The AAM 40057071 is a new front left output axle shaft engineered for GM's 9.25 Inch Clamshell front axle assembly. Built with a 33-spline design, it's a direct-fit replacement for a broad range of 1999-2013 Chevrolet Silverado, GMC Sierra, Suburban, and Hummer 4WD/AWD trucks and SUVs. For 2007 and earlier applications, this shaft can also be used in combination with diff gear kit 74040363 to complete the service. As a new component rather than remanufactured or reconditioned, it's intended to restore reliable front-axle power delivery on high-mileage or damaged applications. Backed by AAM's limited one-year warranty, this shaft is a straightforward way to get your front differential output back in working order without guesswork on fitment, since it is specifically designed for the 9.25" clamshell front axle platform.

Features

  • New (not reconditioned) construction offers a fresh replacement instead of a worn-out core
  • 33-spline design matches GM 9.25" clamshell front axle for proper driveline engagement
  • Compatible with 2007 & earlier applications when paired with diff gear kit 74040363
  • Front left placement targets the exact side needing replacement, simplifying your order
  • One-year limited warranty backs your purchase for added peace of mind
