Eibach ERS Bump Stop EBS770040

Eibach Bump Stops are a vital part of a well-engineered suspension system, and are used to create a highly progressive, rising-rate effect as springs approach bottoming and possible coil binding. We offer an extensive range in various designs, sizes and spring-rate characteristics, to suit just about any form of racing. Individual Bump Stop

• Extensive Range of Rates and Dimensions for Maximum Tuning Flexibility
• Tremendous Deflection Potential with Near-Zero Lateral Expansion
• Made from Race-Proven Micro-Cellular Polyurethane Elsatomer
• Progressive Compression Characteristics
• Secondary Spring Tuning

The Eibach ERS Bump Stop is an individual suspension component designed to provide controlled, progressive support as a spring approaches full compression. By creating a rising-rate effect near bottoming, this bump stop helps manage suspension travel, reduce the risk of coil bind, and provide additional tuning control for performance and racing applications.

Manufactured from race-proven micro-cellular polyurethane elastomer, the Eibach bump stop delivers substantial deflection with minimal lateral expansion. Its progressive compression characteristics allow the suspension to transition smoothly into secondary spring support rather than reaching an abrupt mechanical stop. This design gives chassis tuners greater control over suspension behavior and helps maintain predictable performance under demanding conditions.

The Eibach ERS Bump Stop EBS770040 is part of an extensive range of bump stops offered in multiple rate characteristics and designs. This flexibility allows the component to be selected and integrated according to the vehicle’s suspension geometry, spring rate, available travel, and intended use. It is suitable for custom suspension development, motorsports, and other applications requiring precise secondary spring tuning. This product is supplied individually, so verify application requirements and suspension compatibility before installation.
