CURT Trailer Balls
Tested for your safety.
A trailer ball may be one of the simplest components of your trailer hitch system, but it is also the direct connection between your vehicle and trailer. As such, a dependable trailer ball is vitally important.
Every CURT trailer ball is tested to meet U.S. VESC specifications for safety. Alongside our custom trailer hitches, multitude of ball mounts and heavy-duty towing products, our trailer balls are proven safe at our dedicated testing facility in Detroit, MI.
So, whether you’re towing a full-size travel trailer or a simple utility trailer, you can rest assured in the reliability of your CURT towing connection.
Three finishes available
Stainless steel
CURT stainless steel trailer balls are a premium option, offering superior rust resistance. They are available in various ball diameters and GTW capacities, and each one features fine threads for improved holding strength.
Chrome-plated
CURT chrome trailer balls are available in multiple diameters and GTW capacities, and like our stainless steel balls, they also feature fine threads. Their chrome finish over steel gives them solid resistance to rust and wear.
Raw steel
CURT trailer balls with a raw steel finish are intended for heavy-duty towing applications. They range in GTW capacity from 12,000 pounds to 30,000 pounds and feature a heat-treated construction for added wear resistance.

Patented design
A Switch Ball trailer ball uses a patented J-groove design to allow multiple ball sizes to be mounted on the same trailer ball shank.
Fast, easy installation
A Switch Ball trailer ball attaches easily with no tools, coins or pins required. The ball simply twists on, and you're ready to tow.
Secure towing
Once installed, the Switch Ball shank bears the trailer's tongue weight, taking stress off the ball and allowing for free movement.

Really nice hitch ball. Made to tow a lot of weight. I use it to pull my 14k dump trailer. So far, so good.

Happy with it. On a long trip with a 8,000 pound trailer and a brand new "and greased" Curt Chrome ball it I found it was galling and had ripped the top and sides up badly. I called Curt and they sent me a new one, but send the wrong size! So, I was stuck in Linn, MO, so I ordered a RAW one from Amazon. RAW ones are stronger with a much higher load rating and much less chance of galling. I drove 4,500 miles more with no problem and the ball still looks almost new. So from now on, I will always buy a RAW one.
