shipping damage and maintain spring shape.

Installation Notes

  • Professional installation recommended.
  • Verify coilover shock perch diameter matches 2.25-inch spring ID before assembly.
  • Adjust preload to achieve desired ride height; torque hardware to manufacturer specs.
