Identify CURT 48004, 48005 & 48010 Receiver Pintle Hooks
Replacing a pintle hook removed from a truck's receiver? Three CURT forged-steel models look similar from the side, but differ in shank size and rated towing capacity. Model 48005 is the 10,000 lb version for a 2-inch receiver; 48004 uses the same nominal receiver size but is rated to 20,000 lb; 48010 has a larger 2½-inch shank and is also rated to 20,000 lb.
Identify CURT 48004, 48005 and 48010
| CURT MPN | Receiver shank | Lunette eye ID | Maximum GTW | Overall length |
|---|---|---|---|---|
| 48005 | 2 in | 2½ in | 10,000 lb | 14½ in |
| 48004 | 2 in | 2½ in | 20,000 lb | 14½ in |
| 48010 | 2½ in | 2½ in | 20,000 lb | 14¾ in |
The three parts are pintle-only hitches, not combination ball-and-pintle mounts. They have no trailer ball. All are designed for the manufacturer's specified 2½-inch inside-diameter lunette eye, use a spring-loaded latch, and have a protective black powder-coated finish.
Do not assume all lunette rings fit. CURT specifies a 2½-inch inside-diameter lunette eye for these three hooks. A 3-inch eye that fits a different CURT pintle system is not automatically approved here. All weights shown are gross trailer weight ratings, not allowable tongue weights; the complete tow setup is limited by its lowest-rated component.
Replacement identification checklist
- Find the full part number or rating. 48004 and 48005 both use 2-inch shanks and measure 14½ inches overall, but their 20,000 lb and 10,000 lb capacities differ. Identify by an authoritative MPN or marking, not the shared dimensions.
- Measure the square shank. A 2-inch shank points to the 48004/48005 group, while 48010 is the 2½-inch receiver model. This is the shank dimension, not the lunette-eye diameter.
- Check the lunette ring opening. These models require a 2½-inch inside-diameter eye. Do not substitute a 3-inch ring simply because both are used in pintle towing systems.
- Inspect the latch and safety pin. Look for spring action, damage, corrosion, bent retention components and incomplete closure. The manufacturer supplies a safety pin for the pintle latch, distinct from the receiver shank pin.
- Measure clearance. The two 2-inch-shank units are 14½ inches long. The heavier 2½-inch-shank 48010 is 14¾ inches long. Check clearance around the bumper and trailer articulation.
- Confirm the whole trailer connection. Use the actual receiver and tow vehicle capacities and check the trailer eye rating. A replacement must comply with every component's published limitations.

If the original towing hardware uses a different ring or safety-chain arrangement, compare our trailer safety chain identification and CURT channel lunette-ring identification. The latter covers standard channel-style 3-inch lunette rings and is not a list of automatically compatible rings for these receiver hooks.
