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

Features

  • Constructed from high-tensile-strength 4340 chromoly for increased strength over stock
  • Cold roll-formed splines for improved durability under load
  • Advanced induction coil heat treating for consistent strength and wear resistance
  • Cut-to-length design allows precise fitment to your specific housing
  • Bolt-in design for a direct, factory-style installation
  • Backed by a limited lifetime warranty against manufacturing defects

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.
