CURT Fusion welded ball mount with 2" ball, 2" drop — 7,500 lb GTW, chrome ball

CURT 45134 Fusion is a one-piece, welded ball mount with a permanently attached 2" trailer ball rated for 7,500 lb gross trailer weight and 750 lb tongue weight.

This ready-to-tow Fusion ball mount arrives with the trailer ball already fixed to the shank, eliminating loose components and providing added structural reliability compared with removable-ball designs. Built for use with 2" hitch receivers and 2" couplers, the CURT 45134 combines a polished chrome ball, gloss-black powder coat protection and factory welding for consistent strength and long-lasting corrosion resistance.

How does this welded ball mount improve towing reliability?

Because the ball is permanently welded to the mount, there are no threaded connections that can loosen or be stolen. The one-piece construction and robotic welding deliver consistent weld quality and stronger load transfer from trailer to vehicle.

• Permanently attached 2" trailer ball reduces movement and wear
• Robotically welded for accurate, repeatable weld lines
• Chrome-plated ball and powder coat resist corrosion and chipping
• Eliminates need to tighten or replace threaded balls

Will this ball mount fit my hitch and trailer?

The 45134 Fusion uses a 2" x 2" shank designed for standard 2" hitch receivers and a 2" diameter trailer ball for common 2" couplers. Its 2" drop helps achieve a level trailer when paired with many light- and medium-duty tow setups.

• 2" x 2" shank for standard 2" receiver systems
• 2" diameter ball suits 2" trailer couplers
• 2" drop provides level towing with many trailers
• Check lowest-rated component (vehicle/hitch/trailer) before towing

What are the weight capacities and safety features?

This Fusion mount is rated 7,500 lb gross trailer weight (GTW) and 750 lb tongue weight (TW). It ships with a hitch pin and retaining clip so you can secure the mount in your receiver immediately, and the welded ball removes a common failure point found in removable-ball designs.

• 7,500 lb GTW and 750 lb TW ratings listed on the product
• Includes pin and clip for quick installation and security
• One-piece design reduces component failures and theft risk
• Follow vehicle and hitch ratings — never exceed the lowest rating

How durable is the finish and construction for outdoor use?

After precise robotic welding and cleaning, the mount receives a gloss-black powder coat that helps resist abrasion, rust and chipping. The trailer ball is polished and chrome-plated to reduce corrosion where the coupler contacts the ball.

• Gloss-black powder coat for corrosion and chip resistance
• Polished chrome-plated ball for smooth coupler contact
• Robotic welds ensure consistent fabrication and strength
• Designed for repeated outdoor use with routine inspection

Who is this for: The CURT 45134 Fusion ball mount is intended for drivers who tow utility trailers, small campers, boats or livestock trailers with a 2" receiver and 2" coupler, and who value a robust, theft-resistant, ready-to-install solution. It’s a solid choice for owners seeking a low-maintenance, factory-welded towing attachment that simplifies hookup and reduces loose hardware.
