The fully refreshed 2024 Chevy Silverado HD was officially unveiled last September, with GM showing off new exterior styling, a redesigned cabin, new tech goodies, and an updated powertrain, not to mention the new Silverado HD ZR2 off-roader. Now, GM Authority has learned that the new 2024 Chevy Silverado HD Custom will be available with the Z71 Off-Road package.
Prior to the 2024 model-year refresh, the Z71 Off-Road package was optional on all trim levels (WT, LT, LTZ, High Country) except Custom.
Tagged with RPO code Z71, the Z71 Off-Road package adds in a number of dirt-duty bits and pieces, including (relevant RPO codes listed in parentheses):
- Off-Road suspension with twin-tube Rancho shocks
- Hill Descent Control (JHD)
- Skid plates to protect the transfer case and oil pan (NZZ)
The Z71 Off-Road package is only available for the 2024 Chevy Silverado HD Custom in conjunction with four-wheel drive. Notably, the Z71 Off-Road package does not include a tire upgrade for Chevy Silverado HD Custom trim levels, as the Custom is already equipped as standard with LT275/65R20 all-terrain tires (RPO code QF9).
As a reminder, the 2024 Chevy Silverado HD Custom trim level is only available for 2500 HD configurations, and is not available for 3500 HD configurations.
Pricing information specific to the new Z71 Off-Road package is currently unavailable. However, GM Authority did recently uncover extensive MSRP information for the refreshed 2024 Chevy Silverado HD with regard to the various trim levels and configurations on offer. As GM Authority covered previously, pricing is now between $1,100 and $2,000 more expensive for 2024 Chevy Silverado HD models as compared to equivalent 2023 model-year vehicles. Check out our previous coverage for more information.
As for the specs, the 2024 Chevy Silverado HD is equipped as standard with the naturally aspirated 6.6L V8 L8T gasoline engine, which now connects to the Allison-branded 10-speed automatic transmission, as opposed to the GM six-speed automatic transmission equipped by gasoline-powered models prior to the refresh. Meanwhile, the optional 6.6L V8 L5P turbodiesel Duramax gets an output boost to 470 horsepower and 975 pound-feet of torque.
