Low Range Off-Road Body Lift Kits are available in either a 1'' or 2'' height. The biggest difference between Low Range's design and others is the 3" outer diameter solid UHMW spacers, while most other kits run a 2'' outer diameter. Increasing the O.D. to 3'' covers more surface area, giving the body more support. Body Lift Kits are drilled to the size of the stud adapter to eliminate play between the stud adapter and the spacer, ensuring that once the body is securely fastened, the body is fully supported.
