Eibach 1100.550.1300 Conventional Front Spring for Stock Car Racing

The Eibach 1100.550.1300 is a precision-engineered conventional front spring designed for stock car racing applications. This high-performance spring is part of Eibach's renowned ERS (Eibach Race Spring) system, which transforms engine power into optimal track adhesion through carefully balanced suspension tuning.

ERS Double Spring System Technology:

This spring integrates into Eibach's world-famous ERS double-spring system, offering nearly unlimited suspension combinations from over 700 different single spring components. The system utilizes a Main and Tender spring concept that delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This innovative design reduces body roll, squat, and dive during cornering, acceleration, and braking while maintaining road contact over irregularities.

Key Features:

• Linear-rate conventional spring design for predictable suspension behavior
• High spring travel (deflection) delivering exceptional end loads at short mounting lengths
• Shot-peened surface treatment for enhanced durability and fatigue resistance
• Superior corrosion protection through phosphating and epoxy coating
• Precision manufacturing with tight tolerances for consistent performance
• Block resistance design prevents coil binding
• Clearly imprinted with part number indicating spring rate and physical dimensions
• High dynamic durability ensures extended component longevity under racing conditions
• Compatible with Eibach connecting plates for main/tender spring configurations
• Individual protective packaging prevents damage during storage and transport

Compatible with Helper springs to prevent spring looseness at full droop (up to 50mm spring-to-perch gap) and various Tender springs for customized initial rate characteristics. Each spring is manufactured to exacting standards, making it suitable for professional racing teams and serious weekend racers alike.
