Take Up Spring - 1-7/8X4IN 25LB

AFCO Dual Stage Coil-Over assemblies use two coil-over springs, a special nylon slider for small body shocks that fits between the two springs. Also, two special, thin-walled nuts are used to jam the slider assembly in order to “stage” suspension stiffness. When the slider assembly (located between the two springs) is free to slide on its shock, the Dual Stage assembly produces a combined spring rate softer than either rate of the two springs used
