2013 Chevrolet Silverado 2500: What's New, Specs & Features
Last updated August 4, 2026
The 2013 Chevrolet Silverado 2500HD is a light-update year, led by a factory bi-fuel gasoline/CNG setup on some Extended Cab gas trucks. Gas V8 models also gain grade braking in normal driving mode, while the rest of the truck largely carries over from 2012.
About the 2013 Chevrolet Silverado 2500
2011-2014 Silverado HD generation, third model year, two years before the 2015 heavy-duty redesign.
The Silverado 2500HD is Chevrolet’s heavy-duty pickup for buyers who tow large trailers, carry heavy payloads, or need durable jobsite hardware. Chevrolet markets it around big towing capability, multiple cab and bed choices, gas or diesel V8 power, and built-in trailer control aids. A key difference versus many rivals of the time is its independent front suspension, which helps give the truck more settled road manners and more precise steering without giving up serious work capability.
The Work Truck remains the no-nonsense version, with vinyl seating, steel wheels, trailer-sway control, and heavy-duty suspension. LT adds everyday comforts such as cloth seating, power accessories, heated mirrors, and alloy wheels, while LTZ brings leather front seats, dual-zone climate control, Bluetooth, remote start, and Bose audio.

How is the 2013 Silverado 2500HD different from the 2012 model?
The 2013 model adds a gasoline/CNG bi-fuel setup to some Extended Cab gas trucks and gives gas V8 versions normal-mode grade braking through the six-speed automatic. The styling, chassis, trim ladder, and main towing hardware otherwise carry over.
Was the 2013 Chevrolet Silverado 2500HD redesigned?
No. The 2013 Silverado 2500HD was not redesigned or refreshed; it received only small powertrain-related updates within the existing 2011–2014 generation.
What does grade braking do on the 2013 Silverado 2500HD?
Grade braking helps a gas V8 truck hold its speed on a downhill stretch by using the six-speed automatic transmission. For 2013, this function operates in normal driving mode.
Did the 2013 Silverado 2500HD get new styling or cabin technology?
No. The 2013 model received no significant styling update or meaningful lineup-wide cabin technology change compared with 2012.
