It is paired with TSP or K1 Technologies forged 4340 steel 6.125\" H-beam connecting rods and Wiseco 2618 forged 4.07\" pistons, available in -3cc Flat Top or -15cc Dish options with coated skirts. Clevite main and rod bearings are included, and the entire assembly is digitally spin balanced on a CWT balancer for smooth, trouble-free operation.\n\nKey specifications include the 4.00\" stroke crankshaft, 58x reluctor wheel, and H-beam connecting rods. Note that this is not a direct drop-in kit for a stock block; machine work is required to accommodate the longer stroke and oversized pistons. If using this assembly in a Gen 3 vehicle equipped with a 24x reluctor wheel, a Lingenfelter Crank Sensor Conversion Box (Part no. # L460065397) will be necessary.","brand":"Texas Speed \u0026 Performance","offers":[{"title":"Default Title","offer_id":52866431680824,"sku":"TSP-SS416BRA","price":3149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687712211.webp?v=1787907832","url":"https:\/\/store.motormia.co\/products\/4-00-forged-crankshaft-assembly-w-6-125-h-beam-rods-4-07-pistons","provider":"MOTORMIA","version":"1.0","type":"link"}
