Eibach ERS Helper Spring 3.00in Dia (HELPER300TS)
The Eibach ERS Helper Spring HELPER300TS is designed to keep the main spring properly seated during full suspension droop without affecting the primary spring's rate or travel. Built using Eibach's proven flat-wire construction, this helper spring compresses to an extremely small block height, maximizing usable suspension travel and ensuring consistent preload control in demanding coilover applications.
This model fits coilover systems using a 3.00 inch inside-diameter spring and is ideal for road racing, autocross, drift, off-road, and custom suspension setups where maintaining spring position is essential. Like all Eibach ERS Helper Springs, it is individually tested for accuracy and long-term durability.
