In a medium saucepan, bring 2 cups water to a boil. Add sugar and stir constantly until completely dissolved. Remove from heat and set aside to allow to cool thoroughly (about 15 minutes).
Pour sugar water, additional 2 cups water, Everclear, cherry syrup, and cherry vodka into a large pitcher. Stir to combine.
Divide sour cherry balls among mason jars (we used 16 oz mason jars). Then, pour the liquor mixture in on top of them, filling each jar to the top. Close the jars and place in the refrigerator for 1 week.
After a week, pour the moonshine from each jar through a strainer into a pitcher to remove any remains of the sour cherry candies. Then, pour moonshine back into the mason jars and shake to ensure flavors are well blended. Store jars in refrigerator until ready to enjoy.
