{"product_id":"4-000-stroke-ls-main-1-piece-rear-main-forged-crankshaft","title":"4.000\" Stroke LS Main 1-Piece Rear Main Forged Crankshaft","description":"Eagle forged 4340 steel crankshafts offer maximum strength at an affordable cost. These cranks are constructed from certified 4340 steel using a non-twist forging process. They undergo a multi-stage heat treatment for enhanced strength and are then X-rayed, sonic tested, and fully nitrided for superior longevity. The journals are micro-polished to a 3 r.a. or better to maximize bearing life, and all journals feature a .125-inch filet radius for added strength, requiring narrowed bearings.\n\nThis crankshaft is specifically designed for Chevrolet Small Block applications and features an internal balance, a 4.000-inch stroke, and a 6.125-inch or longer rod length. It utilizes an LS main bearing type, a 1-piece rear main seal, and comes equipped with a 58-tooth reluctor wheel. Please note that rod and main bearings are not included with this crankshaft, and it requires narrowed bearings for installation.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872903557432,"sku":"EAG434740006100","price":1062.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-000-stroke-ls-main-1-piece-rear-main-forged-crankshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
