What does the Z71 package include?

The Z71 Off-Road Package typically adds upgraded suspension, protective underbody shielding, rugged tires, and off-road electronics to GM trucks and SUVs. In short, it enhances capability off pavement with a combination of hardware and driving aids. Exact contents can vary by model year and vehicle, so always check the window sticker or build sheet for the specific car.


Overview of the Z71 package


The Z71 designation is GM’s badge for an off-road-oriented package offered on several Chevrolet and GMC models. It is designed to improve traction, durability, and capability when venturing off-road, while often including distinctive styling touches. Availability and exact components differ by model and year, so prospective buyers should confirm what’s included on the exact vehicle they’re considering.


Typical components you’ll find


Below is a general guide to features commonly associated with the Z71 Off-Road Package across GM trucks and SUVs in recent years. Variations by model-year or trim are possible.



  • Off-road tuned suspension, often including upgraded shocks (such as Rancho shocks) to improve damping on rough terrain

  • 2-speed transfer case for enhanced 4x4 capability and crawl control in challenging terrain

  • Electronic locking rear differential for improved traction in low-traction conditions

  • Front skid plate and additional underbody protection to shield vital components

  • All-terrain tires mounted on larger, rugged wheels (sizes typically in the 18–20 inch range)

  • Front recovery hooks and, in some configurations, rear recovery hooks

  • Hill Descent Control and off-road drive modes to optimize throttle, braking, and traction

  • Distinctive exterior badging and interior accents to indicate the Z71 trim


Note: Some items, such as the locking differential or specific tire/wheel combinations, may be optional or replaced with alternative equipment depending on the model and year. Always verify the exact contents with the dealer or on the vehicle’s build sheet.


Model-specific notes


Silverado 1500 and Sierra 1500 variants typically include the core off-road hardware listed above, with differences in tire options, wheel design, and available sub-features based on trim level and production year.


SUV applications such as the Tahoe/Suburban and GMC equivalents may share many of the same components, but the exact package may be labeled differently or offered with slightly different hardware sets depending on the SUV’s size, platform, and year. Always confirm the current brochure or window sticker for precise contents.


How to verify what’s included when shopping


To ensure you’re getting a true Z71 Off-Road Package, check the vehicle’s documentation or window sticker for the exact list of features. Look for explicit mentions of: Z71 Off-Road Package, off-road suspension, skid plates, electronic locking rear differential, hill descent control, and all-terrain tires. If you’re dealer-shopping, ask for the build sheet or a VIN-specific equipment list, as some items can be language-dependent or year-specific.


Why the Z71 matters for buyers


For buyers prioritizing off-road capability without stepping up to a heavy-axis off-road model, the Z71 offers a balanced mix of transferable hardware and practical features. It signals enhanced protection and drivetrain capability—plus a visual cue that the vehicle is equipped for rougher terrain—while typically aligning with popular trims and configurations.


Summary


The Z71 Off-Road Package is GM’s badge for a bundle of off-road enhancements across Chevrolet and GMC pickups and SUVs. It generally includes upgraded suspension, a two-speed transfer case, an electronic locking rear differential, underbody protection, all-terrain tires, recovery hooks, off-road drive modes, and distinctive badging. Exact contents vary by model year and vehicle, so verify the specific build sheet to know exactly what’s included on a given Z71-equipped vehicle.

Is the Chevy Z71 package worth it?


The Chevy Z71 package is worth it if you need more off-road capability, as it adds features like skid plates, off-road shocks, and a two-speed transfer case. However, it may not be worthwhile if you don't plan to drive on rough terrain, as the added cost and features might not be necessary for your needs. The value depends entirely on your intended use of the vehicle.
 
Benefits of the Z71 package

  • Improved off-road performance: The package includes features designed to handle rough terrain, such as shock absorbers and a durable suspension system, notes Pat McGrath Chevyland. 
  • Underbody protection: Skid plates are strategically placed to protect the engine, transfer case, and fuel tank from rocks and other debris. 
  • Enhanced capability: It includes a heavy-duty air filter to prevent excessive dust from entering the engine and a Hill Descent Control system for managing descents on steep slopes. 
  • Versatile drivetrain: A two-speed Autotrac transfer case allows you to switch between different drive modes (2WD, 4WD, and Neutral) to suit various road conditions and improve fuel economy or for towing. 

Considerations before buying
  • Intended use: If you primarily drive on paved roads and in urban areas, the added cost and features of the Z71 package are likely unnecessary. 
  • Alternative packages: For extreme off-roading, other packages or models might offer more specialized features. The Z71 package is a versatile off-road option, but not necessarily the most extreme. 
  • Customization: Some buyers prefer to buy the standard model and add their own aftermarket parts to achieve a custom setup. 



What is the difference between Z71 and normal?


The Z71 package includes Rancho brand shocks, which provide better suspension for bumpy trails and other rough terrain. An underbody shield and brushed metal sill plates also protect against all those bumps along the way.



What is the difference between a 4x4 and a Z71?


A Z71 is an off-road package for a Chevrolet 4x4, not a different drivetrain. While all Z71s are 4x4, a standard 4x4 lacks the Z71's specific enhancements like off-road tuned shocks, skid plates, and potentially a locking rear differential, along with its distinct styling cues.

Z71 package

  • Off-road enhancements: Includes Rancho shocks, skid plates, and an off-road-tuned suspension for better performance on rough terrain. 
  • Traction control: Can come with an automatic locking rear differential and an advanced transfer case that provides a low-gear range for off-roading. 
  • Driver aids: May include features like Hill Descent Control. 
  • Distinct styling: Features Z71 decals, specific wheels, and a painted front bumper. 

Standard 4x4
  • Drivetrain: Has a four-wheel drive system, but with a standard suspension system not specifically tuned for off-road use. 
  • Traction: Often has a standard, open rear differential, which can lead to getting stuck if both wheels on one side lose traction. 
  • Styling: Typically has standard bumpers and wheel designs, without the Z71 specific features or decals.

How to choose
  • Choose a standard 4x4 if you want four-wheel drive for occasional use and a lower price point. 
  • Choose a Z71 if you plan to do more serious off-roading, as it comes with the necessary equipment to handle rough terrain more effectively.
