Important Notes

  • A replacement CV front driveshaft is recommended for extended high speed use in 4x4 high or AUTO 4x4. GM vehicles with selectable 4x4 high and Auto 4x activation (Auto Trac) can use p/n 51256 (measures
  • 37.81" from U-joint center to end of slip joint.) 2010 to current models with a 6spd automatic transmission or vehicles with All Wheel Drive will require p/n 51257 - (measures 36.81" from U-joint center to end of slip
  • joint.). The K1142 / 51907 includes p/n 51256 and required differential brackets.
  • Due to variations in front bumper valance types on Avalanche and Z71, 33" x 12.50 tires may be required.
  • OE wheels will not fit. 07-13 models require 17" or larger diameter wheels.
  • Vehicle will require alignment after kit is installed.
