Eibach ERS Helper Spring 1.88in Dia 2.98in Length 12 lbs/in (HELPER188)
The Eibach ERS Helper Spring HELPER188 is engineered to maintain main-spring position during full suspension droop without affecting primary spring rate or travel. Using a flat-wire construction, this helper spring compresses to an extremely small block height, ensuring maximum usable travel while keeping the main spring properly seated in dynamic suspension setups.
Ideal for coilover systems that experience full droop - road racing, autocross, drift, off-road, and custom suspension builds - this helper spring provides consistent preload control and smooth suspension transitions. Each spring is individually tested for accuracy and long-term reliability.
