To remove the stock supercharger pulley from your supercharger snout, an LFP Pulley Puller Tool is required. A generic "pulley puller" will not work, and could possibly cause damage to your stock pulley and/or supercharger shaft. The New LFP Tool is the Upgraded Version with New Steel Block, instead of Aluminum, to Totally Eliminate Any & All Bending during Removal or Installation of any supercharger pulley.
