The 250 lb springs are 11\" tall and intended exclusively for drag racing applications with significant vehicle weight reduction, providing excellent front-end lift and weight transfer for improved traction. The hybrid front coil-over system allows a 0–3\" adjustable drop, while the rear springs offer 1\" or 2\" lowering options to fine-tune stance. Viking’s shocks provide 19 compression and 19 rebound settings, letting you dial in suspension performance for street, strip, or cornering with simple knob adjustments—no tools required. The bolt-in design eliminates the need for welding or a spring compressor for the front, and optional Spanner Wrench and Thrust Bearing Kits make height adjustments smoother. This setup is purpose-built for drag racing performance and is not recommended for street handling applications.","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":47848870150365,"sku":"UMIGBF250-1","price":2153.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/3758\/1491\/files\/00f527e23fd792968744dd3ed79073e4L.jpg?v=1777070070","url":"https:\/\/hellhoundperformance.store\/products\/umi-performance-78-88-gm-g-body-spring-shock-lowering-kit-1in-rear-250lb","provider":"Hellhound Performance","version":"1.0","type":"link"}
