Spring Rubber C/O Extra Hard Yellow

The INTEGRA SHOCKS Spring Rubber C/O Extra Hard Yellow is a precision polyurethane shock absorber spring designed for high-performance suspension systems. This extra-hard yellow spring rubber (part number 310 3017-62) fits spring coil diameters from 2.5 to 2.625 inches and delivers 1.5 inches of cushioning height, making it ideal for applications demanding superior load support and vibration isolation in demanding tactical or automotive environments.

Constructed from durable polyurethane material, this extra-hard compound provides enhanced durability and resilience compared to standard or medium-hardness alternatives. The yellow color designation is industry-standard notation for this hardness rating, allowing technicians and technicians to quickly identify the spring rubber's performance characteristics during installation or maintenance. At just 0.15 lbs and compact dimensions of 4.65 x 1.75 x 5.9 inches, the unit integrates easily into tight suspension spaces while maintaining structural integrity under load cycling.

This spring rubber is sold as an individual unit, making it suitable for replacement, repair, or restoration projects where precise spring specifications are non-negotiable. Users performing suspension overhauls, shock absorber servicing, or custom build work benefit from having exact-fit components on hand. The INTEGRA SHOCKS brand's focus on engineered elastomer solutions ensures that this rubber maintains consistent performance across temperature extremes and extended duty cycles without permanent deformation.

Spring rubber selection depends on matching both the coil diameter (2.5–2.625 in range) and the required hardness grade. The extra-hard yellow rating indicates this unit is engineered for applications where greater load capacity and reduced compression are priorities. Verify your current spring specifications before ordering to ensure compatibility with your suspension system.
