Manufactured from 4340 chromoly with cold roll-formed splines and induction coil heat treating, this shaft is engineered to hold up under towing, hauling, and heavy-duty use where stock axle shafts are prone to twisting or breaking.\u003c\/p\u003e\u003cp\u003eIts cut-to-length design covers a range of finished lengths from 34.8\" to 38.8\", allowing it to be trimmed to match your specific axle housing rather than requiring a separate part number for every length variation. This makes it a practical option for custom builds, axle swaps, or replacing a broken shaft where exact stock length isn't readily available.\u003c\/p\u003e\u003cp\u003eThis shaft is bolt-in and does not include wheel studs, bearings, or seals - those are sold separately. Because GM changed the wheel bolt pattern on some 2011-and-later HD trucks, and because the GM 10.5\"\/11.5\" family spans many vehicle and axle housing variations, confirming your exact bolt pattern and required length before ordering is strongly recommended.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your GM truck with the Yukon YA WGM14T-30-38 axle.
