Intended for the most demanding applications.\nBillet 4340 Steel Crank - NISSAN SR20, 3.583\" Stroke, KNIFE-EDGED COUNTERWEIGHTS.\nCrankshaft must be balanced to match your specific Rods and pistons.\nNISSAN SR20\n\u003cp\u003eThe Eagle Nissan SR20 4340 Billet Crankshaft is engineered for demanding high-performance and competition applications. Manufactured from premium 4340 billet steel, this crankshaft uses knife-edged counterweights to reduce rotating weight and improve engine response. Its 3.583-inch stroke is designed for Nissan SR20 engine builds requiring increased displacement and durable bottom-end performance.\u003c\/p\u003e\u003cp\u003eStrength and surface durability are enhanced with .125-inch fillet radiuses, a nitrided surface, and a micropolished finish. Because the larger fillet radiuses require additional clearance, chamfered or narrowed main and rod bearings are required during installation. The crankshaft must be professionally balanced to match the exact connecting rods and pistons used in the engine assembly.\u003c\/p\u003e\u003cp\u003eThis Eagle crankshaft is intended for automotive use and is not intended for street emissions certification. Professional engine machining and assembly are recommended to verify bearing clearance, crankshaft alignment, balance, and compatibility with the complete rotating assembly. Fitment is intended for Nissan SR20 applications; confirm engine configuration and required supporting components before purchase.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eagle 4340 billet steel crankshaft with knife-edged counterweights for Nissan SR20 applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBillet 4340 Steel Construction: Provides high strength and durability for demanding performance and competition engine applications.\u003c\/li\u003e\n\u003cli\u003eKnife-Edged Counterweights: Reduces rotating weight to support improved engine response and high-rpm performance.\u003c\/li\u003e\n\u003cli\u003e3.583-Inch Stroke: Designed for Nissan SR20 engine builds seeking increased displacement potential.\u003c\/li\u003e\n\u003cli\u003e.125-Inch Fillet Radiuses: Enhances crankshaft strength while requiring chamfered or narrowed bearings for proper clearance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Eagle","offers":[{"title":"Default Title","offer_id":67646659657980,"sku":"3SR235835365","price":1725.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/c9d10579dcb4c4b441c1af50f4d0e585.png?v=1791170180","url":"https:\/\/diycustoms.store\/products\/eagle-nissan-sr20-4340-billet-crankshaft-with-3-583-inch-stroke-and-knife-edged-counterweights","provider":"diycustoms.store","version":"1.0","type":"link"}
