These Galvanised Slipper Spring Shackles by Ark are zinc-plated and come in a twin pack. The pack contains 2 x 3 1/2" x 1/2" bolts and nylock nuts. Ark front and rear leaf spring hangers form a critical link by keeping the springs (suspension) attached to the trailer. They also require regular maintance inspections.
