{"product_id":"traxxas-4957r-progressive-rate-springs-ultra-shocks","title":"Traxxas 4957R Progressive Rate Springs: Ultra Shocks","description":"This is a Traxxas 4957R Progressive Rate Springs: Ultra Shocks. Features: Under light-duty driving, the progressive rate springs soak up the small bumps as a softer spring would, but when the conditions get rough and the jumps get big, the progressive rate springs step up to the challenge by getting firmer as the suspension is compressed. This resists the chassis from bottoming out from jumps to keep the chassis under control.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Factory New\u003cbr\u003e\u003cstrong\u003eOperational Status:\u003c\/strong\u003e \u003ca href=\"#\" title=\"This item is brand new from the factory.\"\u003eFunctional\u003c\/a\u003e\u003cbr\u003e\u003cstrong\u003eOriginal Box:\u003c\/strong\u003e Yes\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Traxxas\u003cbr\u003e\u003cstrong\u003eModel Number:\u003c\/strong\u003e 4957R\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCategory 1:\u003c\/strong\u003e Other Scales - RC\u003cbr\u003e\u003cstrong\u003eCategory 2:\u003c\/strong\u003e Suspension \u0026amp; Steering\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eThe Trainz SKU for this item is P12071664. \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size: 6px !important; color: #d3d3d3 !important; line-height: 8px !important;\"\u003eTrainz Product Id: 12071664\u003c\/span\u003e","brand":"Traxxas","offers":[{"title":"Default Title","offer_id":20167670562938,"sku":"P12071664","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1260\/4747\/products\/3879578.jpg?v=1678294929","url":"https:\/\/www.trainz.com\/products\/traxxas-4957r-progressive-rate-springs-ultra-shocks","provider":"Trainz","version":"1.0","type":"link"}
