Eibach 1100.550.0900 ERS Conventional Front Racing Spring

The Eibach 1100.550.0900 is a conventional front spring designed for racing applications, delivering precision-engineered performance for stock car and motorsport suspension systems. A properly tuned spring system transforms engine power to the track through optimal adhesion, balancing compliance for road irregularities with the firmness needed to control body roll, squat, and dive during high-performance driving.

ERS Double Spring System Compatibility:

This spring is part of Eibach's renowned ERS (Eibach Race Spring) system, which combines over 700 different spring components to create nearly unlimited suspension combinations. The ERS system utilizes a Main and Tender spring concept that provides a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. The Main spring features linear-rate characteristics and determines the final system rate, while Helper springs prevent the Main spring from loosening at full droop without affecting suspension characteristics.

Key Features:

• Conventional linear-rate front spring for racing applications
• High spring travel (deflection) with high end loads at short mounting lengths
• Shot-peened surface treatment for enhanced durability
• Exceptional dynamic durability ensures long component life
• Precise manufacturing tolerances for consistent performance
• Block resistance for reliable operation at compression limits
• Premium corrosion protection through phosphating and epoxy coating
• Part number imprinted on spring indicating spring rate and physical dimensions
• Individual protective packaging for safe shipping and storage
• Compatible with Eibach Connecting Plates for Main/Tender spring configurations

Engineered for professional racing teams and serious motorsport enthusiasts, this Eibach conventional front spring delivers the precision and reliability demanded by competitive racing environments.
