How much weight can this CURT hitch ball tow?

• 6,000 lb gross trailer weight rating
• Works with most standard-duty and many heavy-duty trailers
• Follow vehicle and hitch capacity limits when calculating safe towing weight

Will this ball fit my 2" coupler and hitch mount?

Yes—this model has a 2" diameter ball to match standard 2" couplers. The shank measures 1" in diameter and 2-1/8" in length so it fits securely through most ball-mount holes when used with the appropriate hardware.

• 2.00" ball diameter for standard 2" couplers
• 1.00" shank diameter and 2-1/8" length for common ball mounts
• Includes hex nut and helical lock washer for secure mounting

How does the stainless-steel finish help in real-world use?

The stainless steel construction provides strong resistance to rust and surface wear from road elements like salt, mud, and rain. That corrosion resistance helps maintain appearance and structural integrity over time, reducing the need for frequent replacement.

• Stainless-steel body resists corrosion and pitting
• Durable surface finish reduces visible scratches and staining
• Low maintenance compared with plated or carbon-steel alternatives

What hardware and installation details should I know?

This CURT ball includes a zinc-plated hex nut and a helical lock washer, and features fine threads for enhanced holding strength. Proper torqueing (250 lb.-ft. recommended for final tightening) and checking the nut/security after initial use are important for safe towing.

• Fine-threaded shank for improved nut engagement and clamp strength
• Supplied zinc-plated hex nut and helical lock washer for secure installation
• Recommended torque specification for installation to ensure safe mounting
