{"product_id":"timbren-ur350-helper-spring-kit","title":"Timbren Ur350 Helper Spring Kit","description":"This SES Suspension Upgrade can be adapted to fit the rear suspension of most heavy-duty trucks equipped with leaf springs. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag, and help stabilize the load.","brand":"Timbren","offers":[{"title":"Default Title","offer_id":49423426257123,"sku":"T1KUR350","price":398.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/4410\/7491\/files\/ImageServerAPI_dad0baf2-2a51-4bd7-88f6-8794288c8a90.jpg?v=1784459477","url":"https:\/\/www.partsvia.com\/products\/timbren-ur350-helper-spring-kit","provider":"PartsVia.com","version":"1.0","type":"link"}
