What does Z71 mean in a GMC Truck?

Z71 is a designation used by General Motors for off-road-oriented trim packages on its GMC trucks. It typically appears in the model names of full-size trucks such as the Sierra 1500 and Sierra 2500HD. The Z71 package typically includes a number of features designed to enhance off-road performance, such as:

- A raised suspension for increased ground clearance

- All-terrain tires

- A locking rear differential

- Skid plates to protect the undercarriage

- A heavy-duty air filter

- Hill descent control

- Tow hooks

- Enhanced shocks

- Specialized badging and decals

Z71-equipped trucks are often marketed to outdoors enthusiasts and those who need a truck for more demanding tasks, such as towing or carrying heavy loads off-road. They typically come with a higher price tag than base models, but they offer increased capability and durability for those who need it.
