The GM L83 is the first-generation EcoTec3 5.3L V8 — the Gen V small-block engine that brought Dynamic Fuel Management and direct injection to the Silverado, Sierra, Tahoe, and Suburban, raising the bar for what a full-size truck and SUV V8 could achieve in terms of capability and efficiency simultaneously. This used GM L83 engine is a genuine OEM unit sourced from low-mileage donor vehicles and inspected before shipment. This is the factory 355-horsepower V8 that millions of GM truck and SUV buyers depend on.

The GM L83 Engine is a 5.3L V8 powerhouse designed for performance and reliability. As part of GM’s EcoTec3 family, the L83 engine delivers excellent fuel efficiency, direct injection, and smooth power output. Whether you’re searching for an L83 engine for sale or need an L83 crate engine, All American Motors Hub has the perfect solution.
Each L83 we provide is tested, inspected, and ready to install, ensuring long-term durability for your truck or SUV. It’s a trusted replacement option for GM vehicles, offering the balance of strength and efficiency that drivers demand.
L83 fitment requires matching your specific model year and application. The L83 was used in the 2014–2018 production run of the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade, with model year differences in AFM calibration and emissions setup. The 4WD application requires the correct output shaft configuration for the transfer case. Our VIN verification process confirms the exact L83 configuration for your specific vehicle before it ships.
The L83 is one of the most widely replaced engines in the current GM truck and SUV market — and buyers frequently compare the used engine, remanufactured engine, and OEM engine options for this application. A used GM L83 engine from a verified low-mileage donor is the most cost-effective path to factory-specification EcoTec3 performance. As a used OEM engine with original direct injection, AFM calibration, and 355 hp intact, it delivers what no remanufactured engine assembled from rebuilt cores can guarantee: factory GM specifications in an original assembly.
Every used GM L83 engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included, but we are happy to help you find a qualified GM truck mechanic. These are genuine General Motors OEM engines, and we stand behind every unit.
