CURT Receiver-Mount Pintle Hook for 2-1/2" Lunette Rings — 2" Receiver, 20,000 lb Capacity, Forged Steel

The CURT 48004 is a receiver-mounted pintle hook that fits 2" x 2" hitches and securely couples to 2-1/2" lunette rings for heavy-duty towing up to 20,000 lbs.

Built for rugged towing where strength and simplicity matter, this CURT pintle hook converts a standard 2" receiver into a heavy-capacity connection point for trailers with lunette rings. Its solid forged-steel construction and spring-loaded locking arm deliver a dependable mechanical coupling, while a black powder-coat finish helps resist rust and surface wear from frequent use in agriculture, construction, or industrial settings.

How does the CURT 48004 attach to my vehicle?

The pintle hook inserts into any standard 2" x 2" receiver tube and secures with the included safety pin. Installation is straightforward: slide the shank into the receiver, align the pinholes, and insert the safety pin. No specialized tools are required for mounting or routine removal.

• Compatible with 2" x 2" receiver tubes (standard Class III/IV openings)
• Solid shank designed for easy slide-in installation
• Includes safety pin for positive retention

What trailer fittings and weight can this pintle hook handle?

This model mates to lunette rings that have a 2-1/2" inside eye diameter and is rated with a gross trailer weight capacity of 20,000 lbs. Always observe the lowest published capacity among the vehicle, hitch, and trailer components; the system’s overall rating is limited by the weakest link. The design is optimized for heavy-duty trailers commonly used in agricultural, construction, and military applications.

• Fits 2-1/2" inside diameter lunette rings
• Gross trailer weight rating: 20,000 lbs (observe system limits)
• Intended for heavy towing and frequent coupling cycles

How does the CURT 48004 stay secure and resist wear?

A spring-loaded locking arm keeps the lunette ring firmly engaged and helps prevent accidental uncoupling during travel. The pintle hook is forged from solid steel to withstand shock and shear forces, and the black powder-coat finish provides a durable barrier against corrosion and surface abrasion. Routine inspection of the latch, pin, and mounting hardware ensures ongoing safe performance.

• Spring-loaded locking arm for reliable retention
• Forged steel construction for impact resistance and durability
• Black powder coat finish reduces rust and scratches

What maintenance and safety checks should I perform?

Inspect the pintle hook, safety pin, and receiver connection before each trip for wear, deformation, or excessive corrosion. Lubricate moving parts if needed and replace any components that show cracking, bending, or excessive wear. Always use the supplied safety pin and verify the lunette ring is properly seated and the locking arm is fully engaged.

• Visual inspection for wear, cracks, or rust before towing
• Lubricate pivot points sparingly to maintain movement
• Replace safety pin or hook if damaged or worn

Who is this for: The CURT 48004 is designed for professionals and serious users who need a straightforward, high-capacity towing connection: contractors, farm operators, heavy-equipment haulers, and organizations that operate trailers with lunette rings. If you require a robust, low-maintenance pintle solution that fits a 2" receiver and handles heavy loads, this pintle hook is a practical option. Always pair it with compatible vehicle and trailer hardware and follow safe towing practices.
