As of last week, Chevrolet is restricting the ordering of its 4.3L V6 engine on some Silverado trim levels.
GM-Trucks.com has learned that as of March 22nd, the 4.3L V6 engine in the 2021 Chevrolet Silverado is being highly restricted to only Base model and Custom Trail Boss trim level pickups.
Prior to the 22nd, the LV3 4.3L V6 with active fuel management was an option to order on base, Custom, and Custom Trail Boss trim level Silverado. Now, Custom trim levels are being shut out of the engine entirely.
Going forward, Silverado Custom pickups will come with the 2.7L I4 turbocharged engine standard. Custom Trail Boss models will still have the option of the 4.3L V6.
This comes after GM announced that 5.3L engines with active fuel management and dynamic fuel management would no longer be produced during the 2021 model year. The global semiconductor chip shortage is to blame and the company will re-use older/cheaper electronic control modules that are not AFM/DFM compatible to be able to continue Silverado production.
GM-Trucks.com has already reported on Chevrolet’s decision to stop production of the 4.3L engine for 2022.
