Eibach Helper Spring, 2.50" I.D., Individual

Sometimes called Tender Springs*, these soft springs are used on suspensions which can travel farther than the chassis spring. When the suspension droops, these springs expand and take up the slack between the chassis spring and the spring perch. This keeps the chassis springs centered on the perch and prevents the ride height from suddenly changing.

These short coils have a very low spring rate (11 pounds per inch) and are coil bound as soon as the suspension is loaded, so they will not affect the rate of your chassis springs. The 3" free length compresses to a solid 1/2" (13mm) thick spacer under just a 28 pound load. This size is designed for use with 2 1/2" ID coilover springs. Requires the use of a Coupling Spacer (Part No. 1902-2.50-SPACER, sold separately). Sold individually.

* Note: Eibach also makes a line of Tender Springs, which have rates from 94 to 3600 pounds. Those "true" tender springs are designed to affect the spring rate, while these Helper Springs do not.
