Eibach Elastomeric Bump Stop | 0.91in ID | 2.72in Length | 976 lb/in Rate

Progressive Bottoming Control for Precision Suspension Tuning

The final inches of suspension travel are where performance meets control — and where the Eibach Elastomeric Bump Stop proves its worth. Designed to deliver progressive bottoming control, this bump stop ensures your suspension transitions smoothly into full compression, protecting components while maintaining vehicle composure under load.

Manufactured from Eibach’s race-proven micro-cellular polyurethane elastomer, this component acts as a secondary spring, engaging progressively to absorb impact energy without harshness. The result is predictable, repeatable suspension performance whether you’re tuning a track-ready road car, off-road pre-runner, or custom coilover setup.

Engineered with a 0.91-inch inner diameter, 2.72-inch overall length, and a 976 lb/in rate, the Eibach EBS770051 provides firm yet controlled engagement across a wide range of suspension systems.

Engineered for Real-World Demands

This isn’t just a bump stop — it’s a precision energy management device. Eibach’s micro-cellular elastomer material combines lightweight flexibility with the structural consistency needed to handle repeated compression cycles. Each bump stop undergoes laboratory and motorsport testing to ensure consistent durometer, rate accuracy, and recovery speed.

With near-zero lateral expansion, this design minimizes deflection off-axis, maintaining true vertical compression and protecting shock shafts and seals from uneven loads. Whether you’re running through desert whoops or late-braking into a hairpin, Eibach’s elastomeric bump stops absorb impact forces efficiently while maintaining control through rebound.

The Role of Progressive Bottoming Control

Bottoming out isn’t just about impact — it’s about managing how energy is dissipated when your suspension reaches its limit. The Eibach Elastomeric Bump Stop works like a progressive damper, ramping up resistance gradually rather than hitting a hard stop.

This smooth transition prevents shock piston damage, reduces harsh feedback through the chassis, and stabilizes the vehicle during high-speed or heavy-load conditions. In motorsport and off-road tuning, this means better wheel control, faster recovery, and longer shock life — all without compromising total travel or ride comfort.

When properly matched to your main spring and shock setup, this bump stop effectively becomes part of your suspension tuning toolkit — allowing you to fine-tune end-stroke resistance and improve handling predictability at the limit.

Installation and Setup

Installation is straightforward and application-specific. The 0.91-inch inner diameter fits most shock shafts and bump can applications with matching mounts. Simply verify shaft diameter and available compression clearance before installation.

For coilover setups, pair with an appropriate bump stop seat or canister retainer to ensure proper alignment and contact during compression. When installed correctly, the Eibach bump stop will engage progressively without coil bind or premature bottoming.

⚙️ Setup Tip:
Fine-tune engagement timing by adjusting shock stroke or mounting depth. For softer end-stroke response, engage the bump stop earlier. For maximum travel with sharper engagement, set it later in the compression cycle.

Tested, Trusted, and Proven

Every Eibach elastomeric bump stop is manufactured under ISO 9001 and TÜV-certified standards, ensuring consistent performance across thousands of compression cycles. The result is a tuning component that offers precise load control and reliability worthy of professional-level use.

From road course suspension tuning to full desert race applications, Eibach’s bump stops are proven to withstand heat, fatigue, and constant motion while maintaining predictable engagement characteristics.

This same attention to detail and performance engineering is what makes Eibach a world leader in suspension development — and why Fenix Motorsports proudly carries their components.
