What Size Wrench is Needed to Install Hitch Ball # 63840


I’m Considering a Curt 45456/20k forged ball mount and a matching #63840 matching 20k ball. My question is what size socket will I need to tighten the nut?


Expert Reply:

When installing the hitch ball part # 63840 you need to use a 2 inch wrench on the wrench flats of the ball and a 1-7/8 inch wrench for the nut on the shank.
