Eibach ERS Helper Spring 2.50in Dia 6.00in Length 5 lbs/in (HELPER250T)
The Eibach ERS Helper Spring HELPER250T is engineered to keep the main spring properly seated during full suspension droop while maintaining full primary spring performance. Its flat-wire construction allows for an extremely small block height, maximizing usable suspension travel and ensuring consistent preload control in demanding coilover setups.
This 6.00-inch helper spring is ideal for long-travel coilover systems used in road racing, autocross, drift, off-road, and custom suspension applications. Each spring is individually tested for accuracy, rate consistency, and long-term durability.
