The four-wheel drive system pairs with Trail Boss-specific features, including an off-road suspension with a 2-inch lift and an auto-locking rear differential, giving you confidence on challenging terrain. The EcoTec3 5.3L V8 engine produces 355 horsepower and 383 lb-ft of torque, balancing power with efficiency at 14 city and 18 highway mpg.

The Trail Boss package goes beyond raw capability. You get performance red recovery hooks and hitch guidance for towing, plus an EZ Lift tailgate that makes loading and unloading simpler. The truck's black exterior is complemented by a high gloss black grille and 18-inch black painted aluminum wheels, creating a cohesive, purposeful appearance.

Inside the Custom cabin, you'll find practical comfort features designed for long days. The cloth seats include a 40/20/40 front split bench and rear 60/40 folding bench for flexible seating and cargo arrangements. Dual front and side impact airbags, along with an overhead airbag system, prioritize safety. The tilt steering wheel and manual adjustability ensure you find your ideal driving position.

Technology keeps you connected and informed. Apple CarPlay and Android Auto integration allows seamless smartphone control, while SiriusXM Radio and the Chevrolet Infotainment 3 System with a 3.5-inch display keep entertainment and information at your fingertips. Bluetooth® connectivity, remote keyless entry, and a remote vehicle starter system add modern convenience to your daily routine.

Practical touches round out the package. Heated door mirrors assist in poor weather, fully automatic headlights and delay-off features enhance safety, and dual exhaust with polished outlets add visual appeal. The power windows, including express down functions, and variably intermittent wipers respond to changing conditions. An auxiliary external transmission oil cooler supports consistent performance under load.

This Silverado 1500 Custom Trail Boss is a clean, one-owner vehicle ready to handle whatever comes next. Whether you need a reliable work truck, a weekend adventure partner, or both, this truck delivers the features and capability to meet your needs. We invite you to experience it in person and take a test drive.
