Pro Comp is proud to announce the release of their new 6” suspension system for the 2011 GM 2500 HD. This precision engineered system features all new CNC machined steering knuckles, super strong cross members constructed from ¼” thick steel, nitro charged shocks, integrated differential skid plate and heavy duty hardware. Every component of the Chevy 2500 HD Pro Comp suspension system has been tested and tuned to deliver superior strength, performance and a factory quality ride unlike any other lift system available. This system even maintains the factory turning radius. It is also 100% compatible with the factory Stabilitrak electronic stability control system. Installation can be done in as little as 3.5 hrs because there is no drilling, no welding, no cutting of the front differential and driveline modification required. Once installed, this system accommodates 35” tall tires and allows use of the factory 18” and 20” wheels.
