Also known as 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 very low spring rates (virtually zero) and are coil bound when the suspension is loaded. They will not affect the rate of your chassis springs. Approximately 1/4" long when compressed. Requires the use of Spring Dividers (Part No. 1877-60mm). Sold individually.
