The 2024 Silverado HD lineup has been updated with the inclusion of the HD ZR2 and HD ZR2 Bison, both of which provide proven racing technology and improved off-road capacity. The unique ZR2 Bison offers specialized equipment from American Expedition Vehicles, a premium off-road aftermarket manufacturer, for those who want to experience the ultimate in off-road ability during their expeditions.
“The all-new Silverado HD ZR2 and HD ZR2 Bison provide the off-road performance our customers have come to expect from a ZR2, with the towing and payload capabilities our HD customers demand,” said Michael MacPhee, director of Chevrolet Trucks Marketing. “They also expand the Silverado HD lineup, offering more choices for customers to find the perfect truck for work and off-road adventure.”

It also adjusts throttle response and transmission shifts, while the locking rear axle doesn’t have a speed limit.
The collaboration between HD ZR2 Bison and AEV has set a new standard for off-road performance.

IN FOCUS
The Multimatic spool-valve dampers used in the Silverado HD ZR2 are designed to provide optimal off-road capability while maintaining on-road comfort. These dampers were first used on the Colorado ZR2 racing program and were tested with Chad Hall Racing in the Best in The Desert off-road racing series. Compared to conventional shim-type dampers, the unique spool-valve design has three separate spools and offers unlimited tuning variability to control damping, resulting in more precise damping performance for greater control on and off the road.
The interior has been redesigned to have a ZR2 style.
The HD ZR2 and ZR2 Bison come with the newly redesigned interior of the 2024 Silverado HD lineup. It’s built for a blend of premium materials, excellent work-ready functionality, and next-level technology integration. The cabin offers features that HD truck buyers expect with an emphasis on off-road prowess, just like the Silverado 1500 ZR2.
The Jet Black and Graystone leather-appointed surfaces of the interior complement its dark trim accents. The materials used in the interior are also easy to clean after a day of off-road driving.
The instrument panel of the HD ZR2 and ZR2 Bison boasts a best-in-class 13.4-inch-diagonal infotainment screen and an expansive 12.3-inch-diagonal configurable driver information center. They serve as the driver’s command center and are canted towards the driver, enhancing the command center perspective. Smart off-road technology like the available 15-inch Head-Up Display with an off-road inclinometer and HD Surround Vision is also available.
The HD ZR2’s interior space is efficiently designed with a redesigned wireless phone charger area and a flow-under console that offers the spaciousness of a bench seat while retaining the functionality of a center console.
