Upcoming Chevrolet Silverado ZRX May Get Supercharged 6.2L LT4 V8 Engine

The upcoming Chevrolet Silverado ZRX may receive the automaker’s supercharged 6.2L LT4 V8 engine.

According to TFL Truck, General Motors is working on a truck-specific version of its supercharged 6.2L LT4 V8 engine. This truck-focused performance engine will allegedly find its way into the Chevrolet Silverado ZRX off-road pickup, which will compete with products like the Ford Raptor and upcoming Ram Rebel TRX. The LT4 V8 is currently found in the Chevrolet Camaro ZL1, where it produces 650 horsepower and 650 pound-feet of torque.

GM Authority was first to report on the Chevrolet Silverado ZRX. We uncovered a trademark filing for the ‘Silverado ZRX’ name last summer and revealed exclusive details about the truck in a subsequent report published in September. The Silverado ZRX will follow a similar path to the Chevrolet Colorado ZR2, featuring more robust suspension, MultiMatic DSSV dampers, front and rear electronic lockers, and modified bumper treatments for improved departure and approach angles.

We also said previously the Silverado ZRX would feature GM’s naturally-aspirated 6.2L V8 L87 EcoTec3 engine and GM 10-speed automatic transmission. This would be representative of the route GM took for the Chevrolet Colorado ZR2, focusing on upgraded suspension and body updates and leaving the same powertrain as the regular version of the truck. This will still be the case, from what we know, but TFL Truck’s report may be a sign that GM will offer a more powerful engine option as well.

TFL Truck’s report also indicates the truck-specific version of the 6.2L LT4 V8 will be used in other GM products, such as its full-size SUVs. This lines up with rumors that GM is working on a performance-focused Cadillac Escalade with a supercharged V8 engine of some sort. It’s not clear when we can expect this supercharged Escalade model variant to arrive.

GM also announced its new off-road racing program for the Silverado ZRX last year. The new program will see off-road race team Hall Racing campaign a Chevrolet Silverado LT Trail Boss with MultiMatic DSSV dampers in the Best in the Desert off-road series. The truck will essentially serve as a real-world testbed for the Silverado ZRX, allowing Chevy to develop its suspension and other components in a demanding motorsports environment. Notably, Hall Racing’s truck has a naturally-aspirated 6.2L L87 V8 rather than an LT4.

      1. All the auto companies need to start bringing back the stick shift options in a special order it was dumb to do away with it completely just because the world was to lazy to learn to drive a stick or put the upgraded in their vehicle to get the power they needed for it i hate mudding in a automatic especially when i got to climb a big hill

  6. Chevrolet, GM specifically, has the capability to make a long lasting, bulletproof pickup capable of outperforming RAM, Ford, Toyota and Nissan.
    If you want to sell alot of trucks, make something that’ll last and hold its value. If you do, I’ll buy it.

  8. There is an LT4 Truck (T1xx) planned, but it’s been delayed by the pandemic.

  9. Here is hoping this will happen. While they are at it put the twin turbo 3.6 in the ZR2. But I am not going to hold my breath waiting for it. After all we are talking GM. They are becoming famous for over promising and under delivering.

  10. BUILD IT AN THEY WILL SPEND $

  11. While this is good news I fear this could be the first clue the Camaro is going away as we know it.

    GM appears to be looking for a home for the Corvette engines and the trucks would sell about the same volume and probably make more money.

    Just one word of caution, you asked for it and it appears they will build it. But it will not be cheap.

  12. I hope different exhaust outlets end up in the back as well to reflect the monster underneath the hood.

  13. Makes zero sense to not sell this as a GMC Sierra ATX. Ferd offers a premium experience (ie the platinum level not your xlt grade) , and the Sierra typically is the premium grade compared to the Silverado. More dinero = more money toward R&D = more badass vehicles = better stock prices.

    Force Chevy dealers to sell this.

  14. Get rid of the 4 doors! Only 2 door trucks in 2 wheel or 4 wheel drive become collector trucks.

    1. bow tie
      I say offer it equipped as you stated but on both the 2 door and 4 door. Also 2 wheel drive and 4 wheel drive.

  15. This truck can’t come soon enough! The Raptor has been our for 10 years now!! Chevy needs to go beyond the performance of Raptor and Ram and I’ll be first in line with my order!

  16. The automotive industry keeps bumping up the HP on cars and trucks, but yet our speed limits and traffic laws stay the same . Has this greedy industry turned our streets and roadways in dangerous race tracks for inexperienced and unprofessional drivers? I guess it has.

  17. Put it in a regular cab w/ standard bed and I’m in love.
    While they’re at it a manual transmission would be the icing on the cake.

  18. 6 speed,

  19. There is an old saying better late than never. But over ten years is pushing the limit. If they do bring this Truck out it had better be the top of its class. We can only hope because GM has developed a habit of being late and still being behind the curve.

  20. Maybe they can figure out their current motor and tranny issues (5 years by my count),before slapping another brand new expensive problem into the truck market.

  21. Ford isn’t taking the TRX lying down. I just read that they are dropping the GT500 engine into the Raptor.
