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

CURT 48004 is a heavy-duty receiver-mounted pintle hook engineered to connect 2-1/2" lunette rings to any standard 2" x 2" trailer receiver, rated for up to 20,000 lbs gross trailer weight.

Built for demanding uses like agriculture, construction, and other heavy towing tasks, this pintle hook pairs a simple, rugged coupling design with a solid forged-steel shank and a protective powder-coat finish. Its compact receiver mount makes it compatible with most class 5 hitch systems, while the included safety pin and spring-loaded locking arm keep the connection secure under load. As with all towing components, match the lowest rated element in your system — vehicle, hitch, or trailer — and never exceed published capacities.

How does this pintle hook attach to my vehicle?

The CURT 48004 inserts into any 2" x 2" receiver tube and secures with a standard hitch pin. Its solid shank and forged-steel construction provide a durable connection point for lunette-ring-equipped trailers, and the spring-loaded locking arm helps prevent accidental uncoupling during towing.

• Fits standard 2" x 2" receiver tubes (common on class 5 hitches)
• Secures with included safety pin for reliable retention
• Spring-loaded lock arm reduces play and accidental release
• Forged steel shank ensures long-term structural strength

What size lunette ring does it accept and what is the rating?

This pintle hook is made to couple with lunette rings that have a 2-1/2" inside eye diameter. It carries a gross trailer weight rating of 20,000 lbs, suitable for many heavy trailers, but you should always confirm the lowest-rated component in your towing setup to determine safe limits.

• Compatible with 2-1/2" inside-diameter lunette rings
• Gross trailer weight capacity: 20,000 lbs (match system limits)
• Designed for heavy-duty towing applications
• Not a substitute for checking vehicle and trailer ratings

What materials and finish protect it from wear and weather?

The CURT 48004 is forged from solid steel for maximum strength, then finished with a black powder coat that resists surface corrosion and scuffs common in rugged environments. The finish extends component life and helps maintain reliable function even when used frequently on job sites or farms.

• Forged steel construction for superior tensile strength
• Durable black powder coat protects against rust and scratches
• Engineered to withstand repeated heavy-duty coupling cycles
• Low-maintenance finish suitable for outdoor use

How do I use and maintain the pintle hook safely?

Installation is straightforward: slide into the receiver, align the pinholes, then insert the hitch pin and engage the spring-locking arm. Regular inspection for wear, proper engagement of the latch, and corrosion control will keep the coupling secure and extend service life.

• Insert into 2" receiver and lock with hitch pin and clip
• Verify spring-loaded arm fully engages the lunette ring
• Inspect for cracks, excessive wear, or loose hardware before each tow
• Touch up finish or lubricate pivot points if corrosion appears

Who is this for: The CURT 48004 is intended for owners and operators who tow heavy loads with lunette-ring-equipped trailers — think farm equipment haulers, construction trailers, military-style trailers, or any application needing a simple, high-capacity hitch. It's a practical choice for professionals and serious owners who need rugged, low-maintenance towing hardware that pairs with a standard 2" x 2" receiver.
