CURT 2" Class III Loaded Ball Mount with 1-7/8" Ball, 3,500 lb GTW, Gloss Black

CURT 45055 is a ready-to-use Class III loaded ball mount with a pre-torqued 1-7/8" trailer ball, rated for 3,500 lb gross trailer weight and 350 lb tongue weight.

This loaded ball mount arrives with the trailer ball already installed and factory-torqued, plus the mounting pin, so you can attach it to a 2" receiver and tow immediately. Built on a 2" x 2" shank and finished in gloss black powder coat, the 45055 is engineered for routine towing tasks like small boats, utility trailers and lightweight campers while resisting rust and surface damage.

How will this ball mount fit my vehicle and hitch?

The CURT 45055 uses a standard 2" x 2" shank that slides into most Class III 2" receiver hitches. Its 5/8" pin hole aligns with common hitch pins for a secure connection.

• 2" x 2" shank fits industry-standard Class III receivers
• 5/8" pin hole accepts common hitch pins or clips
• 8-1/4" overall length provides compact clearance behind the bumper

What towing loads and trailer types is it appropriate for?

This ball mount is rated for a gross trailer weight of 3,500 lb and a tongue weight of 350 lb, making it suitable for many small trailers. It’s ideal for lightweight boat trailers, utility trailers, pop-up campers and many bike or ATV transport trailers, as long as you don’t exceed any component’s lower-rated limit.

• 1-7/8" trailer ball for common small-trailer couplers
• 3,500 lb gross trailer weight and 350 lb tongue weight ratings
• Not suitable for trailers exceeding the lowest-rated towing component

What features make installation and maintenance easier?

The loaded design eliminates the need to buy, mount and torque a separate ball — it comes pre-installed and torqued from the factory. A rounded shank surface and included hitch pin simplify insertion and securing in the receiver, while corrosion-resistant finishes reduce upkeep.

• Pre-torqued trailer ball requires no additional ball-mounting steps
• Included pin and clip for quick receiver attachment
• Gloss black powder coat and polished chrome ball lower maintenance needs

What are the mount’s dimensions and finish details?

The 45055 measures 8-1/4" overall with a 4" drop, designed to provide moderate coupling height adjustment. A gloss black powder coat shields the mount from chipping and UV exposure while the trailer ball receives a polished chrome plating for durability and corrosion resistance.

• Overall length: 8-1/4"; drop: 4" for common hitch heights
• Gloss black powder coat protects the shank and bar from weathering
• Polished chrome-plated 1-7/8" ball for clean appearance and rust resistance

Who this is for: The CURT 45055 loaded ball mount is best for owners of light towing rigs who want a reliable, out-of-the-box solution. If you tow small boats, utility trailers, lightweight campers or recreational trailers under the stated capacities and use a 2" receiver, this pre-assembled mount saves time and ensures the ball is torqued correctly. Choose a different CURT model if you need higher weight ratings, a different ball size, or alternative drop/rise measurements.
