You are purchasing a Progressive DROP-IN Front Fork Lowering Kit for 1990 and newer Harley Sportsters except "Sport" models. This is Progressives' latest lowering kit design and transforms a time-consuming installation process into a quick and easy job. You can lower the front end of your bike 1 to 2 inches without completely disassembling the forks. Using basic hand tools, you will remove the top cap from the fork tubes and then change the springs. No mess with oil, seals, etc. Note: Some models will require removing the fork tubes to access the fork caps..
