The Chevrolet Silverado 1500 IV Crew Cab Short Box, featuring the 4.3 EcoTec3 V6 engine paired with a four-wheel-drive automatic transmission, represents a notable chapter in Chevrolet’s long history of full-size pickup trucks. Produced from 2018 to 2021, this configuration held a significant position within the Silverado lineup, balancing capability, fuel efficiency, and affordability. It was part of the fourth-generation Silverado 1500 (Silverado 1500 IV), which introduced a more refined interior, lighter weight construction through the use of high-strength steel, and updated technology compared to previous generations. This specific variant was designed to appeal to buyers needing the roominess of a crew cab and the versatility of 4WD, without necessarily requiring the higher horsepower outputs of the larger V8 engine options.

Powertrain & Engine Architecture
The core of this Silverado variant is the 4.3L EcoTec3 V6 engine, internally designated as the LV3. This engine is a naturally aspirated, direct-injection V6 incorporating Active Fuel Management (cylinder deactivation) to enhance fuel economy. The direct injection system precisely delivers fuel directly into the combustion chamber, optimizing efficiency and power output. The engine employs an overhead valve (OHV) valvetrain, a design choice that contributes to its compact size and relatively straightforward maintenance. A 6-speed Hydra-Matic automatic transmission is coupled with the engine, providing smooth gear changes and appropriate ratios for both towing and everyday driving. While durable and reliable, this transmission doesn’t offer the efficiency gains of more contemporary 8 or 10-speed automatics.
Driving Characteristics
The 4.3L V6 engine produces 285 horsepower and 304 lb-ft of torque, combined with the automatic transmission, delivers adequate performance for most common truck tasks. Acceleration is reasonable, though not particularly quick, especially when contrasted with Silverado models equipped with the 5.3L or 6.2L V8 engines. The automatic transmission is calibrated for smooth operation and prioritizes fuel economy over aggressive shifting. Towing capacity is substantial, capable of handling up to 7,500 pounds when properly equipped. However, the smaller displacement engine requires more effort when towing heavier loads, potentially resulting in reduced fuel economy. The 4WD system enhances traction in adverse weather conditions and off-road environments.
Equipment & Trim Levels
The 4.3L V6 engine was typically offered on the base and mid-level trim packages of the Silverado 1500, such as the LS and LT. Standard features on these trims included air conditioning, a basic infotainment system with a touchscreen display, Bluetooth connectivity, and a rearview camera. Higher LT trims could be upgraded with features like leather upholstery, heated seats, a premium sound system, and advanced safety technologies. The Crew Cab configuration provides generous space for passengers in both the front and rear seats, making it a popular choice for families. Optional extras included a trailer package, upgraded wheels, and various appearance packages.
Chassis & Braking
The Silverado 1500 IV features a fully boxed frame constructed from high-strength steel, contributing to its rigidity and durability. The front suspension utilizes independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration balances ride comfort with a respectable payload capacity. Braking is provided by ventilated disc brakes on all four wheels, offering adequate stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety during emergency braking. Steering is rack-and-pinion with electric power assist, providing precise control and ease of maneuvering.
Market Reception & Comparison
The 4.3L V6-equipped Silverado 1500 generally received positive reviews as a capable and affordable full-size pickup truck. It presented a compelling alternative to the larger V8 engines, particularly for buyers prioritizing fuel economy and not needing maximum towing capacity. Compared to the 5.3L V8, the 4.3L offered slightly improved fuel economy but significantly less power and towing capability. The 4.3L also demonstrated greater reliability than some earlier versions of the 5.3L V8, with fewer reports of oil consumption issues. However, the 4.3L’s performance was sometimes criticized as being underwhelming, especially when compared to competing trucks from Ford and Ram.
Legacy
The 4.3L EcoTec3 V6 engine and the 6-speed Hydra-Matic transmission have proven to be relatively reliable powertrains. While not without minor issues, these components have generally performed well over time, and maintenance costs are typically reasonable. In the used car market, Silverado 1500 models equipped with this powertrain offer good value for buyers seeking a capable and affordable full-size pickup truck. The combination of a spacious crew cab, four-wheel drive, and a reasonably efficient engine makes this variant a practical choice for a wide range of needs. As with any used vehicle, a thorough inspection and review of the maintenance history are recommended before purchasing.
