{"product_id":"4340-forged-steel-crankshaft","title":"4340 Forged Steel Crankshaft","description":"The BTR forged crankshaft is a premium component crafted from robust 4340 forged steel, engineered for demanding street and race LS engines. Each crankshaft undergoes a core-hardening process using nitride treatment, which significantly boosts its strength, extends bearing life, and ensures exceptionally tight size tolerances, held to within +\/-.0002\".\n\nThis crankshaft offers versatility with multiple stroke options, including 3.622\", 3.900\", and 4.000\". Additionally, it provides choices for the reluctor wheel, with standard factory 24X and 58X tooth options, as well as an upgraded 24-tooth BILLET wheel available. The design incorporates a standard wet sump snout and a 6-bolt rear flange, facilitating easy installation with factory or aftermarket balancers, flywheels, and flexplates.\n\nKey features contributing to its performance and durability include a 2.100\" rod journal diameter and a .125\" radius on both connecting rod and main journals for increased strength. The oil holes are chamfered to promote improved oiling, and the counterweights feature a leading-edge chamfer and radius. BTR also offers balanced rotating assemblies for a complete performance solution. Note that installation requires an OEM-style, one-piece crank gear.","brand":"BTR","offers":[{"title":"Default Title","offer_id":52687277293880,"sku":"BTR FORGED CRANKSHAFT","price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662156546.webp?v=1784882135","url":"https:\/\/store.motormia.co\/products\/4340-forged-steel-crankshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
