Introduction
The Silverado 1500 IV, launched in 2016, represented a significant update to Chevrolet’s best-selling full-size pickup. The 2018-2021 model years saw incremental improvements to the platform. The Regular Cab Long Box configuration, paired with the 4.3L EcoTec3 V6, was positioned as the most affordable entry point into the Silverado 1500 range. It catered to buyers who needed the functionality of a full-size truck but didn’t require the higher performance or luxury features of the larger engines or more upscale trim levels. This variant was primarily sold in North America, where full-size pickups are a dominant force in the automotive market.
Powertrain & Engine Architecture
The heart of this Silverado variant is the 4.3L EcoTec3 V6 engine, designated as the LV3. This engine is a naturally aspirated, 90-degree V6 featuring aluminum cylinder heads and a cast iron block. It utilizes direct fuel injection (DFI) and variable valve timing (VVT) to optimize fuel efficiency and power delivery. The EcoTec3 family of engines is known for its cylinder deactivation technology, which allows the engine to operate on fewer cylinders during light-load conditions, further enhancing fuel economy. The six-speed Hydra-Matic automatic transmission, a GM staple, was the sole transmission option for this configuration. This transmission is known for its smooth shifting and durability, though it lacks the eight or ten-speed automatics found in some competitor models. The transmission’s gear ratios are tuned for a balance of towing capability and fuel efficiency, prioritizing usability over outright acceleration.
Driving Characteristics
The 4.3L V6, producing 285 horsepower and 305 lb-ft of torque, provides adequate power for everyday driving and light-duty tasks. However, it’s noticeably less powerful than the available 5.3L and 6.2L V8 engines. Acceleration is modest, and passing maneuvers require planning, especially when towing or carrying a heavy load. The automatic transmission shifts smoothly, but can sometimes feel hesitant when downshifting. Compared to the manual transmission options available on other Silverado trims, the automatic prioritizes convenience over driver engagement. The long box configuration provides ample cargo space, but it also contributes to a longer wheelbase, which can make maneuvering in tight spaces more challenging.
Equipment & Trim Levels
The 4.3L V6 Regular Cab Long Box Silverado typically came standard with basic features such as air conditioning, a rearview camera, and a basic infotainment system with a 7-inch touchscreen. Higher trim levels, such as the LT and RST, added features like upgraded infotainment systems with Apple CarPlay and Android Auto compatibility, power windows and locks, keyless entry, and chrome exterior accents. Optional extras included a trailer package, upgraded audio systems, and various convenience features. Interior upholstery was typically vinyl or cloth, with higher trims offering leather options. The dashboard layout was functional and straightforward, prioritizing usability over luxury.
Chassis & Braking
The Silverado 1500 IV utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension features independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration is designed to handle heavy loads and provide a comfortable ride. The braking system consists of ventilated disc brakes on all four wheels, with larger rotors on the rear axle. Anti-lock brakes (ABS) are standard. The rear leaf spring suspension, while capable, can result in a somewhat less refined ride quality compared to trucks with independent rear suspension.
Market Reception & Comparison
Critics generally viewed the 4.3L V6 Silverado as a competent but unremarkable offering. It was praised for its affordability and fuel efficiency, but criticized for its lack of power compared to the V8 options. Fuel economy figures were competitive within the full-size pickup segment, averaging around 16 mpg city and 21 mpg highway. Compared to the 5.3L V8, the 4.3L offered significantly lower towing capacity and acceleration. However, it was more fuel-efficient and less expensive to purchase. The 4.3L also offered a more affordable alternative to competitors like the Ford F-150 with its base V6 engine.
Legacy
The 4.3L EcoTec3 V6-powered Silverado 1500 has proven to be a relatively reliable powertrain. While not known for exceptional performance, the engine and transmission have demonstrated good durability with proper maintenance. On the used car market, these models represent a value-oriented option for buyers seeking a capable full-size truck at a lower price point. Common maintenance items include regular oil changes, transmission fluid flushes, and inspections of the cylinder deactivation system. Overall, the 4.3L Silverado remains a practical and affordable choice for those needing a workhorse pickup truck.
