Re: question about BIG GMC trucks

Its possible it had air brakes it has what looks like an air horn on the roof, look under the hood for an air compressor and air brake cans on the axles. Lots of late model axles out there with air brakes both front rear with better gears to swap into it. Converting it to single rear axle would be my choice. Some states require a CDL to drive anything with air brakes, some things to think about.
