CURT Forged 2-1/2" Ball Mount 2-1/2" x 2-1/2" Shank — 4" Drop, 20,000 lb Capacity

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

Built for contractors, farmers, and fleet operators who need dependable heavy-haul hardware, this forged CURT ball mount replaces multi-piece or welded designs with a single solid-steel construction. Its 2-1/2" x 2-1/2" shank fits large receivers and the carbide powder-coat finish helps resist corrosion and wear from daily use. The engineered geometry — 4" drop, 2-1/2" rise, and 8-1/2" overall length — balances clearances and loading for a wide variety of trailers.

How strong is this ball mount and what loads can it handle?

This CURT forged ball mount is designed to carry substantial commercial loads without compromise. Its single-piece forged steel construction delivers superior strength compared with welded or bolted designs, and it’s tested for the rated capacities shown.

• Gross Trailer Weight (GTW): up to 20,000 lb
• Tongue Weight (TW): up to 2,700 lb
• 1-1/4" ball hole accepts standard commercial hitch balls
• Engineered to resist stress concentrations common to weld joints

Will this fit my hitch and trailer setup?

The CURT 45458 fits any receiver with a 2-1/2" x 2-1/2" opening and uses a 1-1/4" ball hole for common commercial hitch balls. Its fixed rise and drop let you match trailer and vehicle heights without stacking adapters.

• Shank size: 2-1/2" x 2-1/2" for class 5 receivers
• Drop: 4" — ideal for lower trailer tongues
• Rise: 2-1/2" — useful for taller tongue profiles
• Length: 8-1/2" overall for ground and bumper clearance

How does the finish and construction affect durability?

The one-piece forged design eliminates welds that can crack under heavy, repeated loading. A black carbide powder-coat provides a hard, wear-resistant outer layer that shields the steel from rust, abrasion, and UV exposure encountered on job sites and farms.

• Zero-weld forging reduces failure points under cyclic stress
• Carbide powder coat resists chips, corrosion, and fading
• Solid steel core for extended service life in harsh conditions
• Built to pair with CURT class 5 commercial hitches and heavy trucks

What practical advantages does this offer in day-to-day use?

Because it’s purpose-built for heavy-duty towing, the 45458 simplifies rigging and improves confidence on the road. The fixed dimensions make hookup predictable and the high capacities reduce the need for multiple adapters or makeshift solutions.

• Saves time with a durable, ready-to-use mount for commercial trailers
• Reduces adapter stacking that can weaken towing setups
• Compatible with full-size pickups, flatbeds, and commercial trucks
• Low maintenance—clean and inspect; no routine painting needed

Who is this for? If you operate full-size pickups, commercial trucks, or fleet vehicles that routinely pull heavy loads—dump trailers, car haulers, toy haulers, livestock trailers, or utility trailers—the CURT 45458 answers the need for a rugged, reliable ball mount. It’s targeted at professionals and serious owners who demand a high-capacity, single-piece forged solution that fits 2-1/2" receivers and cuts downtime with fewer component failures. Always ensure no towing component in your system exceeds its rated capacity and consult vehicle and trailer ratings before use.
