The 2012 Chevrolet Silverado 2500 comes standard with the 6.0L Vortec V8 engine (RPO code L96), producing 360 horsepower and 380 lb-ft of torque. This iron-block, aluminum-head engine features Active Fuel Management technology that deactivates four cylinders during light load conditions to improve fuel economy. The engine uses sequential fuel injection and variable valve timing for optimal performance and emissions. It’s paired with a 6L90E six-speed automatic transmission and is capable of towing up to 17,400 pounds when properly equipped. The 6.0L is known for its robust construction and strong low-end torque, making it ideal for heavy-duty work applications.

The 2012 Silverado 2500 shares most parts with the 2011-2014 model years, as these represent the same generation with minimal changes. Engine components from the 6.0L L96 are largely interchangeable across 2010-2014 HD trucks. Body panels, interior components, and suspension parts typically interchange within the 2011-2014 range. Some electrical components and modules may require programming when swapped between years. The transmission (6L90E) is compatible across 2011-2014 HD models. However, always verify part numbers and RPO codes, as GM made running changes throughout production. Cab configurations (regular, extended, crew) and bed lengths affect body panel compatibility.

The 6.0L L96 engine is generally reliable for heavy-duty applications, with most units reaching 200,000+ miles with proper maintenance. The iron block construction provides excellent durability under heavy loads and towing conditions. However, the Active Fuel Management system is a known weak point, with lifter failures occurring between 80,000-150,000 miles. Regular oil changes every 5,000 miles using quality oil and filters are crucial. Disabling AFM through tuning can prevent lifter issues. The engine responds well to maintenance and can provide decades of service when the AFM system is addressed proactively. Overall, it’s a solid workhorse engine with one significant design flaw that can be managed.
