Generally, you will need to buy the mounting plate separately as it does not come with the winch.  In the case of our second winch kit option of Champion Power Equipment-12003 ATV/UTV Winch Kit, 2000-lb. and our fourth winch kit option of ZEAK 3500 lb. Advanced 12V DC Electric Winch, the mounting plate comes with the winch. So, you can choose from these two options if you want to buy a winch with a mounting plate.
