The headline of the 2025 Chevy Silverado HD lineup is the addition of the Trail Boss.

We’re just coming off a moderate refresh of GM’s off-road HD trucks for 2024, so you would expect a range of fairly minor changes for the 2025 model year. For the most part, you’d be absolutely correct, though Chevrolet did decide to add a Trail Boss option to the Silverado HD on LT and LTZ trim. With that off-road model making its way to the heavy duty segment, the brand now has a complete range of Trail Boss trucks from the Colorado on up.

Sticking with the 2025 Chevy Silverado HD Trail Boss, what all do you get with the package? Apart from the decals on the bedsides, you get Z71 suspension and shocks, as well as blacked-out front and rear bumpers with red recovery hooks. The Trail Boss adds unique 20-inch gloss black wheels with chunky BFGoodrich All-Terrain T/A KO3 tires. Like the ZR2, you can still get the Silverado HD Trail Boss with either the standard 6.6-liter L8T gas V8 or the optional 6.6-liter L5P Duramax turbo-diesel V8. Either engine choice pairs up to an Allison-branded 10L1000 10-speed automatic transmission.

What about the rest of the 2025 Silverado HD lineup?

Across the board, powertrains remain the same for the 2025 model year. The 6.6-liter gasoline engine puts out 401 horsepower and 464 lb-ft of torque, while the Duramax diesel manages 470 horsepower and 975 lb-ft of torque.

Other changes to the 2025 lineup include the availability of front and rear park assist, which is standard on ZR2 and available on WT, Custom and LT trims. (It was already standard equipment on the High Country.) The top-end High Country trim now gets adaptive cruise control as standard, while a blackout package is available on the Custom trim. The HD Midnight Edition gets new 20-inch wheels.

2025 Chevy Silverado HD models will go on sale this summer, including the new Trail Boss package. Pricing isn’t available yet, but we don’t expect MSRPs to stray too much from their 2024 points. For reference, the base Silverado 2500HD WT starts at $49,895, while the fully-loaded High Country runs up to $73,995 with the gas V8. Depending on how you spec it — especially a 3500HD High Country dually with the Duramax engine — you can run the MSRP up well over $90,000 with all the bells and whistles.
