CURT 2" Fusion Welded Ball Mount with 2" Trailer Ball — 7,500 lb Rated, Gloss Black

The CURT Fusion 45155 is a one-piece welded ball mount with a permanently attached 2" trailer ball, rated for 7,500 lb gross trailer weight and designed for 2" receiver hitches.

If you need a compact, rugged hitch accessory that’s ready to tow straight from the box, the CURT Fusion 45155 offers a fixed-ball design that eliminates loosening and theft risks while adding strength versus removable-ball mounts. Robotically welded for consistent seams and finished in a durable gloss black powder coat, this ball mount pairs a 2" x 2" shank with a 2" diameter chrome-plated ball and includes a hitch pin and clip for fast installation.

How does the permanently welded ball improve towing reliability?

A welded trailer ball eliminates the common failure points associated with removable balls: threaded interfaces, backing nuts and potential loosening. Because the ball is integral to the shank, the load path is simplified and theft or accidental loosening is impossible.

• One-piece welded construction for consistent strength under load
• Robotic welding ensures precise alignment and clean welds
• Permanently attached ball removes backing nut failure and theft risk

What vehicles and trailers is this Fusion mount compatible with?

The Fusion 45155 is built around a 2" x 2" shank, making it compatible with standard 2" receiver hitches found on many trucks, SUVs and vans. It’s suited for trailers that use a 2" coupler and whose weight does not exceed the lowest-rated component in the towing system.

• Fits 2" receiver hitches — not compatible with 1-1/4" receivers
• Use with trailers that have a 2" coupler
• Appropriate for utility trailers, boat trailers, campers and similar loads

What load ratings and dimensions should I check before towing?

The Fusion 45155 carries a gross trailer weight rating of 7,500 lb and a tongue weight rating of 750 lb. Always confirm the vehicle, hitch, and trailer ratings, and ensure you do not exceed the lowest rating in the towing chain.

• Gross trailer weight (GTW): 7,500 lb
• Tongue weight (TW): 750 lb
• Overall length: 8-1/8" with 2" rise; 2" diameter trailer ball

How durable is the finish and how is it maintained?

After welding, each unit undergoes surface preparation to ensure the powder coat adheres evenly. The gloss black powder coat protects against chipping and corrosion, while the trailer ball is chrome-plated for long-term outdoor exposure.

• Gloss black powder coat resists rust and chips
• Polished chrome-plated ball for corrosion resistance and smooth coupler contact
• Wipe clean with mild soap and water; inspect welds and finish periodically

Who is this for: The CURT Fusion 45155 is ideal for vehicle owners who tow regularly and prefer a low-maintenance, theft-resistant solution. Choose this ball mount if you have a 2" receiver, plan to tow trailers with a 2" coupler, and want a compact, durable one-piece mount rated up to 7,500 lb GTW. If you need adjustable drop/rise options or removable-ball flexibility, consider other CURT models instead. Always verify vehicle, hitch, and trailer ratings before use to ensure safe towing.
