We have learned from sources familiar with the matter that the upcoming Chevy Silverado ZR2 will come equipped with the Preferred Equipment Group (PEG) 3LT, indicating that it will build upon the features of the Chevy Silverado LT and LT Trail Boss lines, hence earlier reports indicating that the off-roader could be called the ZR2 Trail Boss.

To note, the Chevy Silverado LT’s PEG is 1LT, while the LT Trail Boss’ PEG is 2LT. The Chevy Silverado ZR2 will be based on the LT Trail Boss.

The Chevy Silverado LT Trail Boss is equipped with a variety of standard equipment, including (relevant RPO codes listed in parentheses):
  • Off-road suspension (Z71)
  • Hill Descent Control (JHD)
  • Skid plates (NZZ)
  • Heavy-duty air filer (K47)
  • Dual exhaust (N10)
  • Two-speed transfer case (NQH)
  • Two-inch suspension lift with monotube shocks (Z7X)
We spotted a prototype for the upcoming Chevy Silverado ZR2 plying public roads back in April, at which time we noticed the pickup wearing larger tires than the current Silverado Trail Boss model, with 33-inch rubber for the new model, as compared to 32-inch rubber for the current model. To be specific, the prototype model was equipped with Goodyear Wrangler Territory tires sized at 275/70R18, versus the 275/65R18 tires on the current Chevy Silverado Trail Boss.

Then in June, the Chevy Silverado ZR2 was spied again cruising public roads in prototype form, giving us another look at the off-roader. Later that month, General Motors released a teaser video showing the new Chevy Silverado ZR2 doing its thing in a mud puddle.

Slotting above the current Silverado Trail Boss as a more-capable off-roader trim level, the Chevy Silverado ZR2 is expected to feature upgraded suspension bits, including MultiMatic DSSV dampers similar to those found on the Chevy Colorado ZR2. It will also offer a revised front and rear fascia for greater ground clearance, a large front skid plate, and tow hooks. Under the hood, expect to find the naturally aspirated 6.2L V8 L87, currently rated at 420 horsepower and 460 pound-feet of torque in the 2021 Silverado 1500.

A launch will likely follow the introduction of the refreshed 2022 Chevy Silverado, set for unveiling next month.
