{"product_id":"sportsryder-rear-coil-spring-set","title":"SportsRyder Rear Coil Spring Set","description":"The Pedders coil spring set is engineered for 2004-2006 Pontiac GTO models to provide a balanced upgrade in handling and load-carrying ability while retaining factory ride height. This package combines heavy-duty rear springs, featuring a 5.7 kg\/mm spring rate, with SportsRyder front springs that utilize a 3.3 kg\/mm rate. The rear coils feature a specialized mini-bloc design to ensure consistent performance and durability.\n\nManufactured in Victoria, Australia, these springs meet ISO 9001 and QS9001 standards. Each spring undergoes a rigorous multi-step production process including hot-forming, oil-bath quenching, slow oven tempering, shot peening, and scragging. This manufacturing precision results in a loaded height tolerance of only +\/-2mm, ensuring predictable suspension geometry. All components are finished with a durable powder-coat.\n\nInstallation requires two rear springs per vehicle. Please note that the front springs (part numbers 2142L and 2142R) are sold individually, and both sides are required to complete the front set.","brand":"Pedders","offers":[{"title":"Default Title","offer_id":52663235084600,"sku":"2142 \/ 7643","price":152.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687523094.jpg?v=1784325203","url":"https:\/\/store.motormia.co\/products\/sportsryder-rear-coil-spring-set","provider":"MOTORMIA","version":"1.0","type":"link"}
