The Silverado ZRX model would act as a step above the Colorado ZR2 in the Bowtie’s lineup of rugged pickups.
The tweaks for the Silverado ZRX allegedly include an overhauled suspension using the Multimatic DSSV dampers similar to the units on the Colorado ZR2, according to Muscle Cars & Trucks. Front and rear electronic-locking differentials would improve off-road traction.
The engine wouldn’t have any modifications to take power beyond other Silverado trims. At the moment, the top version makes 420 horsepower from a 6.2-liter V8.
Rumors hint that the Silverado gets an interior overhaul for the 2021 model year. If the ZRX arrives in 2022, it should benefit from these improvements.
