CURT Receiver Pintle Hooks: 48004, 48005 & 48010 Size Guide
CURT's receiver-mounted pintle hooks tow trailers equipped with a compatible lunette eye instead of a conventional ball coupler. Models 48004, 48005 and 48010 are forged-steel, pintle-only units with spring-loaded latches and black powder-coated finishes. Their main selection differences are the square receiver shank size and the rated gross trailer weight.
Choose by receiver opening and towing rating
48005 — 2-inch receiver, 10,000 lbFits a 2 × 2-inch receiver and an approved 2½-inch inside-diameter lunette eye. CURT specifies a 14½-inch overall length and includes a pintle-latch safety pin.
48004 — 2-inch receiver, 20,000 lbUses the same nominal 2-inch receiver opening and 14½-inch length but carries a higher 20,000 lb gross trailer rating. Do not infer the higher capacity from appearance alone.
48010 — 2½-inch receiver, 20,000 lbDesigned for a 2½ × 2½-inch receiver with its own solid shank rather than a smaller shank in an adapter. Overall length is 14¾ inches.
CURT receiver pintle hook size chart
| 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 |
All three are solid forged-steel pintle hooks with a spring-loaded locking arm, a gloss-black powder coat and a safety pin for the pintle latch. The shank retention pin for securing the hitch in the vehicle receiver is a separate fitment check; do not assume it is included.
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.
Before choosing and installing a pintle hitch
- Measure the receiver opening. The 48004 and 48005 use a 2-inch square shank. The 48010 requires a compatible 2½-inch square receiver opening.
- Identify the lunette eye. The manufacturer specifies a 2½-inch inside eye for all three models. Check the ring's inside diameter, its own rating and the trailer's mounting arrangement.
- Choose the required gross trailer rating. CURT rates 48005 to 10,000 lb, while 48004 and 48010 are rated to 20,000 lb. A higher-rated pintle hook does not increase the vehicle or hitch receiver rating.
- Account for shank length and clearance. The 2-inch models measure 14½ inches overall and 48010 measures 14¾ inches. Confirm bumper, tailgate and trailer articulation clearance on your actual tow vehicle.
- Check both retention systems. Secure the shank in the receiver using a correctly sized hitch pin or lock, then engage the pintle's spring-loaded latch and install its safety pin before towing.
- Inspect the complete setup. Check the receiver, lunette eye, hitch structure, wear surfaces and rated safety chains according to the vehicle, trailer and component manufacturers' instructions.
