CURT 2-inch Class III Loaded Ball Mount with 1-7/8-inch Ball — 3,500 lb, Pre-torqued, Gloss Black

The CURT 45055 is a fully assembled Class III 2" loaded ball mount with a pre-torqued 1-7/8" trailer ball, rated for 3,500 lb gross trailer weight and ready to hitch straight from the box.

This loaded ball mount bundles a fitted trailer ball, pin and clip on a 2" x 2" shank to simplify hooking up trailers, boats and light utility loads. The 45055 eliminates the need to install or torque a separate ball, and its gloss black powder-coat and chrome-plated ball offer corrosion resistance for longer service life. With an 8-1/4" overall length and a 4" drop, it fits most standard 2" receivers and suits a wide range of small towing jobs.

What towing capacity and ball size does this mount support?

The CURT 45055 is rated for a gross trailer weight of 3,500 pounds and a tongue weight of 350 pounds when used with the included 1-7/8" ball. These ratings reflect the assembled unit; removing the factory ball can change capacity and requires retorquing and verification.

• Gross trailer weight: 3,500 lb
• Tongue weight: 350 lb
• Pre-installed trailer ball: 1-7/8" diameter
• Designed as a complete, factory-torqued assembly

How does the mount fit my vehicle and receiver?

Designed with a 2" x 2" shank, the 45055 fits any industry-standard 2" receiver found on many SUVs, trucks and crossovers. The 8-1/4" overall length and 4" drop position the ball at a practical height for small trailers without extra adapters.

• Shank size: 2" x 2" to match standard receivers
• Overall length: 8-1/4" for balanced clearance
• Drop: 4" to lower trailer coupler to receiver height
• Pin hole: 5/8" diameter, includes pin and clip

What materials and finishes protect this ball mount?

The 45055 combines a gloss black powder-coat on the shank and bar with a polished chrome-plated trailer ball to resist rust and wear. Those finishes reduce corrosion risk from road grime and moisture, helping the mount stay serviceable without frequent touch-ups.

• Shank and bar: durable gloss black powder-coat
• Trailer ball: polished chrome plating for corrosion resistance
• Factory-assembled to maintain proper torque and alignment
• Built to CURT quality standards for long-term use

How easy is installation and everyday use?

Because the trailer ball is pre-installed and torqued at the factory, installation is simply inserting the shank into a 2" receiver and securing it with the included pin and clip. This ready-to-tow setup saves time and reduces installation steps compared with buying separate components.

• No need to mount or torque a separate trailer ball
• Includes 5/8" pin and clip for quick fastening
• Rounded shank design eases insertion into the receiver
• Works immediately out of the package for convenience

Who is this for? The CURT 45055 loaded ball mount is ideal for drivers who tow small boats, lightweight utility trailers, pop-up campers and similar loads where a 1-7/8" ball and 3,500 lb capacity are appropriate. It suits owners who prefer a plug-and-play towing accessory—those who value a factory-assembled hitch component that reduces setup time and ensures the ball is correctly torqued. Always confirm your vehicle, hitch receiver and trailer capacities before towing and never exceed the lowest rated component in your towing system.
