what is the difference between suspension lift kits and body lift kits?

a suspension lift kit is a series of springs that work in tandem to lift the body of the car above its original height, body lifts. the engine, body and frame are all raised. On the other hand, body lift kits are used to suspend the body of the car above the frame. the overall functions of the two are however closely related. http://4wheelonline.com/ProCompSuspensionLiftKits.459
