These keeper / helper springs are suited to most coilovers. They are designed to compress fully under load, yet ensure your main coils remain captive when the suspension is unloaded. They are supplied as a kit of 2 springs and 2 retainers. Suit all standard coilovers (62-65mm ID springs). There are 2 different heights available. 50mm freestanding (20mm fully compressed) and 90mm freestanding (30mm fully compressed).
