2-1/8" Long x 1" diameter shank featuring a ball with a 1" high rise above the platform. Fine threads provide superior strength, and the nickel chrome finish offers corrosion protection.

Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to be taking a look at part number C40033. This is the Curt Two-inch Hitch Ball. It's going to have the one-inch rise, and it's rated at 6,000 pounds. The high-rise design is going to let you easily match the ball to your trailer height. The trailer hitch ball is going to sit an extra inch above the ball mount platform, so the rise is this portion right here. It's going to offer fine threads. These are going to provide exceptionally tight, strong grip once installed.
This is a steel construction with a nickel chrome finish, so it's designed to resist rust and corrosion. The lock washer and the nut are both included. The ball diameter is going to measure 2 inches. Here at the shank, it's going to give us a shank length measuring from the bottom of the platform to the end of the threaded portion of 2 and 1/8 of an inch. It's going to give us a shank diameter of one inch. The ball shank diameter, this is just something to keep in mind, that should be within 1/16th of an inch of the ball mount hole diameter on the ball mount.
Keep that in mind when choosing a ball mount or when choosing a hitch ball. The rise, we'll take a measurement of that. That's going to measure right at one inch. Again, the hitch ball is rated with a capacity of 6,000 pounds. Very easy installation. All you have to do is place the threaded portion down through the ball hole, and that would be on the ball mount.
Place on the lap washer followed by the nut, then you need to get everything tightened down and torqued to specifications. It's going to come with a nice little instructional tag that's going to be installed on the shank. You want to be sure to remove that. That's going to have the proper torque rating on there, and some other information that you need to go off of. That's going to do it for our review of part number C40033. This is the Curt Two-inch Hitch Ball.

Rust can be troublesome no matter when it occurs. You will want to grease the ball every now and again to help protect. A multi purpose grease like part # L11316 will do the trick.

We purposely dull the finish so we can photograph the ball. If we didnt do so, the glare from the cameras flash would make it hard to make out any detail on the trailer ball.

In follow up to my review I would like to recommend that The company start making these out of stainless steel. I just bought a new 1 rise hitch ball and it is the third one I have bought over the last three years because they rust up so badly. I have tried the Reese hitch ball grease and plastic covers however by the end of winter when I am ready to get the boat and trailer out for the summer the hitch ball is so rusted I cant even wire brush it off. I really like these Curt hitch balls for their 1 rise which levels my trailer nicely but it is a pain to replace them every year. This last one got so rusted I had to use a reciprocating saw to get it off the hitch. In follow up to my review I would like to recommend that The company start making these out of stainless steel.

So far, Ive used this for many trips covering several thousand miles. It continues to perform its intended purpose. After a year of use much more of the chrome plating has wornpeeled off. The issue is not how this hitch ball appears, its that the pieces of chrome that are wornpeeled off accelerate the wear on the ball AND the inside of my trailer ball hitch receiver.
