The GMC Topkick line of medium-duty trucks comes specially upfitted by Monroe Truck Equipment, which takes transportation to the next level with luxury exterior finish, liberal use of stainless steel, and a high-end entertainment system. Topkick pickups now offer the Duramax 6600 V-8 turbo-diesel that delivers 605 pound feet of torque, and teamed with a smoother shifting Allison vocational transmission. Standard engine for the 2006 TopKick is the Vortec 8.1-liter gasoline V-8 that delivers 325 horsepower and 450 pound feet of torque. The front axle on 4x4 models is now rated at 8,000-pounds of load-carrying capacity, which is an additional 1,000 pounds versus the base axle of the previous years. You can view the GMC Topkick by Monroe Truck Equipment in the GM Fleet and Commercial display.
