Fitment Notes
- Cut-to-length design fits housings requiring a finished axle shaft length between 34.8\" and 38.8\" — confirm your specific housing length before ordering
- This shaft uses a 3.562\" wheel bolt pattern; some 2011-and-later GM HD trucks use a larger bolt pattern, so verify your bolt circle before ordering on late-model applications
- Fits both the GM 10.5\" (14-bolt) and 11.5\" AAM rear differentials, which share compatible axle shaft specs despite the different ring gear sizes

Product Description
The Yukon YA WGM14T-30-38 is a high-performance cut-to-length rear axle shaft built for the GM 10.5\" (14-bolt) and 11.5\" rear differentials found in heavy-duty Chevrolet and GMC trucks, Suburbans, and full-size vans. 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.
Its 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.
This 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.
