Spring Rubber C/O Hard Red 1-1/4in Tall

The Spring Rubber C/O Hard Red 1-1/4in Tall by INTEGRA SHOCKS is a precision polyurethane elastomer designed for shock absorption and vibration damping in suspension assemblies. Built for engineers, mechanics, and industrial equipment specialists who demand reliable spring isolation, this hard-durometer rubber component fits springs measuring 2.5 to 2.625 inches in diameter. Its compact 1.25-inch height makes it ideal for applications where space constraints require a low-profile damping solution without compromising load capacity or performance longevity.

Manufactured from high-grade polyurethane in a hard formulation, this spring rubber delivers superior durability and resistance to compression set compared to softer elastomers. The red color identification standard aids in quick inventory management and visual verification during assembly. Hard-durometer polyurethane excels at maintaining structural integrity under sustained load cycles, resisting oil degradation, and performing across wide temperature ranges typical of automotive, industrial machinery, and heavy equipment environments. The C/O (center opening) design accommodates spring coils while distributing pressure evenly, reducing noise transmission and extending both the spring and mounting surface lifespan.

This component is essential for technicians rebuilding suspension systems, shock absorber assemblies, or OEM equipment requiring ISO-certified elastomer isolation. Compatibility spans coil springs in the 2.5 to 2.625-inch range, making it a direct replacement for worn or degraded rubber isolators in trucks, commercial vehicles, industrial presses, and vibration control rigs. Installation is straightforward: position the spring rubber between the spring base and mounting surface, ensuring the center opening aligns with the coil axis. For optimal performance, verify spring diameter before ordering and inspect mounting hardware for corrosion that may affect seating.
