Eibach 1600.250.0400S Silver Coilover Spring ID Off-Road Racing - 2.5

The Eibach 1600.250.0400S is a high-performance off-road coilover spring featuring a 2.50" inner diameter, designed for racing and performance suspension applications. This silver-finished spring is part of Eibach's renowned ERS (Eibach Race Spring) system, engineered to transform engine power into optimal track adhesion through precisely balanced suspension tuning.

ERS Double Spring System Benefits:

This spring is compatible with Eibach's innovative double-spring configuration, which combines Main and Tender springs to deliver progressive suspension response. The system provides a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This design reduces body roll, squat, and dive during cornering, acceleration, and braking while maintaining compliance over road irregularities.

Key Features:

• Shot-peened surface treatment for enhanced fatigue resistance
• High spring travel and deflection capacity with short mounting lengths
• Premium corrosion protection through phosphating and epoxy coating
• Precise manufacturing tolerances for consistent performance
• Block resistance design for maximum durability
• Part number imprinted on spring indicating rate and physical dimensions
• Compatible with Eibach connecting plates for tender spring configurations
• Individual protective packaging

This spring is ideal for suspension engineers and racing enthusiasts building custom coilover systems. When combined with other ERS components from Eibach's extensive catalog of over 700 spring options, this system offers virtually unlimited tuning possibilities for optimized vehicle dynamics.
