Spring Rubber Tall C/O 15lb Red

The Spring Rubber Tall C/O 15lb Red from RE SUSPENSION is a precision polyurethane isolator engineered for custom suspension tuning and vehicle modifications. This component serves as a critical bump stop or spring isolator for builders seeking fine-tuned ride quality and suspension geometry control. Whether you're lowering a sports car, adjusting spring rates on a track-focused platform, or fine-tuning a lifted truck, this tall-profile rubber isolator provides the compliance and damping characteristics needed to dial in handling without introducing harshness or unwanted noise into the chassis.

Constructed from premium polyurethane, the Spring Rubber Tall C/O 15lb Red features a durable red compound specifically formulated for springs ranging from 2.5 to 2.625 inches in diameter. Its 1.25-inch height classification and tall profile design make it ideal for applications requiring additional suspension travel cushioning or preload adjustment. The 15-pound spring rate rating indicates this isolator is engineered to complement mid-to-firm spring setups, offering progressive compliance that absorbs minor vibrations while maintaining structural support under load. The compact 3.75 x 1.5 x 3.75-inch footprint ensures easy integration into standard spring tower locations on most platforms.

Performance enthusiasts and suspension technicians favor RE SUSPENSION isolators for street and road-course applications where OEM rubber has deteriorated or where custom rates demand upgraded compliance materials. This spring rubber is sold individually, allowing builders to replace worn isolators or upgrade specific corners of their suspension independently. Installation is straightforward—position between the spring and its seat, ensuring the rubber sits flush and centered to prevent binding or premature wear. Compatible with coil-over systems, aftermarket spring kits, and factory suspension rebuilds across most automotive platforms.
