CURT 2x2 Ball Mount with Welded Sway Tab — 1" Ball Hole, 7,500 lb GTW

CURT 45820 is a heavy-duty 2"x2" ball mount that combines a standard trailer ball platform with a welded sway-control tab for attaching CURT sway control components.

Designed for more rugged towing conditions, the CURT 45820 specialty ball mount lets you add sway control without installing a weight-distribution hitch. It fits any 2" x 2" receiver and provides a 1" hole for a standard trailer ball shank plus a 5/8" diameter sway control tab to accept the CURT sway control ball. Finished in gloss black powder coat, this mount balances strength and corrosion resistance for dependable trailering on highways, back roads, and farm fields alike.

How does this ball mount add sway control when I don’t want a weight-distribution hitch?

The 45820 includes a welded tab specifically sized for a sway-control ball, enabling a two-point sway control unit to connect directly to the mount. That means you can reduce lateral trailer movement without the added complexity or hardware of a weight-distribution system.

• Welded sway-control tab accepts CURT sway control ball #40093 (5/8" diameter).
• Works with CURT sway control unit #17200 for friction-based damping.
• Maintains conventional towing ball location via the 1" platform hole.

What towing capacity and tongue weight can I expect from the 45820?

This specialty ball mount supports substantial towing loads suitable for many larger trailers. It is rated for a gross trailer weight of 7,500 pounds with a tongue weight capacity of 750 pounds, making it right for boats, utility trailers, and small equipment haulers within those limits.

• Gross Trailer Weight (GTW): 7,500 lbs.
• Tongue Weight (TW): 750 lbs.
• Use within vehicle and trailer manufacturer weight limits for safe operation.

Will this mount fit my hitch and trailer ball setup?

The CURT 45820 is made to fit standard 2" x 2" receiver tubes and accommodates a common 1" diameter ball shank hole. It also provides two position vertical geometry—3/4" rise or 2" drop—so you can achieve a level trailer stance when combined with the proper ball and shank length.

• Receiver compatibility: 2" x 2".
• Trailer ball platform: 1" hole for standard shanks.
• Height options: 3/4" rise or 2" drop for leveling flexibility.

How durable is the 45820 for off-road or corrosive conditions?

CURT finishes this mount in a gloss black powder coat designed to resist scratches, UV exposure, and corrosion better than plain painted surfaces. Robust welds and heavy-gauge steel construction ensure the sway tab and ball platform remain aligned and secure under repeated towing stress.

• Gloss black powder coat for corrosion and UV resistance.
• Heavy-gauge steel with reinforced welded tab for durability.
• Manufactured to handle farm, trail, and highway use.

Who is this for: The CURT 45820 Sway Tab Ball Mount is aimed at drivers who tow medium-to-large trailers and want to add sway control without the bulk of a weight-distributing hitch. It's ideal for owners of boats, landscaping or equipment trailers, and recreational trailers who use a 2" receiver and need a reliable, corrosion-resistant mount with both standard ball installation and a dedicated sway-control attachment point.
