Hummer design is iconic. Just as the legendary H1 and H2 has heightened the freedom, excitement and driving experience of Hummer ownership, the H3T is an all-new mid-sized, four-door pickup truck based on the popular H3 SUV, but features a five-passenger crew cab and a separate five-foot-long bed that is capable of carrying two dirt bikes, a snowmobile or ATV and full sheets of plywood. The H3T is powered by a 242-hp 3.7-liter inline five-cylinder engine bolted to a standard 5-speed manual or optional 4-speed automatic transmission. An available 300-hp 5.3-liter V8 with 4-speed automatic transmission provides power for increased towing capacity and quicker acceleration in the Alpha version. . More power, sound and style are just some of the added benefits of upgrading to a Billy Boat Performance Exhaust system. You see it, you hear it and you feel it. Billy Boat Performance Exhaust, the leader in aftermarket performance exhaust systems, offers much more than an aircraft quality, T304 stainless steel exhaust system. We deliver increased, dyno-tested horsepower, as well as incredible exhaust sound and distinguished style for the H3T Hummer, a vehicle that lives up to its image in every way.
