2025 Chevrolet Silverado 3500 HD Trim Levels
The 2025 Silverado 3500 HD is built for those who need serious power and durability in a heavy-duty truck. With gas and diesel V8 engine options, it easily handles everything from heavy loads on the job site to long-distance towing. While it’s engineered for toughness, the interior balances function with comfort, incorporating modern features that make it feel more like a premium vehicle than a work truck. This combination of strength and refinement makes the Silverado 3500 HD a top choice for buyers at dealerships like the First Mesa Chevrolet dealer looking for a reliable and capable truck.
2025 Chevrolet Silverado 3500 HD Trim Levels
The 2025 Silverado 3500 HD is offered in six trims: Work Truck, Custom, LT, LTZ, ZR2, and High Country. The standard powertrain is a 6.6-liter V8, delivering 401 horsepower and 464 lb-ft of torque. For those needing even more muscle, the available Duramax diesel V8 generates 470 horsepower and 975 lb-ft of torque. Both engines are mated to an Allison 10-speed automatic gearbox. According to the First Mesa Chevrolet dealership, buyers can select between rear-wheel drive or four-wheel drive, as well as single or dual rear-wheel setups, depending on their needs.

The Work Truck (WT) is the entry-level trim, designed for utility and durability. It features vinyl seating, manually adjustable front seats, and a split 40/20/40 front bench. Double Cabs and Crew Cabs get a 60/40-split rear bench, air conditioning, and power windows and locks. Standard tech features include a 7-inch infotainment touchscreen, Apple CarPlay and Android Auto, an audio system with two or six speakers (depending on cab size), Bluetooth, Wi-Fi connectivity, and two USB ports. A 3.5-inch driver display provides important vehicle information.
Safety features include automatic emergency braking with forward collision warning, lane departure warning, auto high beams, a rear-seat alert, a backup camera, and Chevy’s Teen Driver system.

The Custom trim builds on the WT, adding keyless entry, cloth upholstery, power-adjustable side mirrors, cruise control, and satellite radio. Buyers can opt for the available Blackout package, which includes black bowtie emblems, black badging, and 20-inch high-gloss black-painted wheels, giving the truck a bold, aggressive look.

The LT trim comes with 17-inch alloy wheels, a power-locking tailgate, and proximity keyless entry. Inside, there’s a 12.3-inch digital gauge cluster, an integrated trailer brake controller, and a larger 13.4-inch touchscreen. The infotainment system adds voice recognition and Google Apps integration.

The LTZ model adds premium upgrades for a more refined experience. It comes with 18-inch alloy wheels wrapped in all-terrain tires, LED fog lights, and rain-sensing wipers. Inside, it features leather upholstery, heated and power-adjustable front seats, and a heated steering wheel. Additional comforts include dual-zone climate control, an auto-dimming rearview mirror, and extra USB ports. It also includes two household-style power outlets for added convenience.

The ZR2 trim builds on the LTZ for serious off-road capability, incorporating rugged performance features. It comes with a 1.5-inch factory lift, 35-inch all-terrain tires, an electronic rear locking differential, upgraded shocks, skid plates, tow hooks, and hill descent control.
The cabin features ventilated front bucket seats, heated rear outboard seats, and a center console. Other standard features include LED bed lighting, a power-sliding rear window, a bed-view camera, a seven-speaker Bose audio system, wireless charging, and additional USB ports. Safety enhancements include a surround-view camera system, rear parking sensors, and rear cross-traffic alert.

The High Country trim represents the pinnacle of comfort and convenience in the Silverado 3500 HD lineup. It swaps out the ZR2’s off-road components for more premium features, including 20-inch alloy wheels, front and rear parking sensors, carpeted floor mats, and adaptive cruise control. These enhancements make long highway drives more comfortable while maintaining the truck’s signature strength and versatility.
