Identify CURT Adjustable Pintle Mounts by Shank & Plate Size
An adjustable pintle mount can be hard to identify once its label is worn off. CURT uses similar black steel mounting plates across several different load ratings, receiver sizes and shank lengths. Measure the solid receiver shank, mounting-plate height and adjustment holes before selecting the replacement. A matching shape alone does not confirm its safe towing rating.
Identify CURT adjustable pintle mounts by part number
| CURT MPN | Receiver | Maximum GTW | Shank length | Plate height | Positions |
|---|---|---|---|---|---|
| 48323 | 2 in | 10,000 lb | 8½ in | 7 in | 3 |
| 48324 | 2 in | 10,000 lb | 10½ in | 7 in | 3 |
| 48328 | 2 in | 15,000 lb | 8½ in | 7 in | 3 |
| 48325 | 2 in | 15,000 lb | 10½ in | 7 in | 3 |
| 48343 | 2 in | 17,000 lb | 6 in | 7¼ in | 3 |
| 48341 | 2 in | 10,000 lb | 12½ in | 13 in | 6 |
| 48329 | 2½ in | 18,000 lb | 12½ in | 7 in | 3 |
| 48348 | 2½ in | 20,000 lb | 10¾ in | 7¼ in | 3 |
The common 7-inch-tall three-position plates are not all rated alike. CURT 48323 has an 8½-inch shank and is rated 10,000 lb GTW; 48328 has the same nominal shank length and plate height but is rated 15,000 lb. With a 10½-inch shank, 48324 carries 10,000 lb while 48325 carries 15,000 lb. Use an intact label or authoritative identification before assuming the rating.
The tall 48341 has a 13-inch plate with six adjustment positions and a 12½-inch shank. The 48343 has a shorter 6-inch shank and distinctive bent 7¼-inch plate. The heavy-duty 48329 and 48348 belong to the larger 2½-inch receiver family, not the 2-inch family.
Drop orientation only. CURT specifies these models for use in the drop position, not inverted for rise. Their GTW ratings are for the mounting plate, not a guarantee of complete trailer-system capacity or a tongue-weight rating. The actual allowable load is limited by the lowest-rated tow vehicle, receiver, pintle head, mounting hardware, trailer or other connected component.
Replacement identification checks
- Find the exact manufacturer's model number. A used mount with no readable rating should not be assigned a capacity by appearance, finish or hole count.
- Measure the square shank. Distinguish a 2-inch receiver mount from a 2½-inch receiver mount before considering any other measurement.
- Record the shank length. The identified models span 6, 8½, 10½, 10¾ and 12½ inches. Shank length does not describe the height of the pintle hook.
- Count adjustment positions and measure plate height. The 48341 has a 13-inch plate with six settings, unlike the three-position plates. Other models can still share the same plate height but have different capacities.
- Check the attachment bolt pattern. CURT's compatible plate hooks use 1¾-inch vertical by 3 5⁄16-inch horizontal spacing. Check plate damage and use the correct grade, size and installation procedure.
- Check the orientation. These products are for drop-position use only. Inverting the mount is not an approved way to obtain greater height.
- Separate the mount from the attached hook. The mounting plate, bolt-on pintle hook, hitch pin and trailer lunette eye perform different jobs. Confirm each part and rating independently.
