Eibach Elastometric Bump Stop 0.35ID 2.76in Tall

Eibach Elastomeric Bump Stop | 0.35in ID | 2.76in Length | 1011 lb/in Rate Precision-Tuned Bottoming Control for Maximum Suspension Performance Every suspension system has a limit — but how it behaves at that limit defines the difference between control and chaos. The Eibach Elastomeric Bump Stop provides progressive bottoming control, absorbing energy smoothly and predictably to prevent harsh impact when your suspension reaches full compression. Designed using Eibach’s race-proven micro-cellular polyurethane elastomer, this bump stop transitions gradually from soft engagement to firm support, maintaining chassis balance and driver confidence under extreme load. Whether you’re running coilovers on a circuit car, bypass shocks on an off-road rig, or dialing in your own suspension package, this bump stop helps you tune bottom-out characteristics with the same precision Eibach applies to its world-class spring systems. Engineered to Perform Under Pressure Built for motorsport and performance applications, Eibach’s EBS770060 bump stop is engineered to act as a secondary spring, adding dynamic resistance only when needed. Its progressive engagement curve reduces shock stress and protects your suspension components from hard impacts — while still preserving maximum wheel travel during normal operation. Unlike basic rubber stops that rebound unpredictably, Eibach’s micro-cellular elastomer offers tremendous deflection capacity with near-zero lateral expansion. That means consistent compression behavior, less side loading on shocks, and smoother recovery after impact. Each bump stop is precision-molded for consistent durometer and rate, ensuring reliable, repeatable performance whether you’re taking hits off-road or running curb transitions on track.

The Science of Progressive Bottoming Control In a properly tuned suspension, bump stops serve a dual purpose — protecting components and influencing how energy is managed at full compression. The Eibach Elastomeric Bump Stop doesn’t just prevent metal-to-metal contact; it adds progressive resistance to create a controlled deceleration curve. This progressive bottoming behavior keeps your vehicle stable even during hard impacts or bottom-out events, helping maintain traction and chassis composure when suspension travel is fully used. On off-road trucks and race vehicles, this control translates to less rebound shock, faster recovery, and greater shock longevity. By functioning as an auxiliary spring, this bump stop effectively extends your tuning range — letting you optimize shock valving and spring rates without overcompensating for harsh bottom-outs. Installation and Tuning Guidance Installation depends on your application — whether you’re integrating the bump stop into a coilover sleeve, a bypass can, or a factory-style strut assembly. Simply match the inner diameter to your shock shaft or bump can design and ensure proper clearance at full compression. For precision setups, Eibach recommends pairing bump stops with its ERS (Eibach Race Spring) or PRO-TRUCK shock systems for a balanced spring curve throughout the suspension cycle. The 1011 lb/in rate provides firm, controlled energy absorption ideal for performance street, track, and off-road use. ⚙️ Tuning Tip: Adjust bump stop preload and contact timing to fine-tune bottom-out progression. Earlier engagement will soften the impact load but reduce travel; later engagement increases stroke utilization with sharper end-stroke resistance. Built with Motorsport DNA Every component in Eibach’s elastomeric line is developed through real-world motorsport testing — from rallycross and Baja racing to road course competition. Each bump stop undergoes load-cycle, fatigue, and temperature testing to ensure reliability under repeated compression events. The material’s micro-cellular structure is engineered for long-term performance and resists degradation from oils, UV exposure, and heat — giving you a consistent tuning element you can rely on season after season.
