The robust chassis and heavy-duty suspension are designed to support substantial payloads with consistent composure, while GMC’s independent front suspension architecture contributes to a smoother ride and confident steering feedback compared to traditional solid-axle setups. Available off-road-focused hardware, including skid plates and the X31 Off-Road Package with twin-tube Rancho shocks, delivers extra assurance on unpaved approaches and farm lanes. Braking confidence comes through with large, fade-resistant components tuned for loaded conditions, and the available diesel exhaust brake (with Duramax®) helps manage descents by leveraging engine braking to reduce pedal work and heat.

Powertrain - GMC Dealership near Jacksonville, IL

For those who pull heavy, the available Duramax® 6.6L Turbo-Diesel V8, also matched to the Allison 10-speed, adds massive low-end torque and an available exhaust brake for downhill composure with a loaded trailer. Traction Select System with Tow/Haul mode on equipped trims optimizes throttle, shift mapping, and stability calibrations for the job at hand, while trailering technologies—like up to 13 or even up to 14 available camera views on select models, including Transparent Trailer View—help you keep tabs on hitch, cargo, and surroundings.

Pair that with an efficient 10-speed spread and gear-holding logic, and you get confident acceleration onto highways, stable passing, and calm, predictable control when the load pushes back. This is the muscle and intelligence you expect from a GMC HD.
