The new Chevy Silverado & GMC Sierra 2500 HD truck has raised the bar for what a heavy duty truck really is. It weighs nearly 10,000 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 2500 HD pickup truck, the engineering team at Pro Comp set out to build the best suspension system possible to keep pace with the new Silverado & Sierra trucks. The result is a 6 inch suspension system that will set the standard for what a suspension lift system should be.

Our engineers also made the new suspension very friendly for the installer. It utilizes innovative features that enhance the strength and integrity of the suspension and allow it to be installed as a complete bolt on system. With no holes to drill, no welding, no trimming of the front differential, no driveline modifications, this system can be installed in as little as 3� hours.
