CURT Fusion Ball Mounts with 1-7/8″ Balls (2″ Shank, 5,000 lbs., 2″ Rise, 2-Pack) #45157


SKU: 612314003662 Category:


Arm yourself with confidence with a CURT Fusion ball mount. Much like our loaded ball mounts, CURT Fusion mounts come with a trailer ball pre-attached to the mounting platform to provide a ready-to-tow solution right out the package. Unlike a loaded ball mount, however, a Fusion ball mount features a trailer ball that is permanently fixed to the shank structure, making it stronger than a traditional non-welded ball mount. With their fixed tow ball, Fusion ball mounts are also very similar to our Euro Mount ball mounts. Besides increased strength, one advantage of a permanently attached trailer ball is that it can never be loosened or stolen from your vehicle. CURT Fusion ball mounts come with 2″ x 2″ shanks and include a pin and clip with each unit.

This ball mount multi-pack comes with two Fusion mounts, each with a gross trailer weight capacity of 5,000 lbs. and a tongue weight rating of 500 lbs. They measure 8-1/8″ long, have 2″ of rise and come with 1-7/8″ diameter trailer balls. CURT Fusion ball mounts are great for towing most standard size trailers, including utility trailers, livestock trailers, boat trailers and campers (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Each unit is robotically welded to ensure accurate, consistent cuts and clean, strong weld lines. Once welded, these ball mounts undergo a cleaning process that creates a flawless surface for the application of our highly durable gloss black powder coat finish for long-lasting resistance to corrosion and chipping.
