2018 Chevy Silverado Double Cab Overview
The 2018 Chevrolet Silverado double cab (called Crew Cab in Chevy's lineup) is the full-size pickup built for hauling people and gear. It sits on the GMT K2XX platform, which debuted for the 2014 model year and carried over with updates for 2018. The double cab configuration gives you four full doors and a slightly shorter bed than the regular cab or extended cab, making it a popular choice for families who also need a truck for work or towing.

Engine and Powertrain Options
The 2018 Silverado double cab comes standard with a 4.3-liter V6 producing 285 horsepower and 305 pound-feet of torque. Upgrades include a 5.3-liter V8 with 355 hp and 383 lb-ft, and a 6.2-liter V8 with 420 hp and 460 lb-ft. A 2.7-liter turbocharged four-cylinder is available on some trims, producing 310 hp and 348 lb-ft. All engines pair with a six-speed automatic transmission (except the 6.2L, which uses an eight-speed), and the truck is available in two-wheel drive or four-wheel drive.
Towing and Payload
Towing capacity depends on engine and configuration. The standard 4.3L V6 can tow up to 7,700 pounds when properly equipped. The 5.3L V8 maxes out around 9,800 pounds, and the 6.2L V8 reaches up to 11,500 pounds. Payload ratings range from roughly 1,500 to 2,200 pounds depending on bed length, cab size and drivetrain.
Double Cab vs. Other Cab Styles
The Silverado line offers three cab configurations: Regular Cab (two doors, longer bed), Double Cab (four doors, standard bed), and Crew Cab (four doors, short bed). The double cab provides a compromise — full rear passenger access and a larger cargo bed than the Crew Cab. The table below summarizes the key differences.
| Configuration | Doors | Bed Length (approx.) | Passenger Space |
|---|---|---|---|
| Regular Cab | 2 | 8 ft box | Front only |
| Double Cab | 4 | 6.5 ft box | Front and rear |
| Crew Cab | 4 | 5.5 ft box | Front and rear |
Trim Levels and Features
The 2018 Silverado double cab is offered in several trim levels: WT, Custom, LT, LTZ, and High Country. The WT serves as the base work truck with vinyl seating and steel wheels. The LT adds more convenience and technology features. The High Country tops the lineup with leather upholstery, a power liftgate, heated and ventilated seats, and a premium Bose audio system. The 2018 model year also introduced updated infotainment with Apple CarPlay and Android Auto integration across most trims.
Bed Length and Box Options
Double cab Silverados in 2018 were available with either a standard 6.5-foot bed or an 8-foot bed on certain configurations. The shorter bed makes accessing rear seats easier and improves maneuverability, while the long bed suits users who need maximum cargo capacity. Bed liners, tie-downs and integrated cargo management systems were available as options or on higher trims.
Reliability and Common Issues
The 2018 Silverado double cab is generally considered reliable, with the 5.3-liter V8 being a well-proven engine. Common issues reported by owners include minor electrical gremlins, occasional infotainment glitches, and wear on the rear suspension components with higher mileage. The 4.3L V6 and 5.3L V8 are the most popular engines for their balance of power and durability. Regular maintenance of the cooling system, transmission fluid and brake components helps sustain long-term reliability.
Should You Buy a 2018 Silverado Double Cab?
The 2018 Chevy Silverado double cab remains a strong used-truck option as of mid-2025, offering a capable mix of passenger room, towing muscle and modern tech for its age. If you prioritize interior space and need a full-size truck that can double as a daily driver and a workhorse, the double cab configuration is one of the most versatile choices in the lineup. Inspect the truck's service history, check for recall repairs, and test the transmission and four-wheel-drive system before buying.
