A body lift kit is a 1, 2, or 3 inch lift kit that only lifts the body from the frame. These inexpensive kits mainly consist of blocks or spacers. Body lifts do not increase ground clearance; however, it will normally allow for slightly taller tires because it will increase the height of the wheel wells. Depending on the model of vehicle and the height of the body lift kit, you may need to invest in additional parts to raise the bumpers, extend the gearshift through the floorboard of the vehicle and making other modifications to accommodate the body lift. Although a body lift causes a vehicle to sit higher, it does not alter or improve suspension, or increase travel.
