the Z71 package includes as folows: The Z71 Suspension Package is highlighted by stamped A-arms and a 28mm front stabilizer bar. Firmer urethane jounce bumpers are used on all Z71 models in place of the softer rubber bumpers used on the available Sport 2WD suspension. Both Z71 2WD and 4x4 Suspension Packages have front torsion bars and independent front suspension. Both features help supply the legendary Z71 performance, handling and stance.
Additional Z71 Suspension Package features include:
Available on Extended and Crew Cabs
P265/70R-17 all-season blackwall tires (P235/75R-16 spare)

Front and rear chromed bumpers
Color-keyed grille with chrome center bar
4x4 models also have Insta-Trac 4x4, a front underbody shield and gas-charged monotube shocks (twin-tube shocks on 2WD models)
Z71 means "off road" package, as far as I know they are all 4x4's - thus the "off road" designation
Z71 is an option package offered through GMC dealers. The Z71 package is an off road add-on with 4x4 drivetrain and a better shock system to handle the bumps and dips of off road terrain.
Nope. Z71 vehicles are generally 4x4, not 2x4. Starting in 2007, GM started offering the Z71 package on 2wd Avalanche trucks. The badging will only say Z71 instead of Z71 4x4
That would be the 4L60E
