CURT 2 in Trailer Ball Chrome with 2 in Rise Shank — 2 in Diameter, 6,000 lb Capacity

CURT 40034 is a 2-inch diameter chrome trailer ball with a 2-inch rise and a 6,000 lb gross towing capacity, built from hot-forged steel for dependable towing performance.

When you need a reliable connection between your vehicle and trailer, the right trailer ball makes a big difference. The CURT 40034 is engineered to fit standard 2" couplers while delivering a secure, corrosion-resistant towing surface. It combines precise dimensions, fine-threaded shank hardware, and VESC-tested quality so you can hitch up quickly and tow with confidence.

How does the CURT 40034 ensure a secure hitch connection?

This trailer ball uses a fine-threaded 1" shank and comes with a zinc-plated hex nut plus a helical lock washer to keep the ball firmly fastened to the mount. The fine threads provide increased clamping strength and smoother torqueing during installation, reducing the chance of loosening under load.

• 1" shank diameter with 2-1/8" shank length for a tight fit
• Fine threads for stronger hold and accurate torqueing (250 lb.-ft. required)
• Zinc-plated hex nut and helical lock washer included for secure fastening

What towing capacity and coupler compatibility does it offer?

The CURT 40034 is rated for a 6,000 lb gross trailer weight and fits any standard 2" trailer coupler. It’s suitable as an extension of Class 3 or Class 4 hitch setups, but you must not exceed the lowest rated component in your towing system (vehicle, hitch, mount, or trailer).

• 2" ball diameter to match standard 2" couplers
• 6,000 lb gross trailer weight rating for light- to medium-duty towing
• Ideal for utility trailers, boat trailers, campers, ATVs, and more

How does the chrome finish affect longevity and maintenance?

The polished nickel-chrome plating protects the ball from rust, scratches, and road grime, extending service life and preserving appearance. Routine cleaning and periodic inspection of the threads and mounting hardware will maintain reliability and prevent corrosion-related issues.

• Durable chrome plating resists rust and surface wear
• Easy to wipe clean after rainy or salty-road exposure
• Inspect threads and washer for wear at regular intervals

What mounting dimensions and fitment details should I check before buying?

Confirm your ball mount’s hole diameter accepts a 1" shank and that the available shank length accommodates the 2-1/8" length. Also verify the rise needed to level your trailer; this ball provides a built-in 2" rise to help achieve proper trailer attitude during towing.

• Shank: 1" diameter, 2-1/8" length — fits standard mounting holes
• Rise: 2" built-in rise for level towing on many setups
• Torque spec: tighten to 250 lb.-ft. for secure installation

Who this is for: The CURT 40034 is aimed at pickup and SUV owners who tow light- to medium-duty trailers and want a rugged, precisely made 2" trailer ball. It's a good choice for owners of utility trailers, boats, campers, ATVs, and similar loads who need corrosion resistance, tested safety standards, and a dependable threaded connection. Always match the ball’s rating to your entire towing system and follow manufacturer torque and inspection guidelines before each trip.
