{"product_id":"4-250-stroke-rotating-assembly-stroker-kit","title":"4.250\" Stroke Rotating Assembly Stroker Kit","description":"The Eagle EAG-52505-4185 is a high-performance rotating assembly stroker kit engineered for competition use. It is designed to work with 428 and 455 engine blocks, featuring a 4.250\" stroke to create a 468 cubic inch displacement.\n\nThis comprehensive kit includes a new forged 4340 steel crankshaft, forged 4340 H-beam connecting rods measuring 6.800\" with ARP 8740 capscrew rod bolts, and Mahle -22cc dish top pistons. It also comes with plasma-moly file fit rings and performance racing bearings.\n\nIt is crucial that all rotating assemblies are balanced prior to installation. Furthermore, assemblies balanced internally will necessitate a neutral balanced flexplate or flywheel and a harmonic balancer. All Eagle kits are supplied with file fit rings, which typically require filing to achieve the desired bore size.\n\nThe ESP Armor surface finishing process is exclusive to Eagle and is applied to the rods and cranks. This process creates an incredibly slick surface, reducing bearing friction, lowering oil temperature, decreasing windage losses, and enhancing corrosion resistance, ultimately leading to longer bearing life. Eagle offers a one-year limited warranty against breakage when ESP Armor is used on any 4340 steel crankshaft or H-beam rod.","brand":"Eagle","offers":[{"title":"Default Title","offer_id":52687897362744,"sku":"EAG-52505-4185","price":2899.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664194870.jpg?v=1784887144","url":"https:\/\/store.motormia.co\/products\/4-250-stroke-rotating-assembly-stroker-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
