Spring Rubber 2.5in 80 Durometer Yellow

The Spring Rubber 2.5in 80 Durometer Yellow by Eibach is an essential suspension component engineered for performance-oriented vehicle builds and custom suspension tuning. Designed for mechanics and enthusiasts working on lowered platforms, coilover conversions, or custom spring rates, this isolator serves as a precision interface between your coil spring and suspension mount.

The 2.5-inch diameter profile fits most aftermarket and OEM spring platforms, making it a versatile choice for street cars, track builds, and restoration projects requiring suspension geometry refinement. At 80 durometer hardness, this yellow rubber isolator provides optimal compliance for vibration absorption while maintaining structural integrity under sustained load cycles. Eibach's precision manufacturing ensures consistent wall thickness and material composition, critical for preventing premature degradation under the cyclic stress of acceleration, braking, and cornering loads.

This isolator benefits builders upgrading to coilover kits, those installing variable-rate springs, or mechanics working on multi-stage suspension tuning where spring rates are frequent. Its compact design helps keep unsprung mass minimal, preserving your suspension's responsiveness and damping characteristics.
