Review of Curt Balls C40005

Today we're going to be taking a look at the Curt 2 5/16 inch hitch ball. This hitch ball provides a connection point for your trailer's coupler. It's a steel construction with a durable, corrosion-resistant nickel chrome finish. It's going to feature fine threads that provide tight, strong grip and it's going to have the wrench flats on it. Right here it's got the flat sides on the flat form. That allows for an easier installation.

It's also going to come with your split lock washer and the mounting nut. In the manufacture specifications those are going to be on a tag that comes on the ball. That's where you're going to find the torque rating for this particular hitch ball. Again the diameter is 2 5/16 of an inch. It's going to have a weight capacity of 7,500 lbs. shank diameter is going to measure 1 inch.

Shank length is 2 1/8 of an inch and this is designed to fit on a ball mount that has a draw bar or a platform thickness of at least 3/8 of an inch. You place this through the ball hole. On the underside you'd put the split lock washer and then you would place on the nut. Get that all the way tightened down and torqued to the specifications listed by the manufacturer. That's going to do it for today's look at the Curt 2 5/16 inch hitch ball.
