Product Details

The latest GM 3500HD truck has raised the bar for what a heavy duty truck really is. It weighs nearly 7500 lbs., it’s available with a 397 horsepower, 765 lb-ft of torque diesel engine and can tow nearly 18,000 lbs! With all of the improvements made to the HD, the engineering team at Pro Comp has built their best suspension system possible to keep pace with these heavy haulers. Pro Comp’s HD suspension utilizes innovative features that enhance the strength and integrity of the suspension and allow it to be installed as a complete bolt on system. There are no holes to drill, no welding, no trimming of the front differential and no driveline modifications. This system can be installed in as little as 5.5 hours*.
