Eibach ERS Helper Spring - 2.50" x 3.00" x 11 lb/in - HELPER250
The Eibach ERS Helper Spring is designed to maintain main-spring position and coilover preload during full suspension droop, ensuring consistent handling and proper spring stack function. This 2.50" I.D., 3.00" length, 11 lb/in helper spring uses Eibach's flat-wire construction to deliver maximum travel with the smallest possible block height - ideal for performance coilover systems across road racing, drag racing, autocross, and custom suspension builds.
The HELPER250 collapses fully under load without influencing the main spring rate, keeping your primary spring seated and stable through aggressive suspension movement. Each spring is individually tested for accuracy and built to Eibach's world-class standards for precision and durability.
