Fine-tune your suspension’s performance with the Eibach 70 Durometer Spring Rubber, engineered to deliver controlled, progressive spring response and superior handling precision. Designed to fit 5.0-inch outside diameter coil springs, this green polyurethane insert provides a balance between comfort and control—ideal for setups requiring moderate rate adjustment without sacrificing ride quality.
