Product Details

The Eibach 1200.250.0250 is a high-performance race main spring designed for the legendary ERS (Eibach Race Spring) double-spring system. This precision-engineered coilover spring features a 2.5-inch inner diameter, 12-inch free length, and a 250 lb/in spring rate, delivering the optimal balance between compliance and control that serious racers demand.

ERS Double-Spring System Technology:

Eibach's ERS system uses a Main and Tender spring concept that provides exceptional tuning flexibility. The Main spring delivers a linear-rate characteristic that determines the final rate of the system, while Tender springs control the initial rate. This configuration allows for a softer initial compression when both springs work together, then transitions to a firmer ending rate once the tender spring fully compresses—giving you superior control over weight transfer, body roll, and suspension response.

Key Features:

  • Linear-rate main spring with 250 lb/in spring rate for predictable suspension behavior
  • 2.5-inch inner diameter and 12-inch length optimized for race applications
  • Compatible with over 700 ERS components for nearly unlimited suspension tuning combinations
  • Shot-peened surface treatment for enhanced fatigue resistance and longevity
  • High spring travel and deflection capability with short mounting lengths
  • Precision tolerances ensure consistent performance and proper fitment
  • Advanced corrosion protection through phosphating and durable epoxy coating
  • Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
  • High block resistance for extreme compression scenarios

Engineered for professional race teams and serious enthusiasts, this ERS main spring provides the foundation for a precisely tuned suspension system that maximizes tire contact, minimizes body motion, and delivers consistent performance lap after lap. Each spring is individually packaged and manufactured to Eibach's exacting quality standards.
