{"product_id":"4340-forged-steel-crankshaft-3-875-stroke","title":"4340 Forged Steel Crankshaft, 3.875\" Stroke","description":"The Molnar Technologies crankshaft is meticulously crafted from 4340 forged steel, a material chosen for its exceptional strength and durability in high-performance applications. Each crankshaft undergoes a rigorous heat-treating process to significantly increase its tensile strength, ensuring it can withstand extreme operating conditions. To further enhance its resilience and lifespan, the crankshaft is shot-peened, a process that refines the surface texture to improve fatigue life, and then nitrided for superior wear resistance.\n\nThis specific crankshaft is designed for SB Chevy engines and features a 3.875-inch stroke, a 400 main bearing journal diameter of 2.649 inches, and a 2.100-inch rod journal diameter. The rear main seal is a two-piece design. Molnar Technologies ensures the quality and integrity of each crank through 100% magnetic particle inspection, guaranteeing against cracks and holding all components to the tightest tolerances found in the racing industry.","brand":"Molnar Technologies","offers":[{"title":"Default Title","offer_id":52662991683896,"sku":"MOL-400-3875CB6F-585","price":1020.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687505669.jpg?v=1784322558","url":"https:\/\/store.motormia.co\/products\/4340-forged-steel-crankshaft-3-875-stroke","provider":"MOTORMIA","version":"1.0","type":"link"}
