Ride height adjustable shocks are not intended to ALTER your ride height, They are adjustable to work with different height suspension setups. The truck is WAY too heavy to use a shock absorber as a device to create lift. A shock simply doesn't have the strength to bear the load of your truck on it's own. Coil-over shocks, on the other hand, CAN give you a minimal amount of lift because part of the assembly is a coil spring. It works on some level as a helper spring. They work well on vehicles where there is spring wear and weakening of the springs, but not as a replacement of the springs. The very nature of the name of the part in question "Shock Absorber" is descriptive enough to tell you what it's function is: to absorb impacts of uneven surfaces that you encounter while driving... to Absorb Shock... It is not a lift kit.
