helper springs are a separate smaller spring that goes in line w/ the main spring...usually the spring rate is a lot lower..

the reason is that say u get in a situation where your suspension gets fully extended (ie max droop). if your spring is not long enough, it will basically have nothing holding it in place...bad.

so this smaller light spring doesn't really effect the handling of the car, but its there so that the main spring can be kept in place...
