The Cognito Standard 6" Lift Package is preconfigured with all of the standard components that we recommend and have preselected to properly lift your 4WD GM 2500 truck.

All Cognito Standard Lift Packages consist of individual component boxes that together, include the necessary components to achieve a complete front/rear lift. Cognito lift packages are compatible with specific vehicles based on precise "year, make, model and submodel" selections.

In some instances, there are subtle changes in manufacturer chassis, suspension, steering, brake and drive-train configurations (between model production years and half-years) that will dictate specific component configuration requirements.

Cognito Standard Lift Packages are pre-configured to achieve "level" vehicle rake (front-to-rear ride height), then we provide you with component options that allow you to change the rake angle, in addition to upgrade options such as: upper control arms, shocks, traction bars, compression struts and other components, that are popular choices among our professional builders.
