2011-2014 Chevrolet Silverado 3500 HD II (GMT900 facelift ) Crew Cab Long Box 6.0 V8 (360 Hp) DRW Automatic

The Chevrolet Silverado 3500 HD II, specifically the Crew Cab Long Box configuration with the 6.0-liter V8 engine and automatic transmission, represents a significant iteration of Chevrolet’s heavy-duty pickup truck lineage. Produced from 2011 to 2014 as part of the GMT900 generation (following a facelift), this variant was aimed at buyers needing substantial towing and hauling capacity combined with a degree of passenger comfort. It occupied a middle ground within the 3500 HD lineup, offering a balance between the more affordable work-truck trims and the fully-loaded luxury versions.

Technical Specifications

INTRODUCTION

The 2011-2014 Chevrolet Silverado 3500 HD II Crew Cab Long Box, powered by the 6.0-liter Vortec L96 V8 and paired with a six-speed Hydra-Matic automatic transmission, was a workhorse designed for demanding tasks. Built on the GMT900 platform, this generation represented a significant upgrade in capability and refinement over its predecessor. The “II” designation denotes the facelifted version, introduced in 2011, featuring revised styling and improved interior materials. The Crew Cab configuration offered spacious seating for five passengers, while the Long Box provided ample cargo space. This particular combination aimed to appeal to owners who frequently towed heavy loads – boats, trailers, or equipment – while still requiring a comfortable and practical daily driver.

Powertrain & Engine Architecture

At the heart of this Silverado 3500 HD II lies the Vortec L96 6.0-liter V8 engine. This engine is a member of Chevrolet’s well-regarded Vortec family, known for its robust construction and reliable performance. The L96 features a cast iron block and aluminum cylinder heads, utilizing a 9.6:1 compression ratio and a multi-port fuel injection system. The overhead valve (OHV) valvetrain, coupled with variable valve timing (VVT), helps optimize power delivery and fuel efficiency. The engine produces 360 horsepower at 5400 rpm and 515 lb-ft of torque at 4200 rpm. The Hydra-Matic 6L80E six-speed automatic transmission was specifically chosen for its durability and ability to handle the engine’s substantial torque output. This transmission features electronically controlled shifting and overdrive for improved highway fuel economy. The transmission’s gear ratios are tuned for both towing and everyday driving, providing a balance between acceleration and fuel efficiency.

Driving Characteristics

The Silverado 3500 HD II with the 6.0L V8 and automatic transmission delivers a driving experience focused on capability rather than outright sportiness. The automatic transmission provides smooth and predictable shifts, making it easy to operate in various driving conditions. While not as quick as versions equipped with the optional Duramax diesel engine, the 6.0L V8 offers ample power for most towing and hauling needs. The 6L80E transmission’s gear ratios are well-suited for maintaining momentum when towing uphill, and the overdrive gear helps keep engine speeds low on the highway. Compared to manual transmission versions, the automatic offers greater convenience, especially in stop-and-go traffic. However, some drivers may prefer the more direct control offered by a manual gearbox. The substantial weight of the truck is noticeable, but the torsion bar front suspension and leaf spring rear suspension provide a reasonably comfortable ride, even when unladen.

Equipment & Trim Levels

The Crew Cab Long Box configuration typically came standard with a good level of equipment. Standard features included air conditioning, power windows and locks, a tilt steering wheel, and a basic audio system. The interior upholstery was typically cloth, although leather options were available. The dashboard layout was functional and straightforward, prioritizing ease of use. Optional extras included a premium audio system, navigation, heated seats, a power sunroof, and various towing packages. The Silverado 3500 HD II offered a range of trim levels, from the base WT (Work Truck) to the more luxurious LT and LTX models. The 6.0L V8/automatic combination was available across most trim levels, allowing buyers to customize their truck to their specific needs and budget.

Chassis & Braking

The Silverado 3500 HD II features a robust chassis designed to withstand heavy loads. The front suspension utilizes an independent torsion bar setup with double wishbones, providing a comfortable ride and good handling. The rear suspension employs a traditional leaf spring design, offering excellent load-carrying capacity. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The truck’s steering system utilizes a cone worm with recirculation balls, offering a solid and predictable feel. The dual rear wheel (DRW) configuration, common with this engine and trim, further enhances stability and load-carrying capacity.

Market Reception & Comparison

The 2011-2014 Chevrolet Silverado 3500 HD II with the 6.0L V8 and automatic transmission was generally well-received by critics and consumers. It was praised for its strong towing capacity, comfortable ride, and spacious interior. However, its fuel economy was a common criticism, as expected for a heavy-duty truck. Compared to the diesel-powered Silverado 3500 HD models, the 6.0L V8 offered a lower initial cost but less torque and lower fuel efficiency. Compared to the Ford Super Duty and Ram Heavy Duty trucks of the same era, the Silverado 3500 HD II was considered competitive in terms of capability and features. The 6.0L V8 was often seen as a good option for buyers who didn’t require the extreme towing capacity of a diesel engine but still needed a powerful and reliable truck.

Legacy

The Vortec L96 6.0L V8 engine, paired with the 6L80E automatic transmission, has proven to be a durable and reliable powertrain combination. These trucks are still commonly found on the used car market today, and well-maintained examples can provide many years of service. While not as fuel-efficient as newer trucks with advanced engine technologies, the Silverado 3500 HD II remains a popular choice for buyers seeking a capable and affordable heavy-duty pickup. The engine’s relatively simple design makes it easier and less expensive to maintain compared to more complex diesel engines. The GMT900 platform, while superseded by newer generations, remains a solid and dependable foundation for a work truck.
