Built for demanding performance applications, it combines a strong non-twist forging with a nitrided surface and micropolished journals for durability, wear resistance, and dependable operation under high engine loads.\u003c\/p\u003e\u003cp\u003eThis Eagle crankshaft features .125-inch fillet radii to improve strength and fatigue resistance. Because of the enlarged fillet design, chamfered or narrowed connecting rod bearings are required for proper clearance. The crankshaft must be professionally balanced to match the specific connecting rods and pistons used in the engine assembly. It is intended for automotive applications and is not approved for use on pollution-controlled street vehicles where applicable.\u003c\/p\u003e\u003cp\u003eFitment includes select 1990-1992 Mitsubishi Eclipse models, 1990-1992 Eagle Talon models, and the 1990 Plymouth Laser equipped with the compatible 4G63 engine and 6-bolt configuration. Always verify engine generation, rear flange style, bearing requirements, and rotating assembly specifications before installation. Professional machining, balancing, and assembly are recommended to ensure correct clearances and reliable performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eagle forged 4340 steel 4G63 crankshaft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e Brand: Eagle; Part Number: 2034655900A6; Engine Application: Mitsubishi 4G63; Stroke: 88mm; Material: Forged 4340 steel; Rear Flange: 6-bolt; Fillet Radius: .125 inch; Surface Treatment: Nitrided and micropolished.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eForged 4340 Steel: Provides high strength and durability for demanding performance and racing applications.\u003c\/li\u003e\n\u003cli\u003eNon-Twist Forging: Helps maintain crankshaft integrity under high load and high-RPM operating conditions.\u003c\/li\u003e\n\u003cli\u003eNitrided and Micropolished Surface: Improves journal wear resistance and promotes a smooth bearing surface.\u003c\/li\u003e\n\u003cli\u003e.125-Inch Fillet Radii: Enhances crankshaft strength while requiring chamfered or narrowed bearings for proper clearance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitments:\u003cbr\u003e\n1990 Eagle Talon TSi\u003cbr\u003e\n1990 Mitsubishi Eclipse GS\u003cbr\u003e\n1990 Mitsubishi Eclipse GSX\u003cbr\u003e\n1990 Plymouth Laser RS\u003cbr\u003e\n1991 Eagle Talon TSi\u003cbr\u003e\n1991 Mitsubishi Eclipse GS\u003cbr\u003e\n1991 Mitsubishi Eclipse GSX\u003cbr\u003e\n1991 Plymouth Laser RS\u003cbr\u003e\n1992 Eagle Talon TSi\u003cbr\u003e\n1992 Mitsubishi Eclipse GS\u003cbr\u003e\n1992 Mitsubishi Eclipse GSX\u003cbr\u003e\n1992 Plymouth Laser RS\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: t\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":67646938939644,"sku":"2034655900A6","price":944.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/d3b33fa9d2b6d86c03976fb5d3f77395.png?v=1791182442","url":"https:\/\/diycustoms.store\/products\/eagle-4g63-88mm-stock-stroke-forged-4340-steel-crankshaft-6-bolt-rear-flange-2034655900a6","provider":"diycustoms.store","version":"1.0","type":"link"}
