{"type":"firestarter.listing","listing":{"id":"lst_mSsyFawV","product_name":"H&R Sport Springs","category":"Suspension > Springs","description":"H&R Sport Springs are engineered, designed, and manufactured for improved handling, great looks (lowers the car just right), and a perfect ride.\n\nPrecision crafted in Germany, H&R Sport Springs use the finest German wire, and are fully heat-treated, shot-peened, pre-set with the Super-Blok process, powder-coated, and heat-cured. This exacting process ensures you a lifetime of no-sag, no-corrosion, unequaled performance.\n\nUnlike many suspension brands, H&R manufactures their own springs -- guaranteeing consistent results in a controlled, monitored atmosphere. While other suspension companies buy springs from several sources (which leads to inconsistent results across products), with H&R Sport Springs, youre buying the best - right from the mother ship. H&R was founded by Werner Heine and Heinz Remmen in the 1970's with a simple idea in mind; with improved suspension, vehicles would have more control and better handling.","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/28880-1.jpg?v=1783980380"],"price":483.65,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-07-14T01:31:33.199Z"},"share_url":"https://firestarter.network/l/lst_mSsyFawV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
