CURT 40006 Chrome Trailer Ball, 2-5/16 Inch Diameter, 10,000 Lb Capacity

Powerful CURT 40006 Chrome Trailer Ball

The CURT 40006 chrome trailer ball is designed for heavy-duty towing, blending brute strength with weather-ready chrome finishing. Crafted from hot-forged steel, this ball is built to endure demanding road conditions and provide steady performance mile after mile. The bright chrome surface not only looks sharp but also helps resist corrosion in wet and dirty environments.

At the heart of this trailer ball is a precise fit: a 2-5/16 inch diameter ball with a 1-1/4 inch shank and a 2-5/8 inch shank length. These dimensions align with most 2-5/16 inch couplers, enabling quick, confident hookups with compatible ball mounts. The combination of material strength and meticulous machining translates to smoother engagements and a reliable connection, even when towing sizable loads.

Beyond raw strength, CURT emphasizes secure installation. The set includes a zinc-plated hex nut and a helical lock washer, and the ball features fine threads that improve grip on the hitch, supporting a solid fit once tightened. The finish is designed to withstand wet weather, road grime, and the usual wear of frequent towing, helping the hardware stay visually clean while performing consistently.

Versatile use cases you might encounter

Whether you’re hauling a dump trailer, toy hauler, farm trailer, chopper box, or a dual-axle utility trailer, this 2-5/16 inch trailer ball is built to work with class 5 hitch components. It also serves as a dependable option for deluxe RVs and even certain small yachts when paired with the appropriate mount and safety hardware. Real-world versatility is a key benefit here, offering a single, capable solution for multiple setups.
