Coil Over (Only Fits 55mm Front Strut Clamp)","category":"Suspension > Coilovers","description":"H&R continues its innovative design and manufacture of new suspension technologies with the introduction of their Premium Performance Coil-Over Kits. Featuring black, hard-anodized aluminum front struts for strength and beauty, Premium Performance Coil-Over Kits ultimately reduce unsprung weight 30-40% over stock struts and lower an average of 1.0\" to 2.5\" for optimized performance and ride.\n\nBlueprinted as coil-overs (not just a modified shock body), the H&R units are hand-assembled in Germany by H&R Speziafedern under rigid ISO 9001 and German TÜV standards. Strict attention to the function of the complete suspension system is the number one design priority.\n\nLike the Coil-Over Suspension Kits, the Premium Performance Coil-Over Kits' threaded body means that the outside of the strut or shock tubes are threaded like a bolt. This allows the threaded spring perch to be moved up or down to fine-tune the ride height, further optimizing looks and handling. Available for popular Audi, BMW and Volkswagen applications, these coil-overs feature H&R's exclusive damper technology. Each shock is specifically engineered to work smoothly with the progressive rate springs.\n\nThe Premium Performance Coil-Over Kits pictured above represent a sample application. Coil-overs are engineered specifically for each vehicle and may combine different components than those pictured based on the vehicle's design.","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/HR_COILOVER_STOCK_IMAGE_a8da60ca-37b2-48a2-974e-31d775c6ffea.png?v=1782351519"],"price":1250.67,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-07-03T16:46:21.361Z"},"share_url":"https://firestarter.network/l/lst_3W9tpOGD","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
