CURT Forged 2-1/2" Ball Mount 2-1/2"x2-1/2" Shank, 20,000 lb GTW, Carbide Powder Coat

CURT 45458 is a one-piece forged 2-1/2" ball mount built for commercial towing, rated to 20,000 lb gross trailer weight and 2,700 lb tongue weight.

When your rig must move heavy loads day after day, weak links are not an option. The CURT 45458 forged ball mount uses a single-piece, zero-weld design and forged steel construction to deliver the strength and durability required for heavy-duty trailers, flatbeds, equipment haulers and more. Its carbide powder coat finish adds corrosion and abrasion resistance for long service life in harsh work environments.

How does the forged one-piece design improve towing performance?

A single-piece forged body eliminates welded joints that can be stress points, so the mount resists fatigue and deformation under repeated heavy loads. That structural integrity provides consistent alignment and dependable connection between vehicle and trailer.

• Zero-weld construction for greater fatigue resistance
• Forged steel provides higher tensile strength than plate-weld designs
• Maintains hitch alignment under continuous heavy use

What towing capacities and fitment should I expect?

The 45458 is engineered for heavy commercial duty: a 20,000 lb gross trailer weight (GTW) and 2,700 lb tongue weight (TW). It fits any 2-1/2" x 2-1/2" receiver tube, making it compatible with class 5 receivers and many commercial hitch setups.

• 20,000 lb GTW and 2,700 lb TW rating
• 2-1/2" x 2-1/2" shank fits class 5 receivers
• Commonly paired with full-size pickups, flatbeds and commercial trucks

What are the physical dimensions and mounting details?

The mount provides multiple height options with a 4" drop and 2-1/2" rise to help level trailers across different setups. It uses a standard 1-1/4" ball hole and measures 8-1/2" overall length for proper clearances on most receivers.

• 4" drop / 2-1/2" rise to accommodate trailer heights
• 8-1/2" overall length for clearance and fit
• 1-1/4" ball hole to accept common shank balls

How does the finish protect the mount in daily use?

The black carbide powder coat adds a hard, abrasion-resistant layer that helps prevent rust, scratches and UV degradation in demanding field conditions. That finish reduces maintenance and helps the mount retain both looks and structural longevity even under salt, mud and road debris exposure.

• Carbide powder coat resists corrosion and abrasion
• UV-resistant pigment reduces finish fading
• Reduces paint chipping around high-contact areas

Who is this for: The CURT 45458 is aimed at professionals and owners who tow heavy trailers regularly—construction contractors, landscapers, agricultural operators, flatbed drivers and owners of full-size pickups or commercial trucks. If your towing needs demand high strength, consistent alignment and long-term durability from a 2-1/2" shank ball mount, this forged CURT mount is designed to meet those requirements. Always verify the lowest rated component in your towing system (vehicle, hitch, ball, coupler) before hauling.
