Eibach 1100.550.1100 Stock Car Conventional Front Spring

The Eibach 1100.550.1100 is a conventional front spring engineered for stock car racing applications. This high-performance spring is part of Eibach's renowned ERS (Eibach Race Spring) system, designed to transform engine power into optimal track adhesion through precisely tuned suspension dynamics.

ERS Double Spring System:

This spring is compatible with Eibach's innovative ERS double-spring system, which combines Main and Tender springs to deliver sophisticated rate characteristics. 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. With over 700 different single spring components available, the ERS system offers nearly unlimited tuning combinations for suspension engineers and racing enthusiasts.

Key Features:

• Shot-peened surface treatment for enhanced fatigue resistance
• High spring travel and deflection capacity at compact mounting lengths
• Superior block resistance for consistent performance
• Exceptional dynamic durability for extended component life
• Manufactured to precise tolerances for predictable behavior
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
• Compatible with Eibach Helper springs to prevent spring looseness at full droop
• Works with Eibach Connecting Plates for Main/Tender spring combinations

Engineered to balance road contact and body control, this spring helps reduce body roll, squat, and dive during cornering, acceleration, and braking while maintaining the compliance needed for track irregularities. Each spring is individually packaged for protection during storage and transport.
