CURT 2" Receiver Ball Mount with Welded Sway-Control Tab — 7,500 lb Capacity, 3/4" Rise or 2" Drop

CURT 45820 is a heavy-duty 2" receiver ball mount with a welded sway-control tab to attach CURT sway control hardware for safer towing.

Built for tougher towing conditions where sway control is needed but a weight-distribution system isn’t desired, this specialty ball mount combines a conventional trailer ball platform with an integrated tab for a sway control ball. It fits standard 2" x 2" hitch receivers, accepts a 1" trailer ball shank on the platform, and provides a dedicated 5/8" mounting hole on the tab to pair with CURT sway control components. Finished in a gloss black powder coat, the 45820 resists corrosion and surface wear for long service life on work sites, farms, and recreational hauls.

How does this ball mount add sway control without a weight distribution hitch?

The 45820 includes a welded tab behind the trailer ball platform sized to accept CURT sway control hardware, so you attach a sway control ball and shank assembly directly to the mount. This arrangement lets you control lateral trailer movement while retaining a standard ball mount profile and operation.

• Welded sway-control tab with 5/8" mounting hole for CURT sway ball #40093
• Uses separate CURT sway control unit (e.g., #17200) for friction-based damping
• No need to install a weight-distribution shank to gain sway reduction
• Compatible with conventional 1" trailer ball on the main platform

What towing capacities and height options does this mount offer?

This mount is rated for up to 7,500 lbs. gross trailer weight and 750 lbs. tongue weight, suitable for many larger utility, livestock, and travel trailers. The forged platform is available in a 3/4" rise or 2" drop configuration to help you achieve correct trailer pitch and level towing.

• 7,500 lb gross trailer weight capacity
• 750 lb tongue weight capacity
• Height choices: 3/4" rise or 2" drop for level trailer setup
• Accepts standard 1" ball shank on the main platform

Will this fit my vehicle and how does it install?

The 45820 is engineered to slide into any 2" x 2" receiver tube and secures with a standard hitch pin or locking hitch pin (not included). Installation mirrors that of a regular ball mount: insert, align pin holes, and secure—then add the trailer ball and sway hardware as needed.

• Compatible with 2" x 2" receiver openings
• Secures using common hitch pin or lock (sold separately)
• Platform drilled for 1" ball; tab drilled for 5/8" sway ball
• Gloss black powder coat reduces rust and surface damage

What materials and finish protect it from wear outdoors?

Constructed for heavy use, the ball mount is welded and finished with a durable gloss black powder coating that stands up to road debris, moisture, and UV exposure. The coating helps preserve fitment and appearance through repeated seasonal use.

• Welded steel construction for structural strength
• Gloss black powder coat for corrosion and scratch resistance
• Designed for frequent hookup and rough-terrain use
• Pairs with CURT sway components for integrated performance

Who is this for: The CURT 45820 sway tab ball mount is aimed at drivers who tow heavier trailers and want a simple, bolt-on method to add sway control without converting to a weight-distribution hitch. It’s a practical choice for farmers, landscapers, RV owners, and weekend haulers who need a durable, receiver-mounted solution that fits standard 2" hitches and works with CURT sway control parts.
