Integra Spring Rubber C/O Hard Blue 310 3017-57

Spring rubbers are critical suspension components that isolate vibration and manage load transfer during acceleration, braking, and cornering. A worn or inadequate rubber bushing compromises ride quality, increases NVH (noise, vibration, harshness), and can lead to premature suspension wear. This hard-durometer polyurethane offering delivers the responsive feel and durability that serious drivers demand from their suspension geometry.

The Speedthane Conventional formulation provides excellent resilience and resistance to oil and heat degradation, making it suitable for both street and track applications. The hard-compound construction resists deflection under load while maintaining structural integrity through repeated duty cycles.
