CURT 2" Class III Ball Mount 45040 — 2" Receiver, 7,500 lb GTW, 2" Drop (Gloss Black)

The CURT 45040 Class III 2" ball mount is a heavy-duty, powder-coated steel tow mount rated for 7,500 lb gross trailer weight and 750 lb tongue weight.

Designed for pickup trucks and SUVs with a 2" receiver, this Class III ball mount combines CNC-formed construction and robotic welding with a corrosion-resistant gloss black powder coat. It gives you a dependable hitch solution for utility trailers, boat trailers, campers and most recreational trailers while fitting standard 2" x 2" receiver tubes.

How much weight can this ball mount safely tow?

This CURT ball mount is stamped and rated for a 7,500 lb gross trailer weight (GTW) and a 750 lb tongue weight (TW). Always verify the lowest-rated component in your towing system — vehicle, hitch, ball mount and trailer — and never exceed that lowest limit.

• Gross trailer weight capacity: 7,500 lb
• Tongue weight capacity: 750 lb
• Follow the lowest-rated towing component rule
• Trailer ball sold separately; choose correct ball rating

Will this mount fit my vehicle and trailer ball?

The 45040 has a 2" x 2" shank to match industry-standard 2" receivers on most trucks and SUVs. It accepts a trailer ball with a 1" diameter shank through the 1" hole in the mount (ball and ball hardware not included).

• Shank size: 2" x 2" for standard receivers
• Ball hole diameter: 1" to fit common trailer balls
• Secure with hitch pin and clip (not included)
• Rounded shank eases insertion and alignment

What are the dimensions and adjustment options?

The mount measures 10-1/4" long overall and offers a 2" drop with a possible 3/4" rise, letting you level many trailers without extra accessories. Its geometry supports common trailer heights for boats, campers and utility trailers.

• Overall length: 10-1/4"
• Drop: 2" for lower trailer tongues
• Rise: up to 3/4" if needed for level towing
• Compact profile reduces interference and improves clearance

How is durability and finish handled for long-term use?

CURT CNC-forms and robotically welds each mount for consistent strength, then mechanically descales before applying a gloss black powder coat. That finish resists rust, scratches, UV and road contaminants for long-lasting service life on the road.

• High-strength steel construction for structural reliability
• Mechanical descaling creates a smooth prep surface
• Gloss black powder coat protects against corrosion and wear
• Precision welding minimizes weak points and variability

Who is this for: The CURT 45040 is aimed at pickup and SUV owners who routinely tow heavier trailers — boats, campers, utility trailers or livestock trailers — and need a rugged, industry-standard 2" ball mount with reliable capacities. If your setup requires a compact, corrosion-resistant Class III mount with a 2" drop and modest rise capability, this unit is an appropriate, easy-to-install choice. Remember to match it to the lowest-rated towing component in your system and to select a compatible trailer ball and hitch pin for secure towing.
