The Silverado 1500 ZR2 variant excels at one specific type of off-road driving but is a bit of a letdown pretty much everywhere else. Certainly, Chevrolet equipped the ZR2 properly for slow rock-crawling. It's cool that it has grippy mud-terrain tires, beefy suspension dampers for supreme cushioning, and exhaust tips that are cleverly tucked in behind the bumper to avoid potential handshakes with boulders. The one-pedal off-road feature — allowing drivers to concentrate on the throttle pedal by stopping and holding the truck on inclines — is another neat trick.
However, the ZR2 feels like a fish out of water in other situations. It does not feel in its element driving off-road at speed in the way that the F-150 Raptor and Ram TRX do. Primary reasons for this shortfall include loose, unfocused steering that struggles to rein in the ZR2 at 40 mph-plus as well as relatively small tires. At 33 inches, they fall short of standard 35s on the Raptor and TRX, and their 275-mm width pales next to its rivals at 315 mm and 325 mm, respectively.
The ZR2's mud-terrain tires are also louder and heavier than traditional all-terrains, giving the ZR2 a noisy and uncomfortable ride on the road. The high-performance dampers could not cover up these deficiencies on-road or off- during our drive. Finally, Chevy kept the stock location of the lower rear shock mounts on the rear axle for the ZR2. Their low-hanging and exposed positioning is not a problem for normal driving and even some off-roading, but for hard-core off-roading we'd prefer to have them more safely tucked away from treacherous terrain.
