Specifications
The GM L83 engine is a 5.3-liter EcoTec3 V8 engine engineered to balance power, efficiency, and long-term durability. It features a lightweight aluminum block paired with advanced technologies such as Direct Injection, Variable Valve Timing (VVT), and Active Fuel Management (AFM), allowing the engine to deliver strong performance while maintaining respectable fuel economy. Introduced in 2014, the L83 is commonly found in a wide range of GM trucks and SUVs, where it has earned a reputation as a dependable and versatile powerplant.
On standard gasoline, the L83 produces around 355 horsepower and 383 lb-ft of torque, with even greater output available when running on E85 thanks to its flex-fuel capability. The engine’s 11.0:1 compression ratio, combined with a 3.78-inch bore and 3.62-inch stroke, contributes to a broad, usable torque curve ideal for towing, hauling, and everyday driving. Internally, the L83 is built for strength, utilizing a cast-iron crankshaft and forged powder-metal connecting rods to handle sustained loads and long service intervals. Overall, the GM L83 stands out as a modern small-block V8 that delivers proven reliability, solid performance, and efficiency for truck and SUV applications.
Engine Variants
L83
The L83 is the standard 5.3L Gen V EcoTec3 V8 introduced in 2014 for GM trucks and SUVs. It combines direct injection, VVT, and Active Fuel Management to deliver a strong balance of power, fuel efficiency, and durability, making it a dependable workhorse for towing and daily driving.
L8B
The L8B is the eAssist hybrid version of the 5.3L, pairing the L83 with a small electric motor and battery system. This setup provides modest power assistance, improved fuel economy, and smoother start-stop operation, primarily aimed at enhancing efficiency rather than outright performance.
L82
The L82 is an updated version of the L83 used mainly in 2019–2022 Chevy and GMC 1500 trucks. It retains AFM and the core EcoTec3 architecture while incorporating refinements for emissions compliance and drivability, continuing the L83’s proven performance and reliability.
L84
The L84 replaces the L83/L82 and introduces Dynamic Fuel Management (DFM), allowing the engine to deactivate any number of cylinders as needed. This results in smoother transitions, better real-world efficiency, and improved responsiveness, marking a more advanced evolution of GM’s 5.3L V8 platform.
