The description of this item has been automatically translated. Fork springs progressively wrapped by YSS in a more solid design than the original. The YSS fork springs are made of high quality silicon spring steel. This reduces the thickness of the wire, which makes the spring more active and thinner, but at the same time effectively prevents the twisting of the spring. To minimize noise and improve oil flow into the fork, the springs are fully polished and ground at the top and bottom. For harley DAVIDSON 1130 VRSCR STREET ROD.
