Spring Rubber C/O 70A Green 1.0in Coil Space

The Spring Rubber C/O 70A Green 1.0in Coil Space by RE SUSPENSION is a precision elastomeric isolator designed for high-performance suspension systems and drivetrain assemblies. As a dedicated mechanic, you understand that spring rubbers serve a critical function: they dampen vibration transfer, reduce noise, and protect mounting points from metal-to-metal contact under load cycles. This green durometer rubber sits at 70A hardness—a proven sweet spot for automotive applications that demand both compliance and durability without sacrificing rigidity.

Engineered from vulcanized natural and synthetic rubber compounds, the Spring Rubber C/O 70A delivers consistent performance across temperature ranges typical in underhood and suspension environments. The 70A durometer rating provides optimal stiffness for 2.5-inch coil spring applications while maintaining flexibility to absorb harmonic vibrations generated during acceleration, braking, and cornering. Its 1.0-inch height creates a properly-spaced isolation layer between coil windings and mounting surfaces, preventing corrosion and extending component lifespan. The green coloration serves as a visual quality indicator and is standard across RE SUSPENSION's suspension isolation lineup, making field identification straightforward during installation or replacement intervals.

This component is essential for anyone rebuilding or refreshing a coil-over suspension system, whether for street applications, track use, or restoration work. Installation is straightforward: position the Spring Rubber C/O 70A between the coil spring base and the mounting perch, ensuring the 1.0-inch height aligns with your suspension geometry. It's sold individually, so verify your vehicle requires only one per coil or order multiple units for complete four-corner coverage. Compatible with most aftermarket and OEM coil spring assemblies using standard 2.5-inch spring diameters, this isolator belongs in any serious suspension rebuild to eliminate squeaks, reduce NVH, and protect long-term structural integrity.
