Built for durability and predictable performance, the CURT 40020 tow ball blends hot-forged steel construction with a nickel-chrome finish and fine-threaded shank to give you a reliable connection between vehicle and trailer.

How does this hitch ball fit my trailer and tow vehicle?

The 2" ball diameter is the standard size for most utility, boat, camper and ATV trailers. The 1" diameter shank fits common ball mounts and drops, and the 3" shank length provides enough thread engagement for a secure installation with the supplied nut and washer. Always match the ball diameter to your trailer coupler and never exceed the lowest rated component in your towing setup.

• Ball diameter: 2" to match standard 2" couplers
• Shank: 1" diameter, 3" length for deep thread engagement
• Hardware included: zinc-plated hex nut and helical lock washer
• Compatibility: common with class 3 and class 4 ball mounts

What towing capacity and strength can I expect?

This CURT model is rated for a gross trailer weight of 6,000 lb, suitable for many medium-duty towing tasks like boats, utility trailers, campers, and smaller RV setups. The ball is hot-forged from steel to deliver strength under load, and the fine threads on the shank improve clamping force when torqued to specification. Remember to confirm other components’ ratings — hitch, vehicle, and trailer — as the overall safe towing limit is determined by the lowest-rated part.

• Gross trailer weight capacity: 6,000 lb
• Construction: hot-forged steel for consistent strength
• Threading: fine-thread shank increases holding strength
• Installation torque: follow specified torque for secure fit

How does the finish and hardware protect the hitch ball?

The CURT 40020 is finished with nickel-chrome plating that resists corrosion, scratches and grime better than bare steel, extending usable service life. It ships with a zinc-plated hex nut and helical lock washer to help maintain clamp force and resist loosening under vibration. Routine inspection and cleaning will further prevent rust and keep the mating surfaces operating smoothly.

• Finish: nickel-chrome plating for corrosion resistance
• Included fasteners: zinc-plated hex nut and helical lock washer
• Maintenance: clean and inspect for wear or corrosion periodically
