Spring Rubber 2.5in 70 Durometer Green

The Spring Rubber 2.5in 70 Durometer Green from Eibach is a precision elastomer component designed for suspension tuning and vibration isolation in high-performance automotive applications. Whether you're building a lowered street car, track-focused platform, or professional fabrication project, this spring rubber serves as a critical buffer between chassis components and vehicle dynamics. Mechanics and enthusiasts rely on Eibach's engineering to fine-tune ride quality, absorb road feedback, and protect underlying suspension geometry during aggressive driving or sustained load conditions.

At 70 durometer hardness, this green elastomer strikes an ideal balance between compliance and durability—firmer than soft isolators yet responsive enough to handle shock and harmonics without bottoming out. The 2.5-inch diameter profile accommodates standard suspension mounts, coil-over towers, and chassis brackets across popular platforms. Eibach's material formulation resists compression set, maintains elasticity across temperature extremes, and delivers consistent performance over thousands of heat cycles. This durometer rating works exceptionally well for independent coil systems, adjustable suspension kits, and OEM-to-upgrade transitions where factory rubber has degraded or lost its rebound characteristics.

Technicians and fabricators working on sports cars, muscle cars, and modified trucks frequently specify the Spring Rubber 2.5in 70 Durometer Green when replacing worn isolators or upgrading to performance coil-over systems. Installation is straightforward—simply press or bolt the rubber into existing suspension towers, subframe mounts, or custom chassis brackets. The 0.36-pound weight makes handling during installation hassle-free, while the compact 7.5 x 1.55 x 9.05-inch dimensions ensure it fits standard suspension architecture without requiring frame modification. For anyone seeking OEM-grade durability combined with the performance characteristics of aftermarket isolation, Eibach's green durometer rubber delivers both reliability and tuning flexibility.
