Hot on the heels of fresh images of Chevrolet's next-generation Silverado 1500, our spy photographers have sent us the first-ever images of Chevy's 2014 Silverado 2500 Heavy Duty model.

The work-ready Silverado 2500HD will obviously share most of its styling with its light-duty cousin, but these images do reveal some key difference. The Silverado 2500 will make use of eight-lug wheels - versus six for the 1500 model - and will also ride slightly higher than Chevy's standard-issue Silverado. We can also see what appears to be a more substantial frame peeking out, along with a larger exhaust system.

Internally known as K2XCZ, the 2014 Silverado HD will make use of updated versions of Chevy's 6.0L and 6.2L gas engines. A 6.6L Duramax diesel will also be on offer.

GM is readying a new eight-speed automatic for its Silverado 1500, but that gearbox likely won't be available in HD models. Insiders say the eight-cog unit simply can't stand up to the torque demands of Heavy Duty trucks.

The 2014 Chevrolet Silverado 2500HD is expected to begin production October 2013.
