Spring Rubber 5in Dia. 60A Purple

The RE SUSPENSION Spring Rubber 5in Dia. 60A Purple (Part Number RE-SR500-1500-60) is a precision polyurethane elastomer component engineered for suspension isolation and vibration damping in automotive applications. Manufactured from durable 60-durometer polyurethane, this 5-inch diameter spring rubber isolator delivers consistent load absorption across a broad temperature range, making it ideal for heavy-duty suspension modifications, custom vehicle builds, and performance tuning where rubber isolation prevents metal-to-metal contact and noise transmission.

With a 1.5-inch height and 60A durometer rating, this component balances compliance and load-bearing capacity. The 60A hardness specification provides moderate flex—softer than harder compounds but firmer than ultra-compliant grades—allowing it to absorb high-frequency vibrations while maintaining structural support under sustained compression. The vibrant purple color aids in visual identification during assembly and maintenance. Weighing 1.16 pounds with compact dimensions of 5.65 x 2 x 5.7 inches, this isolator integrates seamlessly into suspension towers, engine mounts, and frame-to-body isolation points without adding significant mass or bulk to your platform.

Mechanics and fabricators working on lifted trucks, off-road builds, lowered vehicles, and custom suspension systems rely on RE Suspension spring rubbers to reduce harshness transmitted through the chassis, minimize brake dive and body roll, and protect adjacent components from shock loads. The purple durometer rating suits applications requiring moderate stiffness without sacrificing ride comfort—common in street-tuned suspensions, motorsport platforms, and vehicles operating across varied terrain. Whether upgrading a factory suspension assembly or engineering a complete custom setup, this 5-inch spring rubber isolator provides the engineered elasticity professional builders and serious enthusiasts demand.
