Advance Adapters is no longer affiliated with the Sidewinder Winch. The ownership and rights to the Sidewinder Winch has changed hands numerous times over the years and we currently do not know who holds the rights. As far as we can tell, these winches are no longer in production, nor are replacement parts are being produced. Below is a download of the owner’s manual and installation guide from when Advance Adapters was manufacturing and held rights to the winch. Other than this document we have no other information.
