CURT 1in Ball Mount Class III 2x2 Shank — 6in Drop / 4in Rise, 7,500 lb GTW, Gloss Black

The CURT 45070 Class III 1" Ball Mount is a heavy-duty, CNC-formed 2" x 2" hitch insert that delivers up to 7,500 lbs gross trailer weight in the 6" drop position and a durable powder-coat finish for long-lasting towing performance.

If you tow boats, campers, utility trailers or other mid-size loads with a pickup or SUV, the CURT 45070 provides a reliable, industry-standard connection between vehicle and trailer. Engineered as a Class III ball mount, it balances strength and versatility: CNC-formed steel and robotic welding ensure consistent build quality, while the reversible shank offers both drop and rise positions to help you achieve a level tow.

How does this ball mount handle different trailer heights?

Flip the mount to choose the orientation that matches the trailer coupler height. In the drop position it lowers the trailer tongue; flipped it provides a rise to align higher trailers with the vehicle's hitch.

• Drop position: 6" drop for lower-coupler trailers.
• Rise position: 4" rise for taller trailers or haulers.
• Reversible design removes the need for multiple mounts for common height differences.

What towing capacity and compatibility should I expect?

The 45070 is rated to support medium-duty towing within Class III limits, but always defer to the lowest-rated component in your towing system. Compatibility centers on the 2" x 2" receiver and a separate 1" hitch ball (sold separately) that fits the 1" shank hole.

• Maximum GTW (drop): 7,500 lbs with 750 lbs tongue weight.
• Maximum GTW (rise): 6,000 lbs with 600 lbs tongue weight.
• Fits standard 2" hitch receivers and accepts a 1" diameter hitch ball shank.

What materials and finishes protect this hitch from the elements?

Curt builds the 45070 from high-strength steel with precision forming and robotic welds to reduce weak points. A thick gloss black powder-coat finish resists corrosion, road debris, UV and abrasion so it stays serviceable season after season.

• CNC-formed steel body for dimensional accuracy and strength.
• Robotic welding for consistent weld quality across units.
• Gloss black powder-coat finish for corrosion and scratch resistance.

How simple is installation and use?

Installation is straightforward: insert the rounded 2" x 2" shank into a matching receiver and secure with a hitch pin (sold separately). The machined 1" hole accepts standard hitch balls, making hookup fast at the trailhead or marina.

• Rounded shank eases insertion into the receiver sleeve.
• 1" hole accepts common trailer hitch balls (ball sold separately).
• Secure with a standard hitch pin and clip (not included).

Who is this for: The CURT 45070 is aimed at pickup and SUV owners who need a dependable Class III ball mount for utility trailers, boats, campers and similar mid-sized loads. It's a sensible upgrade for drivers who prioritize durable construction, straightforward mounting, and the flexibility to adapt to different trailer tongue heights without buying multiple mounts. Always check your vehicle, hitch, and trailer ratings and never exceed the lowest capacity among them.
