CURT 2" Class III Ball Mount 45040 — 2" Drop / 3/4" Rise, 7,500 lb Capacity, Black

CURT 45040 is a Class III 2" ball mount engineered to tow up to 7,500 pounds gross trailer weight with durable steel construction and a corrosion-resistant black powder coat.

If you tow trailers, boats, campers or utility loads with a pickup or SUV that uses a 2" receiver, this CURT class 3 ball mount brings a reliable, ready-to-install option. It combines a standard 2" x 2" shank with precise CNC forming and robotic welding so each unit meets consistent strength and fit standards. The mount’s geometry provides a 2" drop and a 3/4" rise option to help you achieve level towing, and the finish fights rust and road wear for long service life.

How much weight can this ball mount handle?

The CURT 45040 is rated for a maximum gross trailer weight of 7,500 pounds and a tongue weight of 750 pounds. Always adhere to the lowest-rated component in your towing system—vehicle, hitch, ball mount or trailer—to determine safe limits.

• Gross Trailer Weight (GTW): 7,500 lbs maximum
• Tongue Weight (TW): 750 lbs maximum
• Limit your towing to the weakest rated part of your setup

Will it fit my vehicle’s hitch receiver?

This ball mount features a 2" x 2" shank, the common industry standard for Class III receivers on trucks and many SUVs. The rounded shank makes insertion straightforward and the 1" hitch-ball hole accepts most 1" shank trailer balls (ball sold separately).

• Shank size: 2" x 2" to fit standard 2" receivers
• Ball hole diameter: 1" to accept standard 1" shank balls
• Install with a hitch pin or locking pin (not included)

How does the drop and rise affect towing setup?

The mount provides a 2" drop and can also be used with a 3/4" rise to help match trailer height to your vehicle for level towing. Proper tongue height keeps load distribution stable and reduces sway or uneven wear on tires and suspension.

• Length: 10-1/4" from shank to ball hole for standard clearance
• Drop: 2" to lower trailer coupler height relative to receiver
• Rise: 3/4" for slight elevation when needed

What makes this CURT ball mount durable and easy to use?

CURT uses CNC forming and robotic welding to provide consistent strength across each unit, and mechanical descaling produces a smooth base for a long-lasting powder coat. The gloss black powder finish resists corrosion, scratches and UV exposure so the mount stays serviceable through road conditions and weather cycles.

• Construction: high-strength steel with precision forming and welding
• Finish: gloss black powder coat to resist rust and road damage
• Preparation: mechanically descaled for better coating adhesion

Who is this for: The CURT 45040 Class III ball mount is aimed at pickup and SUV owners who tow medium to heavy trailers—boats, campers, utility trailers and most recreational trailers—using a 2" receiver. It’s suitable for drivers who value consistent manufacturing, straightforward installation and corrosion protection, and who will match the mount’s rated capacities to their vehicle and trailer limits.
