This aluminum spring seat fits between upper and lower 60mm springs to "join" them together. Typically you would have a main spring on top and a tender or helper spring on the bottom (or vice-versa). The spring joiner, or locator ring, fits between the springs with a retaining lip on the inside. We like this design better than an outside spring joiner because it's lighter and there's no material sitting on the outside where a tire might come in contact with it. These are priced per each.
