About the Silverado L84 Engine 8-Speed

The L84 is GM’s newer 5.3L V8, introduced with the 2019 Silverado 1500. It uses Dynamic Fuel Management, which can deactivate cylinders in many combinations to improve fuel economy, along with direct injection and variable valve timing. It produces about 355 horsepower and 383 lb-ft of torque. The 8-speed automatic offers efficient gearing and smooth shifts.

The Silverado L84 engine 8-speed package is a direct replacement for compatible 2019-and-later trucks and a modern option for LT swaps.
