The 2023 Chevy Silverado 1500 introduces just a handful of changes and updates over the fully refreshed 2022 model year, once again offering the high-performance Chevy Silverado ZR2. Unfortunately, it’s looking like new examples of the ZR2 off-roading trim level will be few and far between, as GM Authority has learned that the 2023 Chevy Silverado ZR2 will be extremely constrained throughout the model year.
According to GM Authority sources, the 2023 Chevy Silverado ZR2 will be built in very low numbers, with just 5 percent of the original 2023 Silverado ZR2 unit total set to be produced.
It’s currently unclear why this constraint was put in place. However, the constraint is not related to the ongoing global microchip shortage, nor is it related to a supplier issue.
Developed in collaboration with Chad Hall Racing, the Chevy Silverado ZR2 is equipped with a range of off-road-ready equipment and features that give it the prowess and agility needed to hit the trail with confidence. This includes suspension upgrades with MultiMatic DSSV dampers, which are paired with uniquely tuned springs that increase suspension travel front and rear.
The Silverado ZR2 also features 33-inch off-road MT tires, front and rear e-lockers, a unique skid plate package, and a new high-approach front bumper that enhances approach angle by 31.8 degrees. Ground clearance is set at 11.2 inches, while the break-over angle is 23.4 degrees and departure angle is 23.3 degrees.
Under the hood, the Chevy Silverado ZR2 features the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque. Output is routed to the full-time four-wheel drive system through the GM 10-speed automatic transmission.
With regard to the trim level cadence, the Chevy Silverado ZR2 slots in between the Chevy Silverado LT Trail Boss and Chevy Silverado LTZ.
