CURT 2" Trailer Hitch Ball Mount with 2" Ball, 2" Drop — 7,500 lb One‑Piece Welded Fusion

CURT 45134 Fusion is a one-piece, permanently welded ball mount with a 2" trailer ball and a 7,500 lb gross trailer weight rating for secure, ready-to-tow performance.

This Fusion ball mount pairs a welded 2" trailer ball with a 2" x 2" shank to deliver a compact, heavy-duty towing solution that’s ready the moment you unpack it. Designed and robotically welded by CURT, the 45134 removes the need to attach a separate ball and reduces the risk of loosening or theft. Finished in gloss black powder coat with a polished chrome ball, it balances corrosion resistance with professional appearance for everyday towing tasks.

How does the permanently welded ball improve towing reliability?

Because the trailer ball is permanently welded to the shank, there are no threaded connections that can loosen over time. That increases structural integrity under load and removes a common maintenance step. It also prevents ball removal or theft at rest.

• One-piece construction with robotic welding for consistent, strong welds
• No threaded ball to check or retighten before each trip
• Reduced chance of hardware loosening under vibration or heavy use

Will this ball mount fit my receiver and trailer coupler?

The CURT 45134 is made for standard 2" hitch receivers and trailers with a 2" coupler. Its 2" x 2" shank fits typical 2" receivers, and the welded 2" ball mates with most common trailer couplers for utility trailers, boats, campers and more. Always verify the lowest-rated component in your towing system.

• 2" x 2" shank designed for 2" receiver openings
• Permanently attached 2" ball to match 2" trailer couplers
• Works with a wide range of trailers when capacities align

How durable is the finish and how is it protected from corrosion?

After robotic welding and a thorough cleaning process, the ball mount receives a durable gloss-black powder coat to resist chips and corrosion. The trailer ball itself is plated in polished chrome for added rust resistance and an attractive finish. This combination helps the mount hold up to road exposure and seasonal use.

• Gloss-black powder coat over a cleaned, welded surface
• Polished chrome-plated permanent trailer ball for corrosion resistance
• Manufacturing process prioritizes consistent cuts and clean weld lines
