Tender springs (also called helper springs) work in conjunction with your main spring to maintain suspension geometry and prevent the main spring from becoming loose during droop. This allows for proper suspension travel while maintaining contact between all suspension components. Hyperco tender springs are a popular choice among racing teams and serious enthusiasts for circle track, road racing, and high-performance street applications.
