The Yukon YAGM11.5-30-40.25 Rear Axle Shaft is built as a stronger-than-stock replacement that adds peace of mind without forcing you into an overly expensive upgrade. It’s designed for 2011-2018 Silverado and Sierra 2500HD and 3500HD models running the GM 11.5 inch differential. Yukon uses high-quality alloys and modern heat-treating processes to deliver durability you can feel when towing heavy trailers or loading the bed to capacity. The cut-to-length spline design gives installers flexibility while still maintaining a precise fit. This makes it a great solution for replacing a worn or damaged factory axle without unnecessary modification. If you want reliable strength that still makes sense for a daily-driven work truck, this axle checks all the right boxes.\u003c\/p\u003e\n\u003ch4\u003eDesigned To Match Factory Fit With Added Strength\u003c\/h4\u003e\n\u003cp\u003eThis Yukon rear axle shaft is engineered as a direct replacement for GM part number 20920663, ensuring proper fitment in GM 11.5 inch full-float differentials. It features a 30 spline configuration and a long spline length that can be trimmed to fit axle lengths ranging from 35 to 40.25 inches. The shaft is manufactured from 4340 chromoly, offering increased tensile strength over standard factory materials while remaining cost effective. A 4.760 inch flange outer diameter ensures compatibility with factory hub and brake components. Yukon’s heat-treating process improves durability in high-stress areas, which is critical for trucks that tow, haul, or operate under constant load. This axle is intended for 2011-2018 GM 2500HD and 3500HD platforms, making it a straightforward solution for stock replacements or mild performance upgrades. It’s a well-balanced option for builders who want improved reliability without moving into extreme race-only components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 GM Silverado\/Sierra 2500HD\/3500HD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2011-2018 GM Silverado and Sierra 2500HD\/3500HD\u003c\/li\u003e\n\u003cli\u003eDesigned for use with GM 11.5\" rear differentials\u003c\/li\u003e\n\u003cli\u003eDirect replacement for GM part number 20920663\u003c\/li\u003e\n\u003cli\u003eAxle length can be cut from 40.25\" down to 35\"\u003c\/li\u003e\n\u003cli\u003eUses 30 spline configuration for full-float setups\u003c\/li\u003e\n\u003cli\u003eConstructed from 4340 chromoly for added strength\u003c\/li\u003e\n\u003cli\u003eFeatures a 4.760\" flange outer diameter\u003c\/li\u003e\n\u003cli\u003eIdeal for towing, heavy-duty work, or mild performance upgrades\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended for proper trimming and fitment\u003c\/li\u003e\n\u003cli\u003eDoes not include studs, seals, or bearings\u003c\/li\u003e\n\u003cli\u003eWarranty details not provided by the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Yukon Gear And Axle","offers":[{"title":"Default Title","offer_id":68059952054545,"sku":"YUK-YAGM11.5-30-40.25","price":365.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/YA_20GM115-30-4025.jpg?v=1794702754","url":"https:\/\/gautoparts.com\/products\/yagm11-5-30-40-25-11-15-silverado-sierra-2500hd-3500hd-yukon-gear-rear-40-25in-axle-shaft","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
