GM Authority Reports on Supercharged 6.2-Liter LT4 V8 Engine as a Possibility for Chevy Silverado ZRX

The upcoming Chevy Silverado ZRX may be the lucky recipient of Chevy's supercharged 6.2-L LT4 V8 engine, and the always-on-point staff of GM Authority offered up the details on their blog last week. It was reported here that according to TFL Truck, Chevy is hard at work on a version just for trucks of the supercharged 6.2L LT4 engine. It's set to make its way into the Chevy Silverado ZRX off-road pickup, our stealth competitor right here at Chuck Hutton Chevy of Memphis going up directly against the Ram Rebel TRX and Ford Raptor.

This high-performance engine that is already installed in the hefty pony in the form of the Chevy Camaro ZL1 cranks out 650 horsepower and 650 lb-ft of torque. GM Authority is one of those rare publications that waits very stealth-like in the shadows until things become official to activate the digital ink, and when they first wrote about the Silverado ZRX it was during September of 2019 after they had uncovered a trademark filing for the name in late summer.

 

This exciting off-road model will share many similarities with the Chevy Colorado ZR2, offering up MultiMatic DSSV Dampers, trustier suspension, front and rear electronic lockers, and modified bumper treatments for improved departure and approach angles. The ZRX is also going to feature the GM 10-Speed automatic transmission, but there are many hints that could show how GM will offer a more powerful engine option in the future as well. This truck-specific version of the 6.2-L LT4 V8 is slated to be used in other Chevy full-size SUVs, and perhaps even in a performance-focused Cadillac Escalade with a supercharged V8.

When it comes to the construction and finishing of a killer truck, the question then looms regarding where will it be shown at its best and highest performance. The announcement was also made last year about the brand-new off-road racing program for the Silverado ZRX, boasting a Silverado LT Trail Boss with MultiMatic DSSV dampers leading the way in the Best of the Desert off-road series. This will be the hands-on experiment that will provide the answers on how to develop suspension and other components in the more demanding areas of the motor sports arena.

In spy shots that appeared on the web earlier this year, the dampers seem to bear Rancho branding, the outfit who also supplies the pieces for the Z71 Off-Road package on the Silverado. It is also expected to see the new model with a major interior upgrade, seeing improvements to the infotainment system as well as a re-tweaked center stack. What the ZRX will actually bring to the table is the existence of an off-road-ready model a bit bigger than the ZR2, protected heavily by the best skid plates in the business and a major face-lift for an award-winning pickup poised to dominate any boulder-strewn and dirt-laden landscape!
