CURT Class III Loaded Ball Mount with 2-5/16" Ball — 4" Drop, 7,500 lb GTW

CURT 45042 is a ready-to-tow Class III loaded ball mount with a factory-torqued 2-5/16" trailer ball rated for 7,500 lbs gross trailer weight and 750 lbs tongue weight.

This loaded ball mount arrives complete with a matched CURT 2-5/16" trailer ball and the pin and clip needed to secure it in a 2" x 2" receiver. Because the ball is installed and torqued at the factory, you skip the extra step of mounting and torque-checking a separate ball. The 8-1/4" overall length and 4" drop give you common clearance and leveling options for boats, campers, utility trailers and a wide range of recreational trailers, while a gloss black powder coat helps resist rust and wear from road exposure.

How does this ball mount make hitching easier?

The CURT 45042 is shipped pre-assembled with a factory-torqued trailer ball, so you don’t have to install or torque the ball yourself. It also includes the pin and clip to lock the mount in a standard 2" receiver tube, so the unit is usable straight from the box for most towing tasks.

• Factory-installed 2-5/16" ball — no separate assembly needed
• Includes pin and clip for quick receiver installation
• 2" x 2" shank fits common Class III hitches
• Ready-to-use for many trailers without extra tools

What towing capacities and trailer types is this suited for?

This loaded ball mount carries a 7,500 lb gross trailer weight (GTW) rating and a 750 lb tongue weight (TW) rating, making it appropriate for many midsize towing tasks. Typical applications include boat trailers, utility trailers, small campers, and trailers hauling ATVs or motorcycles, but always observe the lowest-rated component in your towing system.

• 7,500 lb gross trailer weight capacity
• 750 lb tongue weight capacity
• 2-5/16" ball accepts common couplers used on larger trailers
• Good fit for boats, campers, utility and recreational trailers

Will this mount provide proper trailer leveling and fit my vehicle?

The 4" drop on this 8-1/4" length ball mount gives a practical amount of downward offset for many tow vehicle/trailer height combinations. Because the shank is the standard 2" x 2", it installs in the majority of Class III receivers, but you should verify vehicle, hitch and trailer coupler heights before towing.

• 4" drop for common leveling needs
• 8-1/4" overall length for compact clearance
• Standard 2" x 2" shank fits Class III receivers
• Hollow shank reduces weight and accepts anti-rattle kits

How does the finish and construction affect durability?

The mount's gloss black powder coat finish guards against rust, chipping and UV exposure for longer service life on-road and in storage. CURT manufactures its loaded ball mounts to meet typical industry strength and durability expectations, combining a hollow steel shank with a solid ball mount body for a balance of weight and robustness.

• Gloss black powder coat resists rust and UV damage
• Hollow shank lowers weight and accepts anti-rattle hardware
• Factory-torqued ball reduces risk of loose fasteners
• Manufactured to CURT standards for consistent quality

Who is this for? The CURT 45042 loaded ball mount is aimed at owners of Class III hitch-equipped vehicles who want a reliable, out-of-the-box towing solution for medium-duty trailers. It’s ideal for boat owners, small RV and camper users, utility and livestock trailer operators, and recreational trailer owners who prefer a pre-assembled, properly torqued ball and the convenience of a complete, ready-to-use mount. Always confirm your vehicle, hitch and trailer ratings and never exceed the lowest rated component in your towing system.
