Flat Wire Helper Springs
High-Performance Flat Section Springs (Various IDs)
Constructed from flat-section wire, these helper springs are designed to fully compress into a minimal block height. This unique design maximizes the usable stroke of your damper while ensuring the main spring stays seated in the perch when the suspension is fully extended (full droop). Essential for coilover setups requiring maximum travel.
