CURT Fusion 2" Welded Ball Mount with 2" Trailer Ball — 2" x 2" Shank, 7,500 lb Capacity

This Fusion ball mount combines a fixed 2" diameter trailer ball and a 2" x 2" shank into a single welded assembly designed for dependable, ready-to-tow performance. Unlike removable loaded ball mounts, the permanently attached ball eliminates the risk of loosening or theft and improves structural integrity. The unit is robotically welded, finished in gloss black powder coat for corrosion resistance, and ships with a hitch pin and clip so you can install it quickly into any compatible 2" receiver.

How strong is the CURT 45155 for everyday towing?

The 45155 is rated for a gross trailer weight (GTW) of 7,500 pounds and a tongue weight (TW) of 750 pounds, making it suitable for many common trailers when matched with properly rated vehicle and hitch components. Always follow the lowest-rated component in your towing setup to stay within safe limits.

• 7,500 lb gross trailer weight capacity
• 750 lb tongue weight capacity
• Robotically welded one-piece construction for consistent strength

Will this ball mount fit my hitch and trailer?

The shank measures 2" x 2", so it fits standard 2" receiver hitches. The permanently attached trailer ball is 2" in diameter and intended for trailers with 2" couplers; it will not fit 1-1/4" receivers or couplers of mismatched size.

• 2" x 2" shank to fit 2" receivers
• 2" diameter welded trailer ball for 2" couplers
• Includes hitch pin and clip for secure mounting

What are the durability and finish details?

After robotic welding and cleaning, the ball mount receives a high-gloss black powder coat that resists chipping and corrosion. The welded trailer ball itself is chrome-plated and polished to provide long-term wear resistance and a smooth mating surface for couplers.

• Gloss black powder coat on the body for corrosion resistance
• Polished chrome-plated trailer ball for durability and smooth coupling
• Precision welding for consistent, clean weld lines

How easy is it to install and use each time?

Installation is straightforward: slide the rounded shank into a compatible 2" receiver and secure it with the included pin and clip. Because the ball is permanently welded, you won’t need to tighten a ball-to-mount fastener before towing and there’s no risk of the ball working loose during use.

• Ready-to-tow out of the package—no separate ball to attach
• Included hitch pin and clip simplify install and removal
• Fixed ball design prevents loosening and theft

Who is this for? The CURT 45155 Fusion ball mount is aimed at drivers who tow standard utility trailers, small campers, boats, or livestock trailers and want a robust, low-maintenance hitch solution. It’s a practical option for owners of vehicles with 2" receiver hitches who prioritize a welded, tamper-resistant ball mount with a polished finish and industry-standard weight ratings. Remember to verify the towing capacities of your vehicle, hitch, and trailer and never exceed the lowest-rated component.
